Port 1 (Terminal Port)
Yosemite routing switchers have two 9-pin RS232 connectors that allow you to control the switcher using
a standard personal computer or other external devices (such as Creston or AMX). Port 1 is shipped with
Terminal protocol mode set as default. A 9-pin connector labeled “RS232/422 Port 1”, located above the
sync input reference mains, is used for a simple terminal (V=T100 emulation capability). Port 1 in
Terminal mode has these main functions:
 Serves as overall system controller
 Sets up and view the personality of the entire system (size, level control, change names,
mapping, etc.)
These functions are stored in non-volatile memory on the master processor so that a terminal is not
required unless it is necessary to change a setup.
Connections to the 9-pin are shown in the table below. “Transmit” and “Receive” refer to what is inside
the system. Connect to the opposite function at your end.
