RS-422 differential serial data
The 320E units transport differential data signals with compatible
Full Duplex RS-422 type devices. Note that RS-422 does not
support handshaking control signals. Use the following steps
when connecting data transmission equipment:

1.

Connect your serial data cable to the user’s RS-422 device.
(See Figure 2-6).

2.

Repeat step 1 for the 320E RX unit.

Figure 2-8 shows pin connections between the 320E Series
