e.g.:
Command
GET(1;Input)
Response DATA(1;Input;0)
Query the current input source for display 1. Current Input Source is Display
Port.
SAVE(ID;ALL
)
ID = Display address
Command
SAVE(1;ALL)
Response ACK(1)
Values are automatically saved after change. Due to different internal
processor design, this separate SAVE command is obsolete. For compatibility,
it’s still implemented and ACK(ID) will be returned always.
Broadcast
Sending commands using ID=0 is a broadcast to all connected devices. Use
carefully to avoid unintended overwriting of existing values. Flow control
needs to be implemented by control system, using ACK reply estimation.
e.g.:
Command
GET(0;Input)
Response DATA(1;Input;0)DATA(2;Input;1)….
Command
SET(0;Input;0)
Response ACK(1)ACK(2)ACK(3)
Remarks
For the Power-Command the behaviour of the broadcast command differs
from the Power-Command for individual devices. A SET(0;Power;0) will set all
devices to deep-sleep mode. In this mode communication with individual
devices is not possible, especially the Power-Command sent to and individual
ID behind the master device will not work. Please use SET(0;Power;1) to power
on the entire wall again.
