Quick Start Guide
• Consider mounting requirements - central versus distributed.
-
Central mounting places all controllers in one location, running lengths of cables out to each
door to support readers, inputs and outputs.
- Distributed mounting places each controller near the door it supports running short lengths
of cable out to each door, but running a long network communication cable.
• Note the locations of the knockouts in the enclosures and remove the appropriate knockout for
the easiest cable routing into the controller.
• Route all controllers in a network in a single, continuous daisy-chain.
• Route cables in accessible areas for ease of maintenance.
• Connect all controllers to a quality earth ground.
• Add transient suppression across electric devices attached to a controller output.
• Verify the controller's supply voltage is 12 VDC – long power line runs cause a drop in voltage
at the end of the run.
• Verify proper operation of the host computer's COM port.
• Attach the reader to be used for card enrollment to the master controller (this reader can be used
for access control as well as enrollment, but during the enrollment process the door associated
with the enrollment reader will not allow access until the enrollment process is complete).
4.2 Do Not
• Make modem phone line connections through PBX telephone switching systems - most
modems are not compatible with PBX systems leading to disconnection problems with the
modem.
• Locate a LC-200P controller near EMI sources - EMI sources can affect the performance of the
controller.
• Locate a reader near EMI sources - EMI sources can affect the performance of the reader.
• Use switching power supplies - they are EMI sources.
• Route network and reader cables beside power cables - transients on the power cables may be
picked-up by network and reader cables.
• Stretch or over-tension cables.
• Route cables over sharp objects.
• Let the cables get tangled.
• Mix LC-200Ps with PXL-100s in the same network.
• Connect earth ground to the network cable shield - the LC-200P automatically connects earth
ground to the shield at one point on the network to prevent ground loops.
• Use gender changer plugs when making RS-232 serial communication connections (unless you
know it is a "straight-through" plug) - gender changers may have internal wiring changes that
can disrupt communications.
