HCS365
TABLE 3-3:
3.1
The HCS365 contains two transmitter configurations
with separate serial numbers, encoder keys, discrimi-
nation values, counters, and seed values. This means
that the HCS365 can be used as two independent
encoders. The code word is calculated using one of two
possible encoder configurations. Most options for code
word and modulation formats can be different from
Encoder 1 and Encoder 2. However, LED and RF
transmitter options have to be the same. The SHIFT
input pin is used to select between the encoder config-
urations. A low on the SHIFT pin will select Encoder 1
and a high will select Encoder 2.
