Notes:
1. Row 25 is physically at the top of the connector in its “normal” orientation; Row 1 is at the bottom. Looking
from the front of the rack, Column Z is on the left; Column F is on the right.
2. The RxD/, CTS, TxD/, and RTS lines are standard RS-232 signals. The inputs are only used if jumpers E17
and E18 each connect their pins 1 and 2. The DSR and DTR lines are simply shorted together.
3. The RD-, RD+, SD-, SD+, CS+, CS-, RS+, and RS- lines are standard RS-422 signals. The inputs are only
used if jumpers E17 and E18 each connect their pins 2 and 3.
4. The SERVO-, SERVO+, PHASE- and PHASE+ clock lines are at RS-422 levels. These signals are outputs if
jumper E1A connects its pins 1 and 2; they are inputs if jumper E1A connects pins 2 and 3.
5. The AuxRxD/, AuxCTS, AuxTxD/, and AuxRTS lines are standard RS-232 signals. These signals are
provided only if the Option 9T auxiliary serial port is ordered. The AuxDSR and AuxDTR lines are simply
shorted together.
6. The USBDP(D+) and USBDM(D-) signals are standard USB signals. They are only provided if the Option
1A USB interface is ordered.
7. The EthTxF+, EthTxF-, EthRxF+, and EthRxF- signals are standard Ethernet signals. They are only provided
if the Option 1 Ethernet interface is ordered.
8. The WD_NO (normally open), WD_COM (common) and WD_NC (normally closed) lines are the outputs of
the watchdog-timer hard-contact relay. The normally open contact is only conducting to common if the card is
powered and operating correctly. The normally closed contact is only conducting to common if the card is not
powered or the watchdog timer has tripped.
