Optional Network Connection - Linear AE-2000 Installation Instructions Manual

Optional Network Connection

Linear's AE-1000, AE-2000, & AM-3 Access Control Systems can
be connected together in a network. A network will allow sharing
programming and user information between the systems.
Network wiring conforms to 3-wire RS-485 electrical specifi cations. Units
connected in the network can be wired using one unit as a "hub" or by
wiring from one unit to the next in "daisy-chain" fashion. See the fi gures
for wiring options.
• Use Belden 9925 or Carol C0600 shielded cable or equivalent.
Maximum wire run distance is 4000 feet.
✦ NOTE: Be sure to connect the cable's shield to one of the GND
terminals.
Network with Hub
1. Mount and install the units for the network.
2. Choose one unit to be the Network Hub. Usually this would be a
centrally located or "main" unit.
3. Route 3-conductor shielded cable from the hub unit to one of the
other units. Repeat this step to connect the hub unit to each of the
other units.
4. Connect the 3-conductor cable to each unit's NETWORK
terminals.
Network Daisy-chain
1. Mount and install the units for the network.
2. Route 3-conductor shielded cable from one unit to the next unit
until there is cabling run to all of the units.
3. Connect the 3-conductor cable to each unit's NETWORK
terminals.
