UHBX-R-XT
5.0 Serial Commands
The UHBX-R-XT will be communicating with a host through its HDBaseT
input at a fixed baud rate of 9600 and no parity.
Command
Response
Function
XCn <cr>
XCn <cr>
Connect the host controller to a specific unit addressed by n.
n = 01 - 99 or * (for all)
If n is not specified, the unit reports an address of the unit
connected to the host controller
XT <cr>
XT <cr>
Transmit serial command from RS-232 port. This command should
be followed by a string of serial bytes to be sent out, and it is
terminated by two single bytes hex 17 and hex 0D
If you want to include Hex bytes in your string (mixed with ASCII),
define hex bytes with &h before the two digit number
Example:
XT <cr>
(tells the receiver to get ready to receive command bytes)
HELLO WORLD&h0d
(this is the string that will be sent out)
Hex 17 Hex 0D
(send the command above. Of course you need to find out
how to send hex 17 and hex 0D through the HDBaseT sender. If a PC’s serial
port is used, you can press Ctrl+w for hex 17 and Enter for hex 0D)
XR <cr> x Bytes Read the response received at the RS-232 port. There is a 64 byte
receive FIFO on the RS232 port. Reading will also clear FIFO
XBn <cr> XBn <cr> Set baud rate for the local RS232 port.
n = 1, 2, 3, 4, 5, 6, 7, 8 correspond respectively to
baud = 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200
XPn <cr> XPn <cr> Set parity for the RS232 port. n = 0,1,2 (None, Odd, and Even)
XSn <cr> XSn <cr> Send stored serial command out the RS232 port (n=1 - 6).
AMn <cr> AMn <cr> Set auto mode
n = 0 – 1 = Manual – Auto
ODn <cr>
ODn <cr>
Set auto off delay
n = 0 – 240 (in minutes)
FD <cr>
FD <cr>
Perform a factory default.
FW <cr>
FWx.x <cr>
Read firmware version.
NOTE:
If n is not specified in any of the commands above, the command becomes a query command
instead of a set command. In response to a query command, the system reports the current status of that
command.
