Serial Output
The Receiver outputs serial data in ASCII 8-bit decimal format
(each ASCII character is represented by eight bits). Serial data
has a different format than Wiegand data (see below) and data
is always unbuffered – that is, every Tag read is output. Serial
data has the following format by default:
R R R A A A F F F T T T T T LF CR
R = Receiver ID number
A = Activator ID number
F = facility code
T = Tag ID number
LF = Line Feed (in hex, 0A)
CR = Carriage Return (in hex, 0D)
If the Receiver has been configured to interface with older
systems, then the output has the following format:
A A A F F F T T T T T LF CR
Wiring TTL Outputs to TTL Outputs
A terminal block and leads for activating two TTL outputs are
provided with the Network Receiver.
To wire TTL output to TTL outputs
1. Remove the receiving antenna.
2. Remove the nut at the base of the receiving antenna BNC
connector.
3. Gently open the case.
4. Place the terminal block on the J9 header (Figure 16). Run the
wires out the provided hole in the Receiver case. The wires have a
knot tied to provide strain relief.
