Taxan Kaga- Plus projector families: (Code 40..43) KG-PV-131S/X/Xh,

KG-PS-232X/Xh

Channel codes are:

Input1 := '#SA' + 0D + 0A;

Input2 := '#SB' + 0D + 0A;

Input3 := '#SV' + 0D + 0A;

Input4 := '#SS' + 0D + 0A;

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, making S-Video the video default. Setting OPT5 will

swap Computer1 and Computer2. Setting OPT4 will allow double- presses on some keyboards.).

• OPT7 handshake mode and power on connection blink codes available;

• Turn off the auto-source feature;

• Freeze and blank (toggle) are supported (keyboard code A), and any non-volume keyboard; and

• Absolute mute is not supported, so even if using a T441/461, absolute video mute is not available.

RS232 connections to Kaga -Taxan - Plus projectors

These use a 9-pin-D9 male on the projector, female on cable. Comms is at 19200 baud, 8 bits, no parity, 1 stop.

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.

Baud rate change

This family of projectors can be operated at 115,200 baud or 19,200 baud. As shipped from Kaga/Taxan,

communications is at 115,200 baud, and must be set to 19,200 for use with a T440 to get reasonable wiring length.

A built-in baud rate changer is incorporated as dummy channels in the T430/T440, using codes 41 hex and 42

hex. In operation, selecting code 43 hex will control the projector at 115200 (not recommended for install). Use 40 hex

for install to run at 19200 baud.

Switch to 19,200 as follows:

Wire to the projector via a short cable (in the workshop). Set code 43 hex and verify the projector operates ok at 115200

baud (One red blink then steady, On, Off, channels working OK)

Set a projector code of address of 41 hex, and reset the T440 with the reset switch.

The red OFF LED will come on steady.

Press the/an ON button. The #CL<CR><LF> baud rate change command is sent to the projector.

Set a projector code of 40 hex, and reset the T440 with the reset switch. Check the operation at 19200: (One red blink

then steady, On, Off, channels working OK) It is ready for use.

(If the projector needs to be reset to operate at 115200, set code 42 hex and reset the T40. The red OFF let will come on

steady. Press the/an ON button. The #CH<CR><LF> baud rate change command is sent to the projector.

Set code 43 hex and Reset the T440, and verify the projector operates ok at 115200 baud (One red blink then steady,

On, Off, channels working OK) The baud rate is held in projector non-volatile memory, so the baud rate setting to

19,200 need be done only once.
