Drawing 3-15 Typical Point ID

configurations.

The cables in Table 3-7 have been listed by preference. When using shielded cables, the

shield should be left unconnected, as this causes an increase of bus wiring capacity.

Table 3-7 Tested cable types.

Product Description Diameter mm

WCAT54 FTP cat.5, 4 twisted pairs 0,22

WN108 Unshielded, 8 non-twisted wires 0,22

WS108 Shielded, 8 non-twisted wires 0,22

The two tables– Table 3-8 and Table 3-9 – contain the test result for different numbers of

connected devices under different power demand conditions of the two and four wire

system bus. The load is given in UL (1 Unit Load = 300 uA) – a typical load of one

transmitter/receiver device of the Point ID

bus. All the available wires in the cable have

been used for connections. The presented data clearly shows that the bus range

depends mostly on the load of the connected devices.

The minimum bus voltage is 9,5VDC.

When using cables with less wire cores (less wire gauge), the range should be

appropriately reduced. Example: WN104 – 4 wires, 0.22mm

– the range is reduced by

50%. In case of twisted pair cables, the pair separation between PID+ and PID- should

be avoided.
