T460/461/T462 Manual 26th Sept 2008. V2.79 Part B © JED Microprocessors Pty Ltd 3
Projectors with same codes mentioned in the file R5975236_08 are BD2100, BD3000, BD3100, BD3200, BD3300,
BD5000, BD5100, BD8000, BD8100, BG8200, BG9200.
(Some models do not appear to have audio facilities in the projector, although the tested BR6300 does.)
What connections are made to inputs depends on input boards plugged into slots in the front of the projector, and when that slot
is functional, a box on the projected image identifies the input card and slot number quite clearly. Unused slots are also
indicated when selected. So when setting up, run through the available channels and name them appropriately in the “source”
selection setup screen.
Communications runs at 9600 8N1.

Don’t forget to set all unused T460 channels to “Skip” to jump over blank/unused inputs in all the above tables.
RS232 Connection for Barco
We don’t have a specific connection diagram for these Barco projectors, but one tested projector has a DB9 Male on the
projector. Only TX, RX and Ground were used for the test. (CTS was NOT needed). We assume this is the same for other
models. Use a multimeter to determine the TX connection (-9 volts) and connect to the RX in of the T460 (J6 Pin 3). Use
multimeter with the projector OFF in “resistance” mode and look for another line with approximately 5k ohm to ground, and
assume this is the projector RS232 input and connect to J6 pin 2 of the T460.
BenQ projectors: MP610, MP620, MP622/622C and MP720b, MP721/c, MP770
Note: for BenQ SP820 see: Optoma: EP771/772/774
These units, as shipped from BenQ, need to have the RS232 interface enabled and baud rate set to 19200 to interface with the
T460 controller. At the moment, this can only be done through the “secret” Factory Setup screen. These functions are currently
NOT available by pressing the MENU button on the projector.
We have been requested by BenQ not to include this information (on how to get into the Factory Setup) on our web site or
user’s manual; hence this is included in a separate document available on request from JED via our normal email address.
Note: This above setup procedure must have the projector firmware version that includes baud rate setting. If your
projector does not include the baud setting item contact your nearest BenQ service provider to have the firmware
upgraded. Go to www.BenQ.com.au to find the closest repair agent. Communications runs at 19200 8N1.
It is recommended to run always run these projectors in “Reply” mode.
It is also necessary to disable the projector’s “Source Scan” function (so the projector does not wonder off to other
sources is there is no feed to an input at the time it is selected, or if an input drops out, eg at the end of a tape or a
computer reboot). To do this disable, use the normal menu system;
1. Press the “Menu / Down (arrow)” or “Menu / Exit” key once;
2. Use the “Right (arrow)” key or “Left (arrow)” key to get to the drop-down menu with “Source Scan” as the 2
nd
/3rd item.
(On the MP622, this is called “Quick Auto Search”, by itself in the menu labelled “Source”;
3. Use the “Down (arrow) / Menu” key to highlight the “Source Scan” or “Quick Auto Search” item;
4. Use the “Left (arrow)” key to turn “Source Scan” OFF;
5. Press “Exit” or “Menu / Exit” key several times to clear the menu.
