3-7-2 Connections to Optical Module
The connection method of the optical interface varies with the communications
port.
It is possible to connect an Optical Module directly to communications port 1. By
turning on the 5-V power supply switch of the Host Link Unit, 5 V is supplied to pin
14 of the communications port 1 so that no AC Adapter is required for the com-
munications port 1.

It is impossible to connect an Optical Module to the 9-pin connector of the Host
Link Unit directly. You must prepare a conversion cable to connect the Optical
Module to the 9-pin connector. AC Adapters are required for the Optical Modules
at the Unit and at the host computer. The following diagram shows the connec-
tions of the Host Link Unit to the host computer via communications port 2.
