Serial Control Ports
The internal control CPU processor has three serial ports for Terminal and/or Host protocol
control. These three serial ports are used for overall routing switcher system personalities, local
or networked PC computer control, and control panel network operation. Terminal Protocol is a
human-readable protocol while Host Protocol is a machine-friendly protocol. The three serial
ports are shipped with a factory default as described below;

Connections to the 9-pin can be made using a standard one- to-one cable. Pin functions are
described below.
Host Mode
The Ponderosa matrix switchers have three 9-pin RS-232/422 connectors that allow you to
control the switcher using a standard personal computer or other external devices (such as
Creston or AMX). Serial ports shipped in the “Host” mode can be changed to the “Terminal” mode
by the following procedure:
 Connect a terminal to the serial port and send the following command:
**HOST0!!
The port now uses the terminal protocol.
 To restore back to the Host port, send the following command:
**HOST1!!
Terminal Mode
The 9-pin connector labeled RS-232/422 Control can be used for simple terminal control,
(V=T100 emulation capability). The terminal performs the following functions:
 Serves as an overall system controller
 Sets up the personality of the entire system (size, level control, change names,
mapping, etc.)
These setups are stored in non-volatile memory so that a terminal is not required unless it is
necessary to change a setup.
