Appendix A. Extron Switcher Interface to Model 100

This appendix provides instructions on how to set up and configure the HJT Model 100 Projector for proper operation with Extron Switchers 10+, 8, and 4LD.

The baud rate for the Extron switchers is 19200. Since Port A is locked to a baud rate of 9600, Port B should be used for Extron Switchers. The projector port assignment must be selected and the VIC channel assignment must be edited for a switcher.

To select the Baud Rate:

1.From the MAIN MENU, select #7, SYSTEM, then #4, COMM. SETUP.

2.From the COMM. SETUP menu, select PORT B SPEED.

3.From the SPEED SELECTION LIST, select 19200.

4.Press ESCAPE to go back to the COMM. SETUP level.

To set the projector port assignment:

1.From the COMM. SETUP menu, select PORT B DEVICE.

2.From the DEVICE TYPE list, select #3, VIDEO SWITCHER.

3.Turn power OFF at the remote control.

4.Wait until the Arc Lamp fans have stopped running, and provide a system “cold boot” by toggling the circuit breaker on the projector rear panel to OFF, then back to ON.

To edit the VIC channel assignment (refer to Section 4.11 on page 4-39 for more information on editing):

1.From the CHANNELS list, select the channel to assign the switcher.

2.Press MODE. This is a toggle key that brings up a submenu for editing (pressing MODE again removes the submenu.)

3.Select EDIT from the submenu and press ENTER.

4.Use the right arrow key to toggle over to the third VIC column.

5.Press ENTER and use the up/down arrow keys to select the current switcher channel number. Press ENTER when the current switcher channel number is shown.

6.Press ESCAPE to exit the EDIT MODE.

A.1 Extron Switcher Configuration

The Extron switcher must have two (2) important parameters for it to work optimally. First, it must be in the “Master” mode. If in “Slave” mode, the display power and video mute buttons are internally inhibited. Second, it must receive a projector “Power On” message. This message is sent routinely during a projector “Power On” sequence. If the “Power On” message is not received due to cabling problems, baud rate problems, projector configuration, or switcher emulation problems, the video mute will not work properly.
