How I can transfer my files from a Acterna 5100E OTDR to my laptop? It only has a standard internal flash drive and 9 pin output. I have the original software.


This devices interface is extremely old technology the 9 pin connector is most likely a rs232 serial interface . If your laptop has a 9 pin rs232 interface you may need a DTE to DCE adapter .
if you do not have this old rs232 port on your laptop I think this device a usb to null modem rs232 DB9 Serial DCS Adapter Cable with FTDI.

from my reading of the manual a null modem may be needed

Usb rs232 cable


The USB socket shouldn't need a driver for that. USB means Universal Serial Bus. So it will accept almost any device. If there is an issue, find the USB to RS232 web site and download a driver from there, if one is available.

Symbol Model LS 9208, Bar code Scanner loaded factory setting, its scans(beeps) but does not display /show in the notepad.


If the scanner is connected through USB connection, the barcode should appear in the Notepad. If you use the Serial connection RS232, the Barcode data are showed than in Hyperterminal or other application, which is interpreting data from Serial Port.
Please scan the barcode from Product Guide according to your connection. And check the scanned data in an application - Notepad for Keyboard Wedge or USB, Hyperterminal for RS232.

I'm sure you have fixed your printer by now... but reflash the printer.

Flash memory is contained in SIMMs (single in-line memory modules) located
on the controller board. Printer emulation and operating system software are
loaded into flash memory at the factory, but you will install software in some
situations:
• The customer buys the PGL or VGL graphics, Expansion-CT, or IPDS
option after the printer is installed
• The customer needs to upgrade printer software
• The customer needs different emulation software
• You have replaced the controller board
• You have added or replaced the flash memory SIMM
Emulation and operating system software are stored as a compressed file on
a 3.5 inch floppy diskette. This file is “executable.” You will expand it and copy
it into printer flash memory.
You can load software through the serial, parallel, or Ethernet port of the
printer.
1. If the printer has an Ethernet interface, refer to the PrintNet User’s Manual
for the download instructions. You are finished with this procedure. If you
are going to load memory through the serial or parallel port, continue with
this procedure.
2. Make a printout of all saved configurations. (Refer to the User’s Manual.)
(Installing new software erases all saved configurations. You will use the
printouts to restore printer configuration.)
3. Set the printer power switch to O (off).
4. If the printer is already connected to the serial or parallel port of a
computer capable of running an MS-DOS® based PKZIP® self-extracting
file, go to step 11. If not, go to step 5.
5. Unplug the AC power cord from the printer.
6. Disconnect all data input cables from the printer interfaces.
7. Connect a parallel data cable to the LPT1 port or a serial data cable to the
COM1 port of an IBM-compatible computer that is using the PC-DOS™ or
MS-DOS operating system.
NOTE: You can connect the cable to the LPT2 port if the LPT1 port is alreadyin use. The load commands are different if you use this port, as
described in the note after step 18.
8. Connect the data cable to the appropriate I/O port of the printer.
9. Plug the AC power cord into the printer.
10. Power on the computer.
11. Insert the emulation or upgrade diskette into diskette drive A (or B) of the
computer.
12. Make the diskette drive the active drive by typing the following at the DOS
prompt:
A:<return> (If the diskette is in drive B, type B:<return>)
13. Get the name of the compressed file on the diskette by listing the
contents of the diskette; at the DOS prompt type:
DIR<return>
The compressed file on the diskette takes the form FILENAME.EXE
Now write down the complete name of the file with the .EXE extension.
14. On the printer control panel, press and hold down the ON LINE + PAPER
ADVANCE keys. Without releasing the keys, power the printer on.
Continue holding the ON LINE and PAPER ADVANCE keys down for five
seconds, then release them.
NOTE: The port default is CENTRONICS; this is the standard load through
the parallel port. If you want to use the default, continue at step 18.
15. When you see “WAITING FOR PROGRAM DOWNLOAD” on the LCD,
press the < (NEXT) key. “SELECT DOWNLOAD PORT =
DATAPRODUCT” appears on the LCD.
16. Press < (NEXT) again to cycle through the download ports available in
the printer:
DATAPRODUCT (parallel)
CENTRONICS* (parallel) (default port)
RS232-9600 (RS-232 serial, 9600 baud)
RS232-19.2K (RS-232 serial, 19200 baud)
RS232-38.4K (RS-232 serial, 38400 baud)
RS232-115K (RS-232 serial, 115000 baud)
RS422-9600 (RS-422 serial, 9600 baud)
RS422-19.2 (RS-422 serial, 19200 baud)
RS422-38.4K (RS-422 serial, 38400 baud)
RS422-115K (RS-422 serial, 115000 baud)
17. When the printer download port you want to use is displayed on the LCD,
press ENTER. “WAITING DOWNLOAD / PORT = <your selection>
appears on the display.
18. At the DOS prompt on the computer type:
FILENAME.EXE -pb<return>
where FILENAME.EXE is the compressed file you noted in step 13. This
command decompresses the file on the diskette and copies it as a binary
file into the flash memory on the printer controller board.
NOTE: If you are loading the file using the LPT2 port on the computer, enter
the following DOS command:
FILENAME.EXE -pb 2 <Return>
The 9600 baud rate is the only selection older versions of DOS can
use. The baud rate information entered in the following DOS
commands must match the selection you made in step 16.
the load process and status. (LCD messages are listed in Table 2,
page 37.)
CAUTION Do not interrupt the downloading process once it has started.
Interrupting a download will damage the flash memory on the controller
board and PrintNet card ( if installed).
19. When the new program has successfully loaded into memory and the
printer has reset itself, set the printer power switch to O (off).
20. Unplug the AC power cord from the printer.
21. Remove the diskette from the computer and store it with the printer.

Projector Serial Port Codes


Hi there

They might be the same if the Projectors are from the same series.

First figure out if the RS232 codes are in ASCII or HEX. You will most probably be using the HEX codes.

Best would be to contact the dealer you bought this unit from - they should by all means be able to help you out.

What is the right rs232 cable to connect a Denon 3808CI reciever and a Phillips RFX9600 serial extender


OK LOOKING AT THE SPECS FOR THE EXTENDER YOU DO NOT NEED TO WORRY ABOUT THE SERIAL CONNECTIONS, WHEN USING THE SERIAL CONNECTIONS YOU NEED RS232 CODE STRINGS TO CONTROL THE DENON OR ANYOTHER DEVICE THROUGH THIS EXTENDER USING THE RS232 CONNECTIONS.
IT LOOKS LIKE YOU CONNECT AN I/R EMITTER FROM AN MINI JACK I/R CONTROL PORT ON THE BACK AND THE OTHER END TO THE I/R WINDOW ON THE DENON
