Indicate identifier in the display, command „A“ (41h)
This command less parameters as a broadcast command (address/identifier=99) will make every networked
SPA indicate the device-specific identifier in the bottom line of the display. The upper line is blind.
This command is a desginated broadcast command.

01h 83h 41h 04h 80h
Response Not confirmed
The SPA remains in this mode until being switched off and on again or until transmission of another command.
Extended identifier command „AX“ (41h,58h)
This extended command is utilized for addressing individual multicon devices in the bus network in a similar
way as described above. By broadcast command the identifier to be assigned is transmitted to all networked
devices as follows:
SOH Adr Cmd Sub identifier = 01 EOT CRC
Transmission
01h 83h 41h 58h 30h 31h 04h 40h
Response Not confirmed
Similar to standard command all devices now show the identifier just transmitted and that is to be assigned in
the upper line. Entering the identifier is proceeded the same way. However contrary to the above no
confirmatory command „B“ will be replied. It is up to master to check whether the identifier has been accepted,
for example by command “R” (read current value). The R-command is transmitted under the corresponding
identifier to the position display. If the addressed SPA is responding the assignment was successful and the
master can proceed with the next identifier. Regarding other commands the display of the respective device
switches to standard operation.

4.5.1. SPA profile reset, command „K“ (4Bh)
This command is deleting all previously programmed profiles.
Example 1: Profile reset at specific N 141

01h 20h 4Bh 7Fh 04h C6h
SOH Adr Data EOT CRC

01h 20h 6Fh 04h 52h Device replies by standard response ‚o’ (6Fh) = OK
Example 2: Profile reset at all N 141 by broadcast command (Identifier=99)
SOH Adr Cmd Data EOT CRC
Transmission
01h 83h 4Bh 7Fh 04h DBh
Response Not confirmed
Important: After profile reset all profile data are set to auf FFFFFFhex , the current profile number to FFhex.
The display now shows 6 dashes instead of the target.
