RS-232 Communications
Connecting the Cables
Connect the HomeBase to the host computer or other device by plugging an RS-232 serial cable into the
RS-232 Port
(see page
13-3) on the back panel. The wiring of your cable depends on whether the other device is set up as a Data Communications
Equipment (DCE) or Data Terminal Equipment (DTE) device.
The HomeBase communication port is configured as a DCE device. To communicate with a DCE device, use either a null modem
adapter in line with a standard RS-232 cable, or a null-modem serial cable. To communicate with a DTE device such as a PC,
use a standard (or straight-through) RS-232 cable.
You can make your own cables by following the pin configuration in the chart below. To do so, you must determine if your host
RS-232 device is 9-pin or 25-pin, and whether it is configured as a DCE or DTE device.
