RS232 connections to Optoma Group 1 projectors: Use the three-pin DIN wiring diagram below.

Data in is on pin 2 (RXD) Comms is at 9600 8N1

RS232 connections to Optoma Group 2: EP776, EP782 projector with D9

These use a 9-pin-D9 male on the proj, female on cable. Comms is at 9600 baud, 8 bits, no parity, 1 stop. Note: This is

opposite to the Optoma D9 wiring below!!

After installation wiring of any projector to a T460, 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 3: EP706, EP708S, EP709, EP712E, EP719H

The following table shows the mapping of T460 channel number, the string sent, and the input associated with that channel in

the manual, and how it is identified on the on-screen menu. No audio in provided, so use a T461 if audio control needed:

T460 Channel TX code Input name in manual Function as identified on screen

1 ID00IR021 VGA RGB/YPbPr/YCbCr/SCART VGA (1)

2 ID00IR022 D-SUB 2 VGA2 (EP719 only)

3 ID00IR024 Composite Video VIDEO

4 ID00IR023 S-Video S-VIDEO

5 ID00IR020 DVI-D DVI (EP709, EP712, EP719H only)

Don’t forget to set all unused T460 channels to “Skip” to jump over blank/unused inputs. 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.)

Note: Aspect ratio control is included. Use source names: “Set small4:3”, “Set reg 4:3” and “Set reg 16:9”.

Note: MuteOn/Mute Off and Freeze On/Off and Mute On/Off keyboards are supported, and work normally. If a Volume

keyboard is used, a T461 is needed.

Note: Coms is at 9600 8N1. Optoma EP706, EP708S, EP709, EP712E, EP719H definitely use pin 2 (above) as an input, in the

three-pin DIN wiring diagram below.
