7.5 Cable Specifications
This chapter deals with cable specification for AutroSafe (version 4
and earlier versions), Autroprime 2.0 and AutroMaster ISEMS.
Twisted pair cable is of type Category 5 or better with RJ-45
connectors. This cable is also called a “patch cable”.
The cable exists in two versions, either one-to-one cable or crossed
cable.
Crossed cable must be used for direct communication between
AutroMaster and AutroSafe/Autroprime.
One-to-one cable must be used if AutroMaster is connected to one or
several AutroSafe systems through a switch.
The length of one twisted pair cable must not exceed 90 meters.
If the communication distance exceeds 90 meters an amplifier or a
switch must be installed. The maximum distance when using a switch
is 180 meters. (Each twisted pair cable is 90 meters).
