Jumper Link Setting
There are three Jumper Links which may be used to configure the following
Link Open Fitted
WDOG Watchdog OFF Watchdog Active
MODE LORA Mode 3 LORA Mode 7
MOM/LAT Momentary Latching
WDOG - WATCHDOG
This provides improved reliability and security useful in with electrically noisy Loads.
When the WDOG link is fitted each MAINSLINKPRO automatically sends a background watch-
dog RF signal and expects to receive a corresponding WDOG signal from its partner.
If the WDOG signal is not received within 90seconds, the output will drop out and comms LED
will flash.
MODE
LORA Mode 3, Faster operation shorter range (Line of sight upto 3Km/500m in buildings)
This mode is recommended for general operation,
LORA Mode 7, Slower operation Long range (Line of sight upto 5Km/1Km in buildings)
This mode can be used where additional RF penetration / range is required
Note! In this mode a transmitted signal can take 2 seconds to trigger the receiver.
MOM/LAT - Momentary or Latching
Sets the Relay changeover contacts to operate as Momentary or Latching.
MOMENATRY: used for MAINSLINKPRO TO MAINSLINKPRO
LATCHING: Select this when MAINSLINNPRO is controlled by a Remote transmitter.

Switching Lower Power LED Lights
MainslinkPRO incorporates a “snubber” protection circuit
which is recommended with Load connections such as a Mo-
tor or pump.
If MAINSLINKPRO is being used to switch lower power LED
lighting the snubber circuit can cause the LED lights to
faintly glow.
To remove the snubber, remove Jumper link J2 is on the
rear of the PCB (as image shows)
