LQ-300-2. Where can I get a connecting cable?


To connect to a PC, a network, what? According to Manual you can use a USB cable to your PC or a parallel cable. The Parallel cable plugs into to RS-232 connector on your PC if it has one. It looks like a Video connector plug but is about 1.5-2 inches long. You will need a RS-232 Cable to connect. It has a pin type connector on 1 end and a weird sort of connector on the other that looks like a plastic ridge with flat brass contacts on both sides. See Pics . First one is PC plug and second is Printer plug

Is there any way to interace with USB


You will need 3 items to interface your Wizard with a USB port.

1. A generic USB to RS-232 adapter cable (with 9-pin serial connector, to match the connector on the OZ-730 interface cable).

2. A USB to RS-232 driver for the above cable. (If you have Windows XP: HL-340.EXE, contained in 111.rar, which can be downloaded from www.usbserialdrivers.com. If you have another version of Windows, or if you have Linux, you will have to consult the documentation on www.usbserialdrivers.com to find the correct driver.

3. Software to communicate with the Wizard. You should be able to use the software that came with it, or purchase RuppLynx, or download Microsoft ActiveSync or a similar free program.

I used a cable I purchased on ebay, the HL-340.EXE driver installer, and RuppLynx software to connect an OZ-730, an OZ-570, and a Zaurus 5800 to my Windows XP laptop without any problem.

RS 232 cable manufacturer


Is 25 pin or 9 pin connector?
In either case pins 2 & 3 are Tx & Rx data, you might have to swap them.
On DB-9 pin 5 is GND, on DB-25, Pin 1 & 7 are GND.
Here is a link to a reliable source of pinouts for you to construct your cable.

Want to connect to my computer


What connector/interface does your PC has
9-pin or 25-pin connector

If it has 9-pin connector: use the following:
DB-9 RS-232 Serial Connection
or
DB-25 RS-232 Serial Connection

If it has 25-pin connector: use the following:
DB-25 Serial Connection
or
DB-25 RS-232 Serial Connection

If you are configuring the computer to use an RS-422A serial port, you need a special cable. Contact the computer or printer network manufacturer to see if an RS-422A cable is available. If no cable is available, contact your computer manufacturer for your computer pin assignments and have a cable constructed.

The default configuration for the serial port on the printer is for RS-232C serial communication. To set the printer to use RS-422A serial communication, change the control panel Serial Menu’s SERIAL setting to SERIAL=RS-422.

EPSON PHOTO PC 500 DIGITAL CAMERA


Serial meaning 2.5mm stereo headphone looking jack to DB9 or "atari joystick" looking plug? I had one on my first Toshiba PDR-M1 camera but that was like 9 years ago. You can probably find the pinouts online for that cable, I believe it is a standardized cable.

The stereo plug is wired to the PC serial port as shown in the following diagram:
tip ring sleeve +---------------------------------+
| |
/-------+-----+--------------+ |
| RxD | Gnd | TxD | 2.5 mm Stero Plug |
\-------+-----+--------------+ |
| |
DB9*: pin 2 pin 5 pin 3 +---------------------------------+

DB9*: Optionally short together pin 4 (DTR) to pin 6 (DSR) and
pin 7 (RTS) to pin 8 (CTS)
The following table also describes the camera cable's wiring: Camera PC's
Plug DB9* Signal Name Direction
---- ---- ----------- ---------
- 1 Carrier detect (CD) input to PC
tip 2 Receive data (RxD) input to PC
sleeve 3 Transmit data (TxD) output from PC
- 4 \ Data terminal ready (DTR) output from PC
ring 5 | Signal ground (Gnd) -
- 6 / Data set ready (DSR) input to PC
- 7 \ Request to send (RTS) output from PC
- 8 / Clear to send (CTS) input to PC
- 9 Ring indicator (RI) input to PC
* Note that the cable's D-subminature DB9 RS-232 serial port connector is female. This connector also goes by the historically more correct name of "DE-9J".
