From AV2 or PRO2
(TXD-) RS-422 Transmit Data (Idles low)
* RS-422 transmit and receive are balanced signals requiring two lines
plus a ground in each direction. RXD+ and TXD+ should idle high (going
low at start of data transmission). RXD- and TXD- should idle low (going
high at start of data transmission). If necessary, RXD+/RXD- and
TXD+/TXD- may be swapped to maintain correct signal levels.

(1) 6-32 screw, chassis ground lug.
1. Interface connectors for NET, Infrared-Serial, I/O and Relay Output ports are provided with the unit.
2. This LED was labeled “ERR” on units manufactured prior to 2005. It is functionally the same; only the labeling has changed.
3. PRO2
only.
4. LAN LEDs are active only if a single port or dual port Ethernet card (which is field installed) occupies the Z-Bus slot.
