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.
|
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.
