S600 Instruction Manual
to current using a bit link (jumper) on the board to place a high
accuracy calibrated shunt resistor in parallel with the input. Refer to
Figures 4-4 and 4-5.
Caution
Set the channels for each A/D converter to the same value to guarantee
accuracy. Set all channels ANIN 1-5 on the first A/D converter for either
voltage or current. Set all channels ANIN 6-10 on the second A/D
converter for either voltage or current. Refer to Table 4-13 for P144 I/O
Bit Link settings.

The ANIN channels use the connectors labeled SKT-A and SKT-B,
which are located on the backplate of the P144 board. Channels CH1
to CH10 are located on connector SKT-A. Channels CH11 and CH12
are located on connector SKT-B. Refer to Tables 4-1 and 4-2 for the
ANIN pin connectors.
