3.   Power on the controller and initialize the newly 
connected UHF radio board.
4.  e UHF radio uses the same frequency as the base 
radio. Both Rx and TX are on the same frequency. 
An FCC or IC license is required to operate the UHF 
radio. If the base network is on the internet through an 
Ethernet gateway, the “CLOUD ID” will be displayed 
on the controller faceplate. Communication at the 
Central can be veried by sending test commands via 
the Sentinel WMS or Laguna software and looking for 
acknowledgment.
