Cabling may seem to be a trivial aspect to the installation, requiring nothing more

than planning the cabling route and pulling the cable through the building.  This is

true for Wiegand and power wiring considerations, however, if your installation

requires the use of RS-485 or Ethernet communications, then the choice of cable,

the cable run length, the network topology, and termination of the network may

be very important aspects that must not be overlooked.

*RS-232 communications distances are dependent on baud rate (bps).  For

example, at 9600 baud, a distance of 100 ft. is possible with shielded cable, but at

56 k-baud (kbps) a maximum of 20 ft. is recommended.
