Appendix A—Extron Switcher Interface to Model 100

In addition, all Extron switchers must be configured to use HJT protocols and 19200 baud rate (Hughes-JVC emulation). This is usually done at Extron and a “Configured for Hughes-JVC” sticker is placed on the back of the unit. The Extron Service Manual for each unit describes how to reset the system to a state compatible with the HJT protocol, if necessary.

A.2 Extron User’s Manual Inaccuracies

Early revisions (up to Rev C) of the Extron Model 8 and 10 User’s Manual, describe incorrect configuration procedures for setting Master mode. Specifically, the description shows that when switch 4 of the address switch block is set to the closed position it enables the configuration mode. The correct position for this switch is the opened position. A correct example for setting the Model 8 and 10 switchers is detailed below.

A.3 Key Operational Differences Between Models

The switcher firmware for Model 8 and 10+ function differently from the Model 4 firmware. Switching on the Model 8 and 10+ always occurs independently of the projector. For example, when a channel switch is pressed on the Model 8 and 10+, the switcher automatically selects that channel after a short time period (~2 seconds). This channel switching occurs even if a projector is not connected to a switcher. When a projector is connected to a Model 8 or 10+ (and the communication interface is working properly) and a channel switch is pressed, the projector normally changes the channel immediately (before the 2-second time period has expired).

On the Model 4LD, there is no automatic channel switching. Channel switching is prohibited unless commanded by the projector. If the communication interface between the switcher and projector is not functioning properly, no channel switching occurs.

A.3.1 Switcher to Projector Configuration Example

The following provides an example of how to configure an Extron Model 8 Switcher to a HJT Model 100 Projector:

1.Connect the switcher to the Model 100, Port B.

2.Set Comm. Setup to Port B.

3.Set the Port B baud rate to 19200.

4.Turn power off at the remote control (or PC).

5.Wait at least one (1) minute, for the system to reach an “Off” state from Step 4, then toggle the circuit breaker on the rear panel to Off and then back to On.

6.Verify that the Model 8 Switcher internal dip switches are set to Hughes Emulation and the baud rate is set to 19200

(use the Extron manual to confirm this).

7.Turn power on to the Model 8 Switcher.

8.Set the Model 8 external “address” dip switch #4 to the open position.
