Adder Technology 2XPRO ユーザーズマニュアル

You can switch the SmartView XPro remotely by sending RS232 data to the serial
communications port (located on the rear panel adjacent to the power connectors).
All data should be sent using the following RS232 protocol.

No handshaking is implemented but valid command characters will be echoed back
to the sender.

The top nibble (4 bits) of the command byte defines the user port that is to be
switched (1=port 1, 2=port 2, 3=port 3 and 4=port 4). The bottom nibble defines the
computer port that the user port is to be switched to (e.g. 0=port 1, 1=port 2, E=port
15, F=port 16).

For example:

Hexadecimal code 

14 switches user port 1 to computer port 5

Hexadecimal code 

38 switches user port 3 to computer port 9

Hexadecimal code 

4D switches user port 4 to computer port 14

Special codes are:

Hexadecimal code 

71 switches user port 1 to computer port 0 (off)

Hexadecimal code 

72 switches user port 2 to computer port 0 (off)

Hexadecimal code 

73 switches user port 3 to computer port 0 (off)

Hexadecimal code 

74 switches user port 4 to computer port 0 (off)
