EDN25C. Two DB25-female-to-RJ-45-female adapters pinned as in
Figure 3-1 should be connected to the EDDC, one at each end. Our
product code for these adapters is FA081-R2. Cable running from the
Converters’ serial ports to these modular adapters could be the two flat
satin cables that came with your units. If your system consistently garbles
transmissions or loses data, however, you might have to replace the flat
satin with two short lengths of modular UTP (the cable specified in the
previous paragraph).

P Converter (128K) system, follow
the steps listed in
Section 3.2.1
if you’re using a single Converter or those

P
Converter’s serial (RJ-45 female) port to the RJ-45 female serial port on:
• your serial device (if it has one),
• the appropriate adapter for a serial device that has a different type of
serial port (see Figure 3-3), or
• an RJ-45-female-to-DB25-female adapter pinned as in Figure 3-1
(FA081-R2) to convert to EDDC for a long cable run.
3A. If you haven’t already, complete the link from the Converter to your
serial device:
• If you’re running flat satin/UTP, plug the adapter into the device’s
serial port.
