Model SC1080-H

4. Serial Control

The video input selection and signal parameter settings for the SC1080-
H can be controlled via an external control system by using the RS-232
port on the unit.

Use a straight thru M/F DB9 serial cable to connect the unit to the PC.
Only the TX, RX and GND pins are implemented in the connector. The
RS232 port operates at 19200 baud, no parity and 1 stop bit. In
response to a valid command, the SC1080-H will respond with CR, LF,
>, SPACE and then the listed response. Commands may be entered as
uppercase or lowercase.

With most commands, the SC1080-H will reply immediately, but other
commands may take a few seconds to complete. The user must wait for
the full response before issuing more commands to the unit.

For Example

Sending a POWER ON Command (“S POWER 1”) results in the
following response from the SC1080-H:

SENT

53 20 50 4F 57 45 52 20 31 0D

S P O W E R 1 CR

RECEIVED

0D 0A 3E 20 50 4F 57 45 52 20 4F 4E 0D 0A

CR LF > P O W E R O N CR LF

The unit must be powered on with either the front panel push button or
by sending the POWER ON Command before the unit will respond as
listed. Sending any commands with the unit powered off will result in the
following response from the unit.

Please turn on power. ( K POWER / S POWER ON ).
