Epson Epson - Manual (Page 27)

Note
If you use ECP mode (Extended Capabilities Port), check
your parallel device software documentation for the correct
DMA channel (DRQ) setting. Then set jumpers JP8 and JP18
to match this setting if necessary. See “Changing the Jumper
Settings” in Chapter 4 for more information.
Using
the serial port
If you have a printer, a modem, or other device with a serial
interface, you can connect it to one of the serial (RS-232C) ports.
Make sure you have a cable compatible with a DB-9P connector.
To connect a serial device, insert the connector into
either of the two serial ports, which are marked with
the icons shown at the left. If you are connecting only
one serial device, use the serial 1 port.
Connecting the Power Cord
Follow these steps to connect the computer’s power cord:
1. Plug the power cord into the power inlet on the back of the
computer. Note that the position of the power inlet and AC
outlet on your computer may be reversed.
