SHASTA HD 88 HD/SDI 3G ROUTING SWITCHER

Control via 9-pin Connectors

The 9-pin connectors allow you to control the routing switcher via an external computer.

On some switcher models, the serial port can be changed internally for RS422

configuration (RS232 @ 9600 baud is factory configuration).

Each routing switcher model has one port and it is labeled on the back panel as

“RS232/422 Control” (refer also to the illustrations of back panels shown in Chapter 1):

Connection to the RS-232/422 port is made using a standard 9 pin (pin to pin) cable.

RS-232 pinout;

Pin 2……….TX

Pin 3……….RX

Pin 5……….GND

NOTE:

To convert the 9-pin connector to an RS422 serial port, contact Sierra Video.

Control via Ethernet

The matrix switches may be controlled via Ethernet using the Host Protocol. To control

the matrix switcher, establish a TCP/IP connection to the IP addresses of the routing

matrix using port number 10001. A communications program such as Hyper Access can

be used to establish this connection. Once the connection is established, sending the

command **!! should cause the routing matrix to return ** OK !!. This connection

supports the entire Sierra Video Host protocol command set.

Host Mode

The matrix switchers have one 9-pin RS232 connector that allows 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.
