Plus 9 volt CTS/DTR to projector
After installation wiring of any projector to a T440, use a multimeter to check voltages of –9 on BOTH TX and RX pins
in any installation, as described in the troubleshooting part of this manual.
Optoma Group 7: EP706, EP708S, EP709, EP712E, EP719H (Code 0B hex)
Channel allocations are as follows:
Input1 := 'ID00IR021';
Input2 := 'ID00IR022';
Input3 := 'ID00IR024';
Input4 := 'ID00IR023';
Input5 := 'ID00IR021';
Any one of these codes can be set into Constant:0/Constant:1 for computer codes and Constant:2/Constant:3 for video
codes. (The default is to have Computer1 (above) as the "Computer" channel and Video1 as the "Video" channel.
Setting OPT1 switch ON will swap Video1 and Video2 channels.)
This projector has no audio so use a T441/T461 if audio control needed.
•
Absolute freeze and mute commands are available so a code A keyboard works OK
•
If OPT4 is enabled with a code 0, 0 or A keyboard, two computer and two video channels can be allocated.
•
NO power on panel connection blink codes or OPT7 handshake modes are available.
•
The "Source Lock" option in the "Management-I" menu MUST be turned ON (to stop the projector searching for
•
other channels when an input is dropped.)
