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

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

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>
