Change Serial Port Settings
To make changes to the serial port settings (i.e. Baud Rate), select the “Serial” tab.
The “refresh” button will re-read the current settings in the routing switcher.
Make any changes necessary and press “Save” to implement changes.
Note:
Routing switcher must be reset for changes to take effect. You will be prompted to reset the
routing switcher. If you do not reset the routing switcher at this time you must remember to do so
later by removing and re-applying the power.
*When controlling an external routing switcher the 9-pin serial connection must be a “null
modem” cable.
Mode
The serial port has two mode settings, “Master” and “Slave”. In the “Master” mode the
serial port is used to control external devices (layers). In the “Slave” mode the routing
switcher can be controlled via the serial port by an external device (i.e. automation) and
set to respond to either Sierra Video or Kramer protocol.
With Sierra Video protocol, you can choose to have the router acknowledge commands
(Respond Always), or to be silent (Respond Never).
