a. The DT9857-08 and DT9857E-08 support eight analog input channels (channels 0 to 7), the tachometer input
(channel 8), general-purpose counter 0 (channel 9), measure counter 1 (channel 10), measure counter 2
(channel 11), and the digital input port (channel 12). The DT9857-16 and DT9857E-16 support 16 analog
input channels (channels 0 to 15), the tachometer input (channel 16), general-purpose counter 0 (channel
17), measure counter 1 (channel 18), measure counter 2 (channel 19), and the digital input port (channel 20).
