Connecting The Serial Interface Cable - Epson EPL-7500 User Manual

Connecting the Printer to Your Computer
Connecting a serial interface cable
The EPL-7500 has two serial channels, one wired to a 25-pin
connector, and the other to an S-pin
(RS-232)
either of which can be used for conventional asynchronous serial
communication.
If you want to use one of the printer's serial interfaces, make sure
that you have a properly shielded cable and that it is the correct
one for your computer and the EPL-7500. Be sure to change the
SelecType Level 2 INTERFACE setting to the serial mode you want
to use before you connect the interface. Save the new setting with
the SAVE LEVEL 2 option. See Chapter 3 for instructions on
changing SelecType settings.
Connecting the RS-232 serial interface cable
Follow these steps to connect the RS-232 serial interface cable:
Turn off both the printer and computer. Then unplug the
1.
power cord from the electrical outlet.
2. Plug the cable connector securely into the CH S2 serial interface
as shown below.
