Instructions (cont…)
To set the E-Key receiver links
Send an SMS message to the EKRXGSM in the following format:
password:L(abcde)
•
a
is the fifth link with 1 indicating the link is fitted and 0 indicating the link is not fitted
•
b
is the forth link with 1 indicating the link is fitted and 0 indicating the link is not fitted
•
c
is the third link with 1 indicating the link is fitted and 0 indicating the link is not fitted
•
d
is the second link with 1 indicating the link is fitted and 0 indicating the link is not fitted
•
e
is the first link with 1 indicating the link is fitted and 0 indicating the link is not fitted
The meaning of each link corresponds to the different E-Key receivers as follows:
EKRX42S / EKRX44S
•
a
FF
/
not used (set as 0 or 1)
•
b
L4
/
not used (set as 0 or 1)
•
c
L3
/
FF
•
d
L2
/
M2
•
e
L1
/
M1
Eg: Sending the SMS “Password:L(00011)” to an EKRXGSM connected to a EKRX42S receiver will act as if
the L1 and L2 links are fitted. This will enable E-Key buttons 1 and 2 to activate the first relay output in single
channel mode. (See the EKRX42S instructions for further options)
Eg: Sending the SMS “Password:L(10000)” to an EKRXGSM connected to a EKRX44S receiver will act as if
the FF link are fitted. This will enable E-Key buttons 1…4 to activate relays 1…4 respectively in four channel
mode with flip flop enabled. (See the EKRX44S instructions for further options)
To set the default button activation when receiving an incoming call
Send an SMS message to the EKRXGSM in the following format:
password:B(x)
•
x
is the required equivalent E-Key button number from 1…4 that is emulated when the EKRXGSM
receives a validated incoming call. The factory default setting is a left button or button 1 emulation
Eg: Sending the SMS “Password:B(3)” will cause the EKRXGSM to initiate the equivalent of an E-Key button
3 press when it receives a validated incoming phone call.
Alarm input connection
The NSGSM opto-isolated alarm input circuit is designed to accept various AC and DC input triggers ranging
from 5 to 48 Volts. The alarm active SMS is sent when the input detects the application of an applied voltage,
while the alarm reset SMS is sent when the input detects the removal of voltage. Care must be taken to
include a current limiting resistor in series with the voltage source with the resistance chosen in accordance
with the table:
