Parts of the Board and Explanation

CN1

: Connector for connecting to an A/D converter board.

A PCB37PS series cable can be used if connecting to an

analog E series board.

CN2

: Connector for connecting another ATII-8C in cascade.

TB1

: Terminal for connecting external power supply (+5V -

+9VDC). If JP2 is set to external power supply, connect

the external power supply to this terminal.

TB2

: Terminal for analog output signal. Use to connect the

analog output signal (OUT0) on analog E series boards to

an external device.

CH0 - CH7 : Terminals for analog input signals.

Use to connect external devices or thermocouples.

JP1

: Jumper for selecting the signals connected to CN1.

JP2

: Jumper for the power supply setting.

JP2 specifies the power supply for this product.

Supply +5VDC from the A/D converter board via CN1.

This is only available when using the analog E series.

Set JP2 to 1 - 2.

Supply +5V - +9VDC from an external power supply.

Set JP2 to 2 - 3 when using an external power supply.

JP3 - JP26 : Jumpers for voltage or current input selection, input gain

selection, and CJC selection
