Host Control Ports
The switcher has two serial ports and an Ethernet LAN port. Any of these ports can be
connected to a host device such as a computer running either the Extron DataViewer utility
or the HyperTerminal utility or a control system. These ports make control of the switcher
possible.
Serial Ports
The serial ports are:
•

The default protocol for both ports is as follows:
The ports can be configured to operate at the 9600, 19200, 38400, or 115200 baud rate.
