4-2 Wrap Communications Test
This section explains the wrap communications test for the two communications
ports of the Host Link Unit.
Execute the wrap communications test as follows:
1, 2, 3... 1. Set the unit number to an appropriate number within a range of 0 to 15.
2. Set the node number to an appropriate number within a range of 0 to 31.
3. Set the DIP switch as shown in the following tables:
