Front Panel Cabling

To connect the host device to the config port on the front panel, use
the optional Extron 9-pin D female to 2.5 mm TRS Configuration
Cable (part #70-335-01). The same port is also used to provide control
using the SPPCP.
The pin configuration is shown in the figure and table below.

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

The same port can also be used to provide control by the SPPCP. For more information
about controlling these video scalers, see the section on
"Software and Firmware".
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.
