Remote RS‑232 Control
Use a female 9-pin D connector to bare wire RS-232 cable or a universal control cable
(UC50' or UC100') to connect your computer or control system to the Remote RS-232 port
(see figure 6, left, to wire this Remote connector for RS-232).
1.
Wire the unterminated end of the RS-232 cable to the three pins of the 3-pole captive
screw connector, starting at the left of the 3-pole captive screw connector:
a.
Connect the transmit wire from the RS-232 device into the Rx pin of the switcher.
b.
Connect the receive wire from the RS-232 device into the Tx pin of the switcher.
c.
Connect the ground wire from the RS-232 device into the G pin of the switcher.
2.
Plug the 3-pole connector into the Remote port on the rear panel of the switcher.
3.
Connect the other end of the cable to the appropriate computer or control system port.
Figure 6.
Over TP RS‑232 and IR Control
Use a female 9-pin D connector to bare wire RS-232 cable or a universal control cable
(UC50' or UC100') to connect your computer or control system to the Over TP RS-232 and
IR port (see figure 6, right, to wire this 5-pole connector).
1.
Wire the unterminated end of the RS-232 cable to the first three pins on the 5-pole
captive screw connector, starting at the left:
a.
Connect the transmit wire from the RS-232 device into the Rx pin on the switcher.
b.
Connect the receive wire from the RS-232 device into the Tx pin on the switcher.
c.
Connect the ground wire from the RS-232 device into the G pin on the switcher.
2.
Wire the unterminated end of the IR cable to the third, fourth, and fifth pins of the
5-pole captive screw connector:
a.
Connect the transmit wire from the IR device into the Rx pin on the switcher.
b.
Connect the receive wire from the IR device into the Tx pin on the switcher.
c.
Connect the ground wire from the IR device into the G pin on the switcher.
3.
Plug the 5-pole connector into the Over TP port on the rear panel of the switcher.
4.
Connect the other end of the cable to the appropriate computer or control system port.
NOTES:
•
The RS-232 and IR connectors share the ground pole and the data from both can
be transmitted simultaneously.
•
The IR Tx and Rx line pairs and the RS-232 Tx and Rx line pairs must each cross
once between their connectors and the source or destination.
•
The length and preparation of exposed wires is important (see the wiring
