Selecting the rear panel Remote port protocol and baud rate
N The Remote port settings are protected when front panel Lock mode 2 is
selected. You can view the settings in Lock mode 2 but you cannot adjust them
from the front panel. See “Setting the front panel locks ( Executive modes)” on
page 3-40.
N This procedure works for the rear panel Remote port only. The front panel
Config port’s protocol can be changed via SIS command control only. See the
Command/Response table for SIS commands, in chapter 4, “Programmer’s
Guide”, to configure both ports under SIS control.
The switcher’s rear panel Remote port can support either RS-232 or RS-422 serial
communication protocol, and can operate at 9600, 19200, 38400, and 115200 baud
rates. The settings of these variables can be viewed and changed from the front
panel.
View and configure the switcher’s remote port’s serial communications settings as
follows:
1 . To enter Serial Port and Audio/RS-232 Input Configuration mode, simultaneously
press and hold all Control buttons (Enter, Preset, View, and Esc) (figure 3-63).
ENTER PRESET VIEW ESC VIDEO AUDIO
CONTROL
ENTER PRESET VIEW ESC
CONTROL I/O
The flashing Control LED indicates the baud rate as follows:
Enter — 9600 Preset — 19200
View — 38400 Esc — 115200
The flashing I/O LED indicates the protocol as follows:
Video — RS-232 Audio — RS-422
In this example, the port is set to RS-232 at 9600 baud.
Press and hold the Enter, Preset, View, and Esc buttons.

All Control LEDs light with one flashing. Both I/O LEDs light
with one flashing.
Serial Port and Audio/RS-232 Input
Configuration mode also provides a way to
view and change the TP inputs’ secondary
inputs (RS-232 or audio). See “Defining
the Audio/RS-232 wire pair” in this chapter. NOTE

2 . Release the Control buttons.
N If front panel Lock mode 2 is selected and you try to perform step 3, the actions
are ignored; and the Enter, Video, and Audio LEDs flash. See “Setting the front
panel locks (
Executive modes)” on page 3-40.
