Figure 3-1: Connections to open-collector control signal (common-anode)
Encoder Connections
If the encoder drains less than 50mA, the DCS303 can supply the encoder directly,
and connect it as Figure 3-2. If the encoder drains more than 50mA, use an external
DC supply and connect it as Figure 3-3. Note that twisted-pair shielded cabling
provides the best immunity in electrically noisy environments.
