Wiring Characteristics; Power Supply Wire; Lonworks  Data Cables - Honeywell Temaline TK-S014 Installation Manual

The connections shown are:
•
The Power supply connection: it connects the Power Supply device whit other Temaline devices
•
The LonWorks connection: to connect the TemaServer with the RTUs
•
The Input and Output are used to connect the physical door managed (lock, Door sense, REX and
others)
•
The Reader connections: are Wiegand lines that connect RTU-A08 with the third party readers.

LONWORKS Data Cables

The LONWORKS data cable must be twisted-pair.
In a free topology configuration, the total length of the sections must not exceed 500m.
In a bus configuration, the total length of the sections must not exceed 2700m.
In a free topology configuration, activate the 51 ohm terminator by placing the appropriate jumper on the
related TemaServer device:
•
For TS AC close the jumper on LonWorks plug-in.
•
For TS2 close JP1 on the LonWorks MIP board.
For further details please refer to the related TemaServers Installation guides.
In a bus configuration, place two terminators (with resistance values of 100ohm 1% ½W) at each end of the
bus.
