The first post of a "TERMANAL" since 1980s
what in the word are you doing?
its a dump terminal, (means no computer real inside)
is there a computer involved? here? do tell what.
if i google IT, i get 1981.
really? an RS232c ASCII Terminal (yes used many and repaired many in the dark ages of puters)

why in the world fool with this old thing,
it needs to be connected to a computer made from the 1950s to 1980s.
surely you have no such Computer.
worse yet why fix it.?
tell why/?
all these are museum pieces now, all are.
there are web sites with relic schematics,
HP has none, after all , the people that used it are retired now..
like me...

here is a hint of the screen CRT works
make a RS232 loop black plug
so you can type and see your echo.
works all dumbb(sic) terminals
to make it work with real computers takes setting the BAUD rate
stop bits and 7/8 bit mode. and more if it needs modem lines set right.

SOURCE: Where is port to connect USB cable?

I'm sorry you're having trouble with this. I have put together a picture that shows where the mini-USB plug is supposed to be attached to the camera. I hope it helps. This picture actually shows plugging the AV cable into the receptical, but right behind it is the mini-USB port. This is where you connect the USB cable. It looks like you have to lift the flap on the corner to reveal the plugs.

SOURCE: Howto add a network printer on Wyse winterm S30 terminal?

The S30 terminal has the CE 5.0 operating system loaded as default. So you are limited by the operating system and not the hardware when it comes to network printing.

Here is a extract of the release notes for Windows CE 5.0:

"In Windows CE, TCP/IP supports network printing through the Server Message Block (SMB) protocol. It does not provide the Windows Line Printer Remote (LPR) Spooler. However, independent software vendors (ISVs) and original equipment manufacturers (OEMs) can add this support."

In short, you need a 3rd party software program or a (SMB) printer server setup to setup network printing on the S30 terminal..

Wyse also have add-on software to help, if you have CE 5.0 loaded then try the "Thinprint" add-on supplied as a free download by them.
Download Link:
http://www.wyse.com/supportdownload/3series/Addon_ThinPrint_B0010.exe

I haven't tried this, so let me know if it works.

SOURCE: what terminal on the capacitor gets the blue wire from the run terminal on the compressor? Does it go in the terminal with the white wire or the blue wire?

Follow the start wire from the compressor to the capacitor, the run wire will go to the opposite side.
For instance if the white wire is the start wire on your compressor then the run wire will go to blue wire and vice versa.

My rear view mirror camera quit working I checked the fuse it's good the backup lights work.Help


Circuit/System Description
When the transmission is placed into REVERSE, a 12 volt signal is sent to the rearview camera image display module indicating that camera operation is requested. The rearview camera image display module then supplies ignition voltage and ground to the rear vision camera. The rear vision camera sends video information through the rearview camera image display module to the inside rearview mirror through a video signal + and a video signal - circuit. A grounded shielding also wraps the video signal circuits to reduce electronic interference which may degrade the video signal and cause a distorted or otherwise degraded image.

3 way switch wiring diagram


There are several possibilities depending on where the power source enters the circuit. I am currently teaching lessons on Basic electrical circuits. I will add my "Rules of Thumb for wiring switches" I use in my class. You MUST follow the instructions exactly.
Wiring three-way switches.

Rule 1: The incoming hot conductor goes to the nearest common terminal.

Rule 2: The conductor attached to the other common terminal goes to the device. This conductor must be black.

Rule 3: The neutral conductor goes to the device. This conductor must be
white or gray.

Rule 4: Traveler conductors are connected to the remaining terminals on the 3-way switches.

Rule 5: The grounding conductor must be continuous throughout the
circuit.

Wiring diagram for a pickup dump box


If I understand your post correctly, the small terminal is for switch voltage. If you run a jumper wire from B+ to the small terminal, it should activate the solenoid, just for testing. This is just my opinion. If the wire tries to get hot in your hand, disconnect. Of course the proper fix would be to install some kind of switch with circuit protection.
Did this motor come with any instructions? You realize, I can't see anything from here. Use your best judgment.

I need a wiring diagram for an intermatic timer model et70215c


Add a comment and say what voltage you are working with and what you are controlling with timer. Example wiring:
http://waterheatertimer.org/images/Intermatic-et70215cr-wiring-900.jpg

ET70215C timer is a 2-channel timer that can be wired MANY different ways, to control multiple voltages in different ways.
Each channel can be programmed separately to control 2 different loads with different schedules for each load.

Clock terminals are 1 and 2, and default clock voltage is 120Volts, but can be set for 208, 240 or 277Volts.

The switching terminals 3 4 5 6 7 8 are 'dry.' Max load rating is 20 amps per terminal
Dry terminals receive no power when voltage is applied to clock terminals 1 and 2.
This lets you to have 120Volt clock, but control 240Volt circuit with one of the channels, and 24volt with other channel.
Or you can jumper from the clock terminals and put power to terminals 3 and 6 as shown in illustration above.
The timer ALSO has NO and NC terminals that reverse the circuit each time the program turns the switch on-and-off. So when timer program is OFF then power travels from terminal 3 to terminal 5. When program is ON, power travels from terminal 3 to terminal 4.

How do I connect wiring and do programming for P1353 timer for my 2 speed pool pump? Thanks,


P1353 is a very complicated for beginner.
Open following link for manual: P1353 starts on Page 25
http://waterheatertimer.org/pdf/Intermatic-P1353-manual.pdf

Following steps are general introduction.
You can add a comment about specific steps.

1) Select timer voltage: see page 26 manual
http://waterheatertimer.org/images/P1353-voltage-selection-100.jpg
Timer can control 120V or 240V circuits.
P13553 default voltage for clock motor is 240V.
If circuit breaker that supplies power to timer is 240V, then no change is needed.
If circuit breaker that supplies power to timer is 120V, then change jumper on back of timer to 120.
Timer mechanism snaps out of box using thumb spring located top inside box.

2) Wiring
Open link to see general wiring for P1353:
http://waterheatertimer.org/images/P1353-timer-350.jpg
-Bare ground wires connect to green screw

-Line wires are power wires from circuit breaker.
For example Line wires are 240Volt, and there is 1 black wire and 1 white
Black connects to terminal 1
White connects to terminal 2
Add a jumper wire (short piece of same-gauge wire) from terminal 1 to terminal 3
Add a second jumper wire from terminal 3 to terminal 5
This will put power to clock motor and put power to switches

-Load wires go to 2-speed pump: see wiring diagram page 28
There are 3 Load wires for 2-speed pump: Usually these wires are: Black for speed-1, Red for speed-2, and White
Black speed-1 connects to terminal 6
Red speed-2 connects to terminal 4
White motor wire connects to terminal 2 to complete circuit to motor.

3) Programming.
-Manual shows specific programming starting on page 27.
Timer has 3 circuits. Each circuit is independent of other circuit, making this a 3-channel timer.

-Select different MODES when programming timer
Select MODE 2: circuit 1 and circuit 2 will never be ON at same time, which is intended for 2-speed pump operation.

-Programming steps start on page 30 where you select MODE 2
Actual programming steps are straightforward

-Add a comment if you have difficulties and I will answer.

New intermatic T101 timer problem - timer is not


Manual override lever is good overall test of T101 120Volt timer.
T101 timer has 3 terminals: A 1 2

See wiring diagram on following link:
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T101

Electricians test, they don't guess.
So test your wire:
Separate all wires for testing.
Use ordinary 2 prong tester.
Tape wood sticks to tester leads to keep hands away from power.
Stand on dry boards. Do not hold or touch anything metal.
Turn power ON.
Test each wire to bare ground wire.
Tester lights up on Hot wire. 120V circuit has only 1 Hot wire. If you have 2 Hot wires, you might have 240Volt circuit and need T104 timer. If circuit has 1 Hot wire, then that Hot wire must connect to terminal 1.
If you have NO Hot wire, then check circuit breaker.
Hot wire is identified.
Now test Hot wire to all other wires, except bare ground wire.
Tester lights up on Neutral wire. Neutral wire must connect to terminal A.
If you have NO Neutral wire, then additional wiring is needed, or circuit needs further testing to see what type of wiring you are working with.
Bare ground wires connect to green ground screw.

Notice there are small white wires also connected to terminals A and 1. These small white wires power the 120V clock motor. With Hot on terminal 1 and Neutral on terminal A, the clock motor will run, and yellow dial will rotate.

If timer dial does not rotate after connecting Hot ans Neutral, then test voltage across Hot and Neutral to make sure it reads 120V.

Your circuit should have 2 wires remaining.
These wires go to 120Volt load (fan, light, motor)
Connect these two wires to terminals A and 2.
Try manual override.
If Load turns ON-OFF, then timer is wired correctly.
If Load does NOT turn ON-OFF, then reverse Load wires on terminals A and 2.

Add a comment any time.

WH40 water heater timer: Does black wire from service box go to terminal #1 and black wire to water heater to terminal #2? Does neutral (white) from service box go to terminal #3 and neutral (white) to...


WH40 is 240Volt timer.
WH40 will not work with 120V circuit.

See WH40 wiring illustration at following link:
http://waterheatertimer.org/How-to-wire-EH40-hot-water-heater-timer.html

There are two hot wires in 240V circuit because every circuit requires two wires to complete the circuit.
Hot wires from breaker connect to terminal 1 and 3.
Notice that small white wires are also connected to terminals 1 and 3.
Small white wires power clock motor located on back of mechanism, so this says power from breaker box must arrive on terminals 1 and 3. This insures that clock motor runs continuously.
If clock motor only runs when manual override switch is clicked ON, then your Hot and Load wires are reversed.

Bare ground wire connects to green ground screw.
Wires going to Load (water heater) connect to terminals 2 and 4.

FYI: Terminal A is not used unless circuit also has a Neutral wire,
See basic water heater circuit Diagram #2:
http://waterheatertimer.org/240-v-water-heater-circuit.html

Terminal A is also used if you want to convert WH40 to 120V timer by replacing 240V clock with 120V clock.

Refrigeration ynit not going into defrost, I need a electrical wiring diagram to help me troubleshoot this one. Where can I get that?


See defrost timers and wiring diagrams and manuals
http://waterheatertimer.org/Paragon-timers-and-manuals.html#defrost

You posted under 8145-20

8145-20 is time initiated, temperature or pressure terminated.
Defrost timer training pdf

The 8145-20 timer:
Power leads connect to terminals 1 and N.
For 120Volt circuit: L is black hot wire to terminal 1, N is white neutral wire to terminal N
For 240Volt circuit: L1 and L2 are the hot leads from 240V breaker

geno_3245_192.jpg
'NO' means normally open, so terminal 3 turns ON only when timer turns on (that is 'time initiated')
So the hot gas valve for defrosting is connected to terminal 3 and turns ON when timer turns ON.
The other wire from hot gas valve connects to terminal N where it completes the circuit

'NC' means normally closed, so terminal 4 is ON at all times EXCEPT when timer turns ON.
That means fan is ON all the time, except when time initiated sequence begins, and then fan turns OFF while hot gas valve is defrosting unit.
The other wire from fan connects to terminal N where it completes the circuit

The cycle limit switch is connected to terminal X.
This is the switch that terminates the defrost sequence and turns timer OFF
Other wire from cycle limit switch connects to terminal N where it completes the circuit

I also suggest you ask a paid fixya experts who can provide additional information by phone.
Paid experts will not answer your question unless they know the answer, and if their answer is not complete, then fixya offers money back guarantee.

I have a Et 70115C Intermatic Timer, I want to install it on my Hot Water Heater, I have connected the 2 110V leads from my breaker to Terminals 1 & 2 and connected the two leads from the hot water...


A) 5 terminal ET70115C.
Voltage selector set to 240.

B) BUT you say you have 120Volts from breaker >>> confusing, so I'm proceeding on basis that you meant to say 240V from breaker.
Add a comment at any time.

C) Review timer:
5-terminal ET70115 timer has NO and NC terminals
NC is normally closed >> this terminal has power when timer is OFF
NO is normally open >> this terminals has power when timer turns ON
For water heater, you want NO terminal 4 so water heater turns ON when timer turns ON

D) Wire for 240Volt water heater

Two hot wires from breaker connect to terminals 1 and 2. This powers timer clock.
Jumper wire connects between terminal 2 to terminal 3. This sends power to the switch circuit.
Wires to water heater connect to terminals 1 and 4

E) 5-terminal timer turns off 1 hot wire to 240V water heater.
Turning off 1 hot wire will stop 240V circuit from working; Water heater thermostats also turn off one hot wire.
240V water heater has black and red wire.
Wire from terminal 4 should connect to Black wire on water heater.

Diagram shows two wires on terminal 1
Two wires on terminal 2
One jumper wire on terminal 3
One wire on terminal 4
Zero wires on terminal 5

HP Probook 6560b BIOS doesn't recognize working WD SATA HDD. I have verified that it works in another computer and two other SATA HDD's work in my Probook. I have a WD Black 500GB SATA HDD (model #WD5000BPKX) that was the Kubuntu OS drive in my old HP Probook 6550b and works flawlessly when I test it in my husband's HP DV2000, but the BIOS on my current HP Probook 6560b does not recognize it. Running a HD test within the BIOS returns no drive installed, however booting from Ubuntu 16.04 and 18.04 Live USB sticks shows the HDD in the OS's file manager and partition manager, and another (Seagate) SATA HDD works flawlessly in this laptop. I have restored the BIOS to defaults and the version showing within the BIOS - F08 - is newer than the one shown for Linux on HP's driver site. Are you aware of any incompatibility with this particular model of HDD? I have VirtualBox but no Windows computer, if it is advised to update the BIOS to the current F67 revision shown for Windows computers on the HP support site. EDIT: Solved. I had no access to a Windows computer, but figured for whatever reason the BIOS in a computer that shipped with a 500GB SATA HDD wasn't recognizing a 500GB SATA HDD. So I installed the original Windows Vista Basic on the older 320GB HDD, downloaded the current HP BIOS update for that OS (on my husband's Ubuntu computer, since of course Windows didn't recognize all of my hardware), copied it to the 320GB HDD, and installed it without a hitch. The Probook 6560b is now running under a fresh install of Kubuntu 18.04 on the 500GB SATA HDD that wasn't recongnized prior to that update. Maybe not the simplest way to resolve it, but at least it's fixed. Hope this helps someone else with an older laptop not recognizing their SATA HDD. :)
