Converting & Testing Codes

The codes shown on pages 3-6 are raw hex codes and must be converted to the appropriate format in order to work with proprietary controllers such as those from Crestron or AMX. To help with the conversion, here are two sample strings for those brands:

Crestron controller – Power On Command:

\x21\x89\x01\x50\x57\x31\x0A\r

AMX controller – Power On Command:

SEND_STRING dvProj, "$21, $89, $01, $50, $57, $31, $0A”

You can see from these examples that it is easy to convert any of the RS-232C codes in this guide into the equivalent Crestron or AMX control strings. This should also be the case for most other controllers that allow transmission of hex data.

In order to test these commands, it is useful to have a program that can send raw hex codes directly to the Serial port on a PC. There are many programs that can do this, but there are a few that are useful for test purposes:

RS232 Hex Com Tool – 30 Day Evaluation Version avai lable from http://www.rs232pro.com This is a very simple to use program that lets you send any hex command and see the response from the projector. The Evaluation Version times out every five minutes, but it can be instantly restarted and is very simple to use.

Hercules Setup Utility – Free from:

http://www.hw-group.com/products/hercules/index_en.html

This is a slightly more complex program that can do far more than just send hex commands. Use the “Serial” tab to send commands direct to the serial port. This program is recommended if you are a more experienced PC user.

Docklight – Evaluation version available from: http ://www.docklight.de

Another more advanced program. This one is particularly good for checking the Acknowledgement Response Return Codes.

AccessPort – Free from: http://www.sudt.com/en/ap/ index.html

This is an intermediate level program. Not as easy to use as some of the others, but free.

Eltima Software Advanced Serial Port Terminal – 14 Day Evaluation Version available from: http://www.eltima.com/products/serial-port-terminal/

This is an excellent intermediate level program. It allows the commands to be sent in loops for repeated testing. It also shows the return codes in both hex and ASCII formats.

If you want to use just one program from those above for general testing, I would recommend the Hercules Setup Utility.

All of these programs will accept the hex codes exactly as shown in this guide. They can simply be copied and pasted into the programs and then sent to the projector. Most of the programs require the user to switch to hex mode before sending hex codes.

Please note that you will require a cross-connected serial cable (sometimes called a null- modem or DTE/DTE cable) if you wish to connect the projector to a PC for testing.
