Remote Control Panels
Up to 10 remote control panels may be connected to the OG-RTR module.
Sierra Video offers an extensive line of RS-485 XY and single-bus remote control panels.
The connector on the rear module is a 3-pin male mini-XLR connector. The mating
connectors used are Switchcraft TA3F.
There are 2 connectors on the rear of the remote control panels that are connected in
parallel. This allows the panels to be looped (“daisy chained”) together. If it is more
convenient, you can build a fan-out panel or box so that only one cable needs to run to
each panel.
The maximum system cable length is 2,000 feet (310m) when the RS-485 network
operates at the higher speed of 31.25K baud. The maximum system cable length is 5,000
feet (1,524m) when operated at 9600 baud. Consult your Control Panel Manual for more
detailed information.
If you make your own interconnect cables, Pin 2 is Ground. Pin 1 and 3 connect pin for
pin.
Control via 9-pin Connectors
The 9-pin connector on the rear module allows you to control the routing switcher via an
external computer. On some switcher models, the serial port can be changed internally
for RS422 configuration (RS232 @ 9600 baud is factory configuration).
Each routing switcher model has one port and it is labeled on the back panel as
“RS232/422 Control” (refer also to the illustrations of back panels shown in Chapter 1):
Connection to the RS-232/422 port is made using a standard 9 pin (pin to pin) cable.
RS-232 pinout;
Pin 2……….TX
Pin 3……….RX
Pin 5……….GND
NOTE:
To convert the 9-pin connector to an RS422 serial port, contact Sierra Video.
