Set the communications parameters to the following:

Baud Rate: 115200
Data Bits: 8
Stop Bits: 2
Parity Bits: None

RS-232 COMMANSD

The following commands are in hex, not ascii, so you should select the Hex Send Mode option in your command software before issuing commands. Note that each command is 13 bytes long.

Checksum

Many of the following commands require that a checksum be included as part of the command. This ensures that command is input correctly. The checksums must be  calculated in hex mode. We suggest you use a calculator with a hex mode option. Calculate the checksum using the following formula:

Checksum=0x100 – (0xa5+0x5b+0x02+0x03+input port+0x00+output port+0x00+0x00+0x00+0x00+0x00)

Port Switching

Issue the following command to switch the input for a given output.

0xa5+0x5b+0x02+0x03+input port(1~4)+0x00+output port(1~4)+0x00+0x00+0x00+0x00+0x00+checksum

For example, to set Output 2 to Input 1, issue the following command: A5 5B 02 03 02 00 01 00 00 00 00 00 F8

Port Query

Issue the following command to display which input is selected for a given output.

Send Package:            A5 5B 02 01 01 00 00 00 00 00 00 00 FC
Receive Package:         A5 5B 02 01 01 00 01 00 00 00 00 00 FB

The red 01 in the Send Package is the output port number. Replace it with a 02, 03, or 04 if you want to query a different output port.

The blue 01 in the Receive Package is the input port number. It will be 02, 03, or 04 if a different input port is connected.

ARC Set

The following command allows you to enable or disable ARC for a given output.

0xa5+0x5b+0x10+0x01+ARC (0x0f:ON;0xf0:OFF)+0x00+input port(1~4)+0x00+0x00+0x00+0x00+0x00+checksum

ARC Query

Issue the following command to display the ARC status for a given output.

Send Package:            A5 5B 10 02 00 00 input port(1~4)00 00 00 00 00 checksum

Receive Package:         A5 5B 10 02 F0 00 input port(1~4) 00 00 00 00 00 checksum The blue F0 indicates that ARC is off. It will be 0F if ARC is on.

EDID Set

The following command allows you to specify which EDID® to use from the internal EDID table for one or all inputs.

0xa5+0x5b+0x03+0x02+Edid index(1~15)+0x00+input port(0~4)+0x00+0x00+0x00+0x00+0x00+checksum

Note that using 00 for the input port indicates all inputs.
