Distances between receivers and Bus power supply unit
With 1 receiver 20581, 19581, 14581 powered by Bus 300 m
With 2 receivers 20581, 19581, 14581 powered by Bus 150 m
With 3 receivers 20581, 19581, 14581 powered by Bus 100 m
With 4 receivers 20581, 19581, 14581 powered by Bus 75 m
Important
If the receivers (20581, 19581 or 14581) are powered directly by the Bus and not from the auxiliary power supply
unit (20580, 19580 or 14580), the distance from the system power supply unit (01801, 01400 and 01401) is
reduced:
Wiring development Condition 1 Condition 2
If AB < 300 m:
• no limit on position between RX and TX
If AB > 300 m:
• ensure that the maximum distance
between TX and RX is less than
300 m (see diagram G, H and I)
If Max (AB,AC,BC) < 200 m:
• no limit on position between RX and TX
If Max (AB,AC,BC) > 200 m:
• ensure that the maximum distance
between TX and RX is less than
300 m if there is no crossing of the
shunt or it is less than 200 m if the
shunt is crossed
If Max (CD,AB) < 200 m and Max (AD, BD, AC,
BC) < 100 m:
• no limit on position between RX and TX
If Max (CD,AB) > 200 m and Max
(AD, BD, AC, BC) > 100 m:
• ensure that the maximum distance
between TX and RX is less than
300 m if there is no crossing of the
shunt or it is less than 200 m if the
shunt is crossed or less than 100 m
if there are two shunt crossings
