5. Turn ON the Loopback Test Switch. To end the test, turn OFF the switch.
The Loopback Test Switches are as follows:
Board: CIO 1900, bit 06 for port 1 and bit 14 for port 2
Unit: n, bit 06 for port 1 and bit 14 for port 2 (n = CIO 1500 + 25 x
Unit No.)
Refer to 10-3 CIO Area Allocations .
6. Use the protocol status to check the results.
Refer to 10-3 CIO Area Allocations .
When the test is being executed, the indicators shown below will flash. Use
the protocol status to check whether or not the test has been executed nor-
mally.
Port 1: COMM1 indicator
Port 2: COMM2 indicator
Port 1: SD1/RD1 indicator
Port 2: SD2/RD2 indicator
This section describes the Setup Area allocated to the Serial Communications
Board and Serial Communications Units in the DM Area when loopback tests
are performed.
The loopback test is performed using the Host Link mode protocol. The Setup
is basically the same as for the Host Link mode.
