CHAPTER 5: RS-232 CONTROL
Set the COM number, bound rate, data bit, stop bit, and parity bit parameters correctly, and the commands are ready to send in the
Command Sending Area.
5.2 RS-232 COMMAND FORMAT
Each unit in a cascaded system must have a unique ID if using RS-232 control. Using the ID PRESET DIP switch, set the ID. For
example, the unit ID of the first splitter is set as 0, and then the second is set as 1 and so on.
The system supports RS-232 pass-through control; if the RS-232 IN port is connected to a PC, and the others are connected to
third-party devices, these third-party devices can be controlled by following these steps:
1. Send the command in the format below to select the unit to receive commands.
FIGURE 5-1. COMMAND FORMAT
2. Send the specific control command data (HEX) to control the selected third-party devices. For specific commands, refer to the
user manuals of the devices you want to control. For example, send A5 A5 A5 5A 01 WW 02 0A 01 00 RR to mute the third-party
devices.
SWITCHING ON/OFF HDBASET OUTPUTS
The HDBaseT outputs can be controlled by sending commands. Connect the PC to the RS-232 input, and then according to the next
steps to switch on/off HDBaseT outputs.
Take the unit ID of 2, for example.
1. First, send F5 BB 6F 20 to select the unit to receive commands.
2. Second, according to the format shown, send the command to switch on/off HDBaseT outputs.
FIGURE 5-2. COMMAND EXAMPLE
If the HDBT 1 port needs to be turned on, other ports are closed, send the command AB AC BC 10 00.
