3.7.1 Wiring for Multiple AutoDomes
To wire multiple AutoDomes in a series, or “daisy chaining,” you must apply a terminating
resistor to the last dome of the series. The Interface Board is supplied with a 100 Ω
terminating resistor located between the Biphase terminals C- and C+ (pins 1 and 2) of the
P105 control connector (see item 5 in Figure 3.10 above). Remove the resistor from all but the
last AutoDome Interface Board. The maximum number of AutoDomes that can be daisy
chained is four (4).
If using the RS485 protocol for control, switch the terminating resistor from the Biphase C+
and C- terminals to the RxD+ and TxD- terminals (pins 4 and 5) of the P105 control connector
for the last dome (refer to item 6 in Figure 3.10 above).
