5.2 Precautions for cable connection (A9GT-QJ71BR13)

(1) Restrictions on the cable length between stations
(a) When connecting between the network modules, the cable
lengths indicated in the table below should be used according to
the number of stations connected.
A communication error may occur if a cable length other than the
lengths indicated in the table is used.
Station-to-station cable length
0 to 1 m (3.28 ft.)
1 (3.28 ft.) to 5 m (16.4 ft.)
5 (16.4 ft.) to 13 m (42.65 ft.)
13 (42.65 ft.) to 17 m (55.78 ft.)
17 (55.78 ft.) to 25 m (175.63 ft.)
25 (175.63 ft.) to 300 m (98.43 ft.)
300 (98.43 ft.) to 500 m (1640.5 ft.)
(b) If there is the possibility of an increase in the number of stations
due to system expansion, install the cables with advance
consideration of the restrictions.
(c) When using a repeater module (models A6BR10 or A6BR10-
DC), use the station-to-station cable length indicated by "10 to
33" stations, regardless of the number of stations connected or
the number of repeater modules.
