RS232 connections to Sanyo, Eiki, Christie LX25, 32, 37, 45 and some Philips

There are three types of connectors used on these families of projectors, and rather than list them here by projector (over 100

types) it is simpler to just list the three connection schemes, and then allow users to choose one from the three tables for the

appropriate connector after physically examining the projector of checking the projector user manual. 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.

While it does not appear that CTS is ever needed on almost all projectors in this family, some list it on DIN8, Pin 5, and

IT IS DEFINITELY NEEDED ON THE NEWER PLC-SC/XC10 MODELS. We hence recommend that all installations

actually wire this line in, to allow for what may be a future trend in this family as projectors are updated.

This is a completely non-typical projector from Sanyo, using different connectors, hex codes (BE EF etc), etc.

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.

4 34h DIN-4 S-Video S-Video

5 33h 3-RCA component Component

The “Input search” function MUST be disabled.

Audio is limited: there is only one stereo RCA input, and NO audio output. There is control (incremental, 0->100 NOT 0->60

as the manual says) via the RS232 control, but only to the rather weak internal speaker. Use a T461 if better audio is needed.

Freeze and mute (pic and sound) are supported, but toggle only with the “Freeze/Mute” keyboard, but no 2-yellow-button mute

is provided with a “Volume” keyboard as the projector codes cannot command absolutely or read back the mute state.
