Using Stand-Alone
Communication
Device
If sufficient signal strength cannot be achieved, take one of the following actions:
1. Try relocating the cabinet to an area with better reception.
2. If moving the cabinet cannot achieve sufficient signal strength, an external, stand-alone
communication device (ex. GSMV4G) can be used. Follow these steps:
a. Power down the control.
b. Remove the Internet cable from the RJ45 connector
(if connected) and disable the Internal IP/GSM
portion of the control board by moving the
Internal/External IP/GSM Jumper to the OFF pair
of pins.
c. Connect the communication device to the control’s
ECP terminals and complete all other
communication device wiring as required.
