STANDARD SETTING OF THE KEY FOB'S BUTTONS POSITION 9 TO 10
Each push-button of the keyfob switches on and off one of the four channels independently.
1st and 2nd channel [9-2] standard work: From start position press and release <S2> switch 8 times and then <S1> switch once.
3rd and 4th channel [10-2] standard work: From start position press and release <S2> switch 9 times and then <S1> switch once.
RESET (stopping channel work) POSITION 11 TO 14
Channel 1 [11-1] To stop 1st channel from working: From start position press and release <S2> switch 10 times and then <S1> switch twice.
Channel 2 [12-1] To stop 2nd channel from working: From start position press and release <S2> switch 11 times and then <S1> switch twice.
Channel 3 [13-1] To stop 3rd channel from working: From start position press and release <S2> switch 12 times and then <S1> switch twice.
Channel 4 [14-1] To stop 4th channel from working: From start position press and release <S2> switch 13 times and then <S1> switch twice.
Each channel has one Trigger/Reset input. This input can be set as a Reset and respond to ground pulse for longer than 0,2 sec.
If channel is set up on bistable mode, giving signal RESET for that channel will stop the channel working. Signals twice on the output
“S”.
If channel is set up on monostable mode, giving signal RESET for that channel will stop the channel working with out signalisation on the output
“S”.
TRIGGER (start channels work) POSITION 11 TO 14
Channel 1 [11-2] To start the 1st channel: From start position press and release <S2> switch 10 times and then <S1> switch once.
Channel 2 [12-2] To start the 2nd channel: From start position press and release <S2> switch 11 times and then <S1> switch once.
Channel 3 [13-2] To start the 3rd channel: From start position press and release <S2> switch 12 times and then <S1> switch once.
Channel 4 [14-2] To start the 4th channel: From start position press and release <S2> switch 13 times and then <S1> switch once.
IMPORTANT! TRIGGER / RESET SOFTWARE SERVICES FOR CHANNELS FROM 1 TO 4
Channels from 1 to 4 have a TRIGGER/RESET input. These 4 inputs responds to electric signals of a lower value than 1,3 VDC and time longer than 0,2
sec.This entry may occur from a supply VDC from 0 to 50 VDC. If above +5 VDC power supply occurs, the diodes will provide a voltage cut-off. Thanks to
that solution the device will not be damaged. This input can be set as a TRIGGER. Low level supply signal with time min. 0,2 sec. on input 1 can cause
switching of channel 1 (signalling once on the output
“S”).
If input is still on low level after impulse generation has been set, the system will not extend the
time. Next minus impulse (low) on TRIGGER/RESET input with time 0,2 sec will cause extended monostable impulse. Inputs TRIGGER and RESET have
two states; as low state - supply from 1,3VDC and as high state - supply above 3,5VDC.
MONOSTABLE START - STOP (time registration for monostable mode) POSITION 15 TO 18
Channel 1 [15] Time registration for channel 1: From start position press and release <S2> switch 14 times. Then hold <S1> switch. This will start the
time recording. Releasing this switch will finish the recording.
Channel 2 [16] Time registration for channel 2: From start position press and release <S2> switch 15 times. Then hold <S1> switch. This will start the
time recording. Releasing this switch will finish the recording.
Channel 3 [17] Time registration for channel 3: From start position press and release <S2> switch 16 times. Then hold <S1> switch. This will start the
time recording. Releasing this switch will finish the recording.
Channel 4 [18] Time registration for channel 4: From start position press and release <S2> switch 17 times. Then hold <S1> switch. This will start the
time recording. Releasing this switch will finish the recording.
Signalling low battery level of the key fob Controller’s software is registering each press of the key fob in order to check the level of the usage of the
battery. If the battery is low (about 10V)
there will be 6 signals on the
“S”
output. After that signalisation system begins it's normal operation.

First black wire - antenna do not cut! This wire should be left hanging free. Do not connect or group with other wires. It has a direct influence on the
functioning of the key fob transmitter.
