Radio Link Channel Analysis Procedure
The procedure of analysis of radio link channels is to be run by pressing the combination “two
short presses and one long press” on the program button S2 (see Figure 3-1). The analysis
procedure takes four minutes, ARR32 indication being as follows: POWER and LOOP are off, RADIO
flashes with green and amber alternately four times per second.
The procedure of analysis of radio channels can be run from a personal computer using S2000R
Configurator (see Section 7).
In the process of analysis the ARR32 selects the RF channel with the least load. When the procedure
has been completed the ARR32 automatically starts operating on the selected channel and saves this
channel as a default channel for auto mode.
If the analysis procedure was not employed, the Channel 0 is considered to be a default auto channel.
If necessary, the analysis procedure can be aborted by short simultaneously presses on the program
button S2 and the tamper switch S1.
While analyzing the radio frequency channels the ARR32 stops communicating with
radio link devices.
