Connecting for Serial Communication
The front panel Config ports on both the transmitter and the receiver (see
figure 5
,
B
,
on page 9 and
figure 6
,
B
, on page 10) enable communication with a computer via an
RS-232 connection. Connect a 9-pin D-to-2.5 mm cable from the host computer serial
port to the Config port on either the transmitter or receiver front panel to enable serial
communication (commands are sent to both units simultaneously). SIS commands can be
entered at the computer and issued to the transmitter or receiver through these ports to
control and configure the unit. The protocol for the ports is 9600 baud, 8 data bits, 1 stop
bit, and no parity.
An optional 9-pin D-to-2.5 mm TRS configuration cable is available from Extron and can
be used to connect your computer to this port. Figure 8 shows the configuration and pin
assignments of this cable.

Enabling and Disabling Peripheral Emulation
The transmitter can be set up to emulate a mouse and keyboard to the host computer that
is connected to the transmitter Host input port. This allows the computer to boot up in the
event that it requires a USB keyboard or mouse to be present.
When peripheral emulation is
disabled
, up to
four
USB hubs can be connected in a series
to the receiver. When peripheral emulation is
enabled
, up to
three
hubs can be connected.
Using Extron Simple Instruction Set (SIS) commands, you can disable and enable peripheral
emulation (by default, peripheral emulation is enabled). The following peripheral emulation
commands can be issued to the
transmitter only
:
•
To disable:
