(6) DB9 male, bidirectional RS-232/422/485 ports. Up to 115.2k
baud, hardware and software handshaking support. Ports C-F
support C2N-NPA8 Network Poll Accelerator8.
PIN DIRECTION DESCRIPTION
1* To AV2 or PRO2 (RXD-) RS-422 Receive Data (Idles low)
2 To AV2 or PRO2 (RXD) RS-232 Received Data
3 From AV2 or PRO2 (TXD) RS-232 Transmitted Data
4 From AV2 or PRO2 (TXD+) RS-422 Transmit Data (Idles high)
5 RS-232 and RS-422 Signal Common
6 To AV2 or PRO2 (RXD+) RS-422 Receive Data (Idles high)
7 From AV2 or PRO2 (RTS) RS-232 Request to Send
8 To AV2 or PRO2 (CTS) RS-232 Clear to Send
9 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) IEC Socket, mates with removable power cord (included).
19 CHASSIS GROUND
(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.
