Earth
The controller contains several layers of protection against induced high voltage
transients from static discharge, lightning, and power line spikes. In order for this
protection to be fully effective, a good connection to earth ground is essential. Wire this
connection to a metal cold water pipe or similar structure. Do not connect directly to the
AC earth. Use 16 AWG or heavier cable and keep the length as short as possible (
less
than 50 feet [15 meters] ).
For multiple panels always use only a single point ground reference for all panels. Bring
the shields of all reader and communication cables back to one location. Do not connect
them to the panel or the panel‟s housing.
DIP Switch Settings
The URC-2000‟s DIP switches control a number of operating parameters including the
device address and serial port baud rate. The controller must be powered down to accept
any changes in the DIP switch settings. Use DIP switches one through five to set the
controller address. Switches six and seven set the communication baud rate, and switch
eight is used to set the connection type (
modem or direct) .
