10.2 Encoder connections

Differential pair encoder.

(Output with complement)

Figure 4

Single ended encoder. (TTL or

CMOS)

Figure 5

Single ended event counter with

external count direction & index

control. (TTL or CMOS)

Note: If the counters are driven in a single ended mode as shown in Figure 4 and Figure 5,

then the unused phase inputs do not have to be biased at 2.5V. Each encoder input has two 100K

resistors that bias the input to 2.5V when no driving source is present.
