URC2000
Connection Details
Power
The URC-2000 requires 9 to 14 volts DC and draws about 200ma.
PC Interface
The PC interface connects the URC-2000 to a PC through an RS485 (2-wire) connection.
Inputs
There are two common terminals for each set of inputs (one between inputs one and two,
another between three and four). Seven different input types are supported (including
normally open, normally closed, one resistor, and two resistor configurations).
Outputs
Two of the four programmable outputs are dry contact relays (UL rated 2A @ 30v dc).
These are designated as outputs one, and three. The other two outputs are solid-state
switches (open collector to ground capable of sinking 100ma).
Readers
Readers are connected to non-programmable outputs BUZ, & LED, as well as data inputs
D0 and D1. Both readers have their own connection terminals, reader A is designated as
P4 and reader B is designated as P5.
