RS-422 differential serial data
The 235 transmits differential data signals compatible with Full
Duplex RS-422 electrical signals. Note that the RS-422 does
not support handshaking control signals. Use the following
steps for data transmission.
1.
For the near-end, label and connect one serial computer
data cable to the user’s RS-422 device.
2.
Connect the other end of this cable to the front panel RS-422
female pin connector on the 235.
3.
At the far-end, label and connect one serial computer data
cable to the remote RS-422 device.
4.
Connect the other end of this cable to the front panel RS-422
terminal block connector on the far-end 235 unit.
Figure 2-7 shows pin connections between the 235 unit (as a
DTE unit) and the user’s RS-422 device (as a DCE unit).
