* T966 charging racks connected to charging interface T966CI are powered via the
12-conductor cable. Charging racks not connected to the interface must be powered
separately.
Linear power supplies are generally recommended, specially for the transmitters
(7410, 5A) and at locations with strong electromagnetic fields.
System interface module T840IU is powered by the T840 central unit in which it is placed.
8 Addressing
All units connected to the system bus must have an address to enable communication
with other modules. The address must be set with the address switch before power is
applied to the unit, as the address is read and stored at start-up. At start-up the function
indicator (LED) on the unit starts to blink at about 8 Hz and after max 90 seconds lights
continually. This indicates that communication with the central unit has been established.
