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.
