DIO#.TERM

Description

Sets whether the bi-directional I/O is terminated or not.

Value	Description
0	Not terminated
1	Terminated
2	Override feedback auto-termination to not terminated
3	Override feedback auto-termination to be terminated

The following table shows what type of termination each bi-directional line supports.

DIO#	Valid DIO#.TERM Values	Description
DIO1 to DIO4	0 to 3	Controls 112Ω termination. DIO1-4 are auto-terminated for certain feedback types. If there is already an external termination resistor present, analog feedback faults may be present due to voltage levels being out of range. The external resistor should either be removed or auto-termination can be overridden with this command.
DIO5		DIO5 is not terminated by default. On newer AKD2G models, DC 136Ω termination is also available.
DIO6		DIO6 is not terminated. Internal termination is not available.

Examples

Using DIO# with a differential point-to-point connection:

If the AKD2G is the transmitter DIO#.TERM should be set to 0.

If the AKD2G is the receiver DIO#.TERM should be set to 1.

Using DIO# with differential multi-drop connection:

If the AKD2G is the transmitter DIO#.TERM should be set to 0.

If the AKD2G is the receiver the DIO#.TERM should be set to 1 on the last drive. The other receivers should have DIO#.TERM set to 0.

Connecting a single-ended, open-collector device to a DIO input.

The DIO#.TERM should be set to 0. The negative pin should be left disconnected / floating. Internal resistors in the drive will pull this to an appropriate level. The open-collector device should be connected between the positive pin and GND_I/O. The diagram below shows the bias resistors that are inside the drive.
