5.6.3.3 System Identification (XR)
This command can be issued in order to obtain device information
<STX>XR<checksum><ETX> i.e. <STX>XRAA<ETX>
The device specific identification data is returned in the format
("⌡" and "⌠" are symbolizing that the two consecutive lines are actually one line)
<ACK><STX>XR:DEV<sp>SYSTEMTECHNIK,<model_number>,<model_type>,⌡
⌠<firmware_revision><checksum><ETX>
E.g. for a DEV 1951 with 2 switch modules and with firmware revision G.01
<ACK><STX>XR:DEV<sp>SYSTEMTECHNIK,DEV1951,2*AB-Switch,G.0155<ETX>
Note:
<sp> denotes the "space" character.
5.6.3.4 Read Status of Signal Path (S or SA)
This is the command for the query of the switching status of the device
<STX>S<checksum><ETX> i.e. <STX>S53<ETX>
or
<STX>SA<checksum><ETX> i.e. <STX>SA94<ETX>
The device answer is a (sequence of) three digit number(s each) indicating to which
input port the corresponding output port is connected to
<ACK><STX>S:o

} = ("{"and "}" indicate that the content only will be reported if two switch
modules are installed)
the input port number of the second switch module that is
001: second switch module / primary input port "In A" or
002: second switch module / secondary input port "In B"
if command set 1 is active;
OR
003: second switch module / primary input port "In A" or
004: second switch module / secondary input port "In B"
if command set 2 is active;
