4.3.4 Normal mode

Under normal operation, the receiver sends over the serial output the serial number and the key number of the
remote control received over the radio link. The format of the ASCII frame received is as follows:
:<serial number> <Key number> <CR><LF>
• : (ASCII code 0x3A)
• Serial number is the serial number of the remote control in decimal format (1 to 8 figures).
• Followed by a space (ASCII code 0x20).
• Key number is the number of the key pressed on the remote control (2 figures from 01 for key 1 to 24 for key
24).
• CR (ASCII code 0x0D), LF (ASCII code 0x0A)

5. «OEM» receiver ARF7293
The radio receiver ARF7293 converts the radio signal from a remote control. The ARF7293 sends information
from the remote control on the serial link and/or can manage 4 outputs.
This is a unidirectional system: the system behaves like 4 links where, for example, digital output 1 corresponds
to input 1 (key 1 on the remote control), digital output 2 to input 2 (key 2 of the remote control), etc.
The serial output is constantly available. The 4 digital outputs are available after a training phase. The outputs
can operate in monostable mode (closed when the remote control key is pressed) or in bistable mode (the posi-
tion changes each time the corresponding key on the remote control is pressed). The module comprises several
inputs dedicated to the choice of training mode and the choice between monostable and bistable output configu-
rations.
The ARF7293's parameters can be updated (serial link, programming mode, output mode...) using AT commands
via the serial link. With an appropriate serial adapter, the module can be connected to an RS232 cable.
