DIO#.TERM

Description

Sets whether the bi-directional IO is terminated or not.

Value Description
0 Not terminated
1 Terminated

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

DIO# Valid DIO#.TERM Values Description
DIO1 to DIO4 0 or 1 Controls 120Ω termination
DIO5 and DIO6   DIO5 and DIO6 is always AC terminated

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.
