2.6 Connectors Pin Assignments
The ACL-8111 has three connectors: one 37-pin D-type connector
(CN1) and two 20-pin insulation displacement connectors (CN2 and
CN3).
CN1 is for analog input and analog output signals. CN2 is for digital
input signal. CN3 is for digital output signal. The pin assignments
for each connector are illustrated in the Figure 3.1 ~ Figure 3.3.
