Front Panel Cabling

To connect the host device to the config port
on the front panel, use the optional Extron
female 9-pin D to 2.5 mm TRS Configuration
Cable. The same port is also used to provide
control using the SPPCP.
The pin configuration is shown in figure 9.

RS-232 (rear panel) — The video scalers accept SIS commands from a host device such as
a computer running the Extron DataViewer utility or other control system. Control commands
can be sent through this port or the Config port on the front panel (see "Front Panel
Cabling").

This RS-232 port can also be used to provide control by the SPPCP. For more information
about controlling these video scalers, see
Processing Products Control Program
NOTES:
The wiring in the RS-232 cables must cross over so that the transmit port of the
•
control device connects with the receive port of the video converter and vice versa.
Only one serial port can be used at a time. If the front port is in use, the rear captive
•
screw connector must be disconnected from the computer or other control device.
Likewise, if the captive screw port is in use, the Config port on the front panel must
be disconnected from the computer or other control device.
