5.8.3.3 Firmware Version / Unit ID (F)
The command for obtaining device information is issued in the form
hexadecimal: 02 XX XX 46 03 XX
content: <STX> <address> F <ETX> <checksum>
e.g. for a device with the device address 11 connected to the serial port
hexadecimal: 02 31 31 46 03 47
content: <STX> <address=11> F <ETX> <checksum>
The positive response to this command returns a message containing
 the firmware version, e.g. G.01
 the protocol version, here always 2.15
 the model number, here DEV1953
 the size (input ports x output ports) of the "matrix", here always 032X016
In the message, the firmware version (v), the protocol version (Pv) and the model
number are separated by "space" (<sp>) characters, the size is separated from the
model number via a slash ("/").
A DEV 1953 that is connected via Ethernet with firmware version G.01 returns

The command for querying the switch status of an output port ooo has the form
hexadecimal: 02 XX XX 4F XX XX XX 03 XX
content: <STX> <address> O <output ooo> <ETX> <checksum>
e.g. for a device that is connected via Ethernet the switch status request for output
port 1 is
hexadecimal: 02 46 46 4F 30 30 31 03 7F
content: <STX> <address=FF> O <output=001> <ETX> <checksum>
The positive response to this command is
hexadecimal: 06 XX XX 4F XX XX XX 03 XX
content: <ACK> <address> O <input iii> <ETX> <checksum>
e.g. for a device that is connected via Ethernet if the queried output port is
connected to input port 2
hexadecimal: 06 46 46 4F 30 30 32 03 78
content: <ACK> <address=FF> O <input=002> <ETX> <checksum>
