T460/461/T462 Manual 26th Sept 2008. V2.79 Part B © JED Microprocessors Pty Ltd

Note: We have seen both options for pins 1 and 2. Check with a multimeter, and the projector output (called “RX” in the above

table) will have –5 to –9 volts on it. Acer PD523PD and Optoma EP706, EP708S, EP709, EP712E, EP719H EP780, EP810,

EP910 DS309, DX609, EP752, EP761, EP763, EP721, EP723, EP727, and EP728, definitely use pin 2 (above) as an input.

After installation wiring of any projector to a T460, use a multimeter to check voltages on BOTH TX and RX pins.

Panasonic projectors

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:

Note: Quite a few Panasonic projectors need an address setup. This software assumes an address of 00.

Models that need this are: PT- D3500/4000/5500/5600/5700/7500/7600/7700/10000, PT-DW500/5000/5100/7000/10000,

PT-L520,PT-L785, PT-L6500/6510/6600. (On several other types, we have not been able to determine whether this is needed.

Please check PT-LB20/30, PT-D995, PT-L5, PT-L555/556/557/757/758 and PT-LC50, and let JED know results. If any of

these undetermined ones need address mode, set FLAG7=1 to use addressing format.)

Don’t forget to set all unused T460 channels to “Skip” to jump over blank/unused inputs. Turn off auto-source.

Also, note the PT-L390 uses a non-standard incremental audio volume control, so the current code cannot drive this projector

audio. Use a T461 in the mean time.

The PT-AE900/AE1000/AE2000/AX100/AX200, PT-D4000/5500/5600/5700/7500/7600/7700 and PT-DW5000/DW5100/

DW7000/DW10000 have no audio system, so use a T461 if you need audio. (Some others may not, either.)

Use a Freeze/mute or Mute On/Mute Off keyboard only with these, unless a T461 is used. The PT-AE900/AE1000/AX100

(and maybe more models) support aspect ratio using the dummy channel “4:3/16:9/Zm.” (“VS1”)

Several Panasonic projectors do not process Mute (Shutter) or Freeze commands.
