RS-232 SERIAL INTERFACE CONNECT a PC or CONTROL SYSTEM
The Shinybow switcher can be controlled via the RS-232 serial control port to
allow for interfacing to a PC, or similar third party control system.
The serial communication parameters are 9600 baud, 8 bit, No Parity and 1
stop bit - this is often referred to as 9600 8N1. When the unit recognizes a
complete command it will perform the requested action - there is no delimiter
character required.
The unit does not send out a message when a value is changed from the front panel or by IR control.
If the unit needs to be controlled via the front panel in addition to the RS-232 control, you should
regularly poll the unit status to ensure the control system accurately reflects the current settings.

MORE STUFF FOR SB-4140
Note: Turning the unit System Power Off over RS-232 will
extinguish the LED channel display leaving only the Power
switch LED on. The Video and Audio outputs will also mute.
While the unit is turned off by RS-232 it will continue to accept
and act upon switching commands. For example, if the unit is in
the off mode (via RS-232) and you send a command to switch
an input to an output, that route will complete and the video and
audio will now appear on that channel only. The front panel LED
channel display for that particular output will also show the input
selected (for that single output channel only). The remaining
LED’s will remain off and video and audio outputs muted. The
unit will still return status and change messages in response to
commands sent while in Power Off state. A hard reset command
(SBALLRST)will return the unit to normal operation and also
unlock the front panel.
