4K Pro 4×4 HDMI®
True Matrix
PN 15378 < RS-232 GUIDE
INTRODUCTIONThis Blackbird™ device can be controlled by a computer using an RS-232 serial connection and by issuing commands using RS-232 control software.
CONNECTIONThis device includes a DB-9 male to female RS-232 serial cable, which is used to connect your PC to the matrix. If your PC lacks a DB-9 serial port, you will need to use a USB to Serial adapter cable (available separately P/N 3726).
RS-232 GUI CONTROLThis device includes software, which allows you to directly control it using either an Ethernet or RS-232 connection. Simply copy MatrixController.exe to your PC and doubleclick the file to launch it. Note that the EDID® Selector on the side panel must be set to 1111 to allow for PC control.

RS-232 COMMAND CONTROL
Rather than GUI control, you can also issue direct commands using a third party RS-232 control software package, such as CommWatch.exe, whose interface is depicted below.
Set the communications parameters to the following:
5
Baud Rate: 19200Data Bits: 8Stop Bits: 1Parity Bits: None
RS-232 COMMANDS
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.
ChecksumMany of the following commands require that a checksum be included as part of the command. This ensures that the 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 SwitchingThe following command allows you 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.
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.

Receive Package: A5 5B 01 05 01 00 FF 00 00 00 00 00 FA
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 FF in the Receive Package indicates that HPD is Low. It will change to 00 if the HPD status is High.
