RS 422 Differential Serial Data
The 260E 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 2-5).
2. Connect the other end of this cable to the front
panel RS-422 female terminal block connector of
the 260E TX unit.
3. Repeat step 1 and 2 for the 260E RX unit.
Figure 2-6 (b) shows pin connections between the 260E
Series unit (as a DCE unit) and the user’s RS-422
device (as a DTE unit).
