This Freedom device is tested to:
Electrical: UL294
EMI Radiation: FCC Part 15 Class B
INSTALLATION REQUIREMENTS
Freedom Bridges should only be installed in
dry
,
non-condensing
environments. The ambient temperature of the
environment should range between
-40°C
and
50°C
.
Freedom Encryption Bridges should only be mounted to
non-conductive
surfaces. Incorrect mounting may short-circuit
the electronics, which will cause it to malfunction.
DC power, reader, input contact, and output device wires should be between 16-28 AWG. They should also be stripped
5.5mm to sufficiently fit the terminal blocks and ensure that they do not come in contact with each other.
INSTALLATION PROCEDURE
For each of the following steps, be sure to reference the wiring diagram on page 2 for additional details:
1. Connect an
RS-485 Reader
to the
RS-485 Reader Input
on the Freedom Bridge.
The selection of 2-wire or 4-wire
operation is done via UDP configuration, as is the baud rate (nominally 57600)
a.
A 2-wire RS-485 reader must be connected with a 4-position connector for +12, A, B, 0v, leaving the other 2 pins (R- and R+)
empty. Connect the +12, A, B and t
he reader
shield wire
to 0v terminals on the
Reader Input
.
b.
A 4-wire RS-485 requires a 6-position connector for +12, T-, T+, 0v, R-, R+, where T- means Transmit Inverted signal, and R+
means Receive non-inverted signal.
2.
Any unused wires on the reader must be evenly snipped and have their tips insulated using electrical tape or
equivalent. The shield wire on the reader must also be completely insulated to prevent ground loops.
3.
If you have any
supervised input contacts
, wire them to the
Digital Contact Inputs
using Method 1 or Method 2.
4.
If you have any
non-supervised input contacts
, wire them to the
Digital Contact Inputs.
5.
If you have a
relay output contact
, wire it to the
Relay Output
.
6.
Supply power to the Freedom Bridge using either or both of the following methods:
a. Wire
12 - 16Vdc
power, up to
400mA
, directly to the terminal on the Freedom Bridge.
b. Connect a Cat5, 5e, or Cat6 cable from any non-PoE port on an Ethernet Switch to the RJ-45 port on the
Freedom Bridge.
Note:
Ethernet only supports a
maximum cable segment length
of
100m (328ft)
. Greater lengths can be achieved
by adding switches or repeaters every 100m (328ft).
7. To add the Freedom Bridge to a Freedom Server and configure it, refer to the Freedom Version 8 Software Guide.
A
flashing green “
Ready” LED light on the Freedom Bridge circuit board indicates that the bridge is attempting to connect to the server.
A
solid green “
Ready” LED light indicates that the Freedom Bridge has established a connection to the server and is ready to use.
