Host Mode
Series 12 and 8 routing switchers have one 9-pin RS232 connector that allow you to control the
switcher using a standard personal computer or other external devices (such as Creston or AMX).
The switchers are shipped in the “Host” mode but 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 RS232/422 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.
Power Up
Once all signal and control connections have been made, turn on the power switch. AC to the
router is indicated by a illuminated power switch button. If you have power up problems ensure
that the AC fuse on the back of the switcher is seated properly.
On power up, the controller will restore the routing switcher to the last state it was in before the
power was turned off including all configuration settings as well as crosspoint switcher status.
