RS-422 differential serial data
The Mini-HDMI-AD transmits one (1) channel of differential data
signals compatible with Full Duplex RS-422 electrical signals.
Note that RS-422 option is factory set and is not a standard
configuration. The RS-422 does not support handshaking
control signals. Use the following steps for RS-422
transmission.
1. For the near-end, label and connect one data cable to the
user’s RS-422 device.
2. Connect the other end of this cable to the front panel RS-422
terminal block connector on the Mini-HDMI-AD (see
Figure 2-5).
