Prior to an actual data transaction between the Host Link Unit and host comput-
er, check the system by following the nine steps listed below.

The following program example is designed to send test data to the Host Link
Unit and return it, unaltered, to the host computer. By executing this program, the
transmit and receive data are both displayed on the screen of the host computer.
If the transmit data and the receive data match, the system is operational. The
example uses a multiple-link system, and the program is executed by Host Link
Unit number 0. The following program is for NEC computers. For IBM compa-
tibles, four lines must be changed as shown after the program.
Check the settings of the Host Link Unit’s DIP switches and selectors. make
sure the transmission speeds, specified interfaces, and data formats of
both the Host Link Unit and host computer match.
Mount the Host Link Unit to the PC.
Connect the Host Link Unit to the host computer with the proper cable. For
details, refer to Sections 1 Introduction and 2 Host Link Unit Characteris-
tics.
Apply power to the PC and the host computer.
If the ERROR or ALARM indicators on the PC illuminate, rectify the error
and then clear the alarm.
If the Host Link Unit is ready, the RUN indicator will illuminate. Confirm that
this is ready before proceeding.
Prepare and execute a test program on the host computer.
If the data test is completed successfully, the system is operational.
If an error occurs, perform the required error processing as detailed in Sec-
tion 5 Error Processing.
