PREFACE
■Objectives and intended readership
The MB2142-03 support tool (parallel communications adapter) is designed to enable the
development and evaluation of products based on the F2MC* family.
The MB2142-03 is connected to the main unit (MB2141).
This enables the main unit to perform parallel communication with the host machine (such as a
personal computer).
This manual describes the handling and connection of the MB2142-03. It is aimed at engineers
responsible for the development of products based on the F2MC, using the MB2142-03.

2.2 Connection to Main Unit
As shown in Figure 2.2, use an IF cable to connect the parallel communications
adapter to the main unit (sold separately).
■Connection to main unit
As shown in Figure 2.2, use an IF cable to connect the parallel communications adapter to the
main unit (sold separately).
For details of connecting the IF cable to the main unit, refer to the 2140 Main Unit MB2141
Emulator User’s Manual.
■Notes
When connecting the parallel communications adapter to the main unit (sold separately), keep
the following points in mind:
❍Turn off the power before connecting or removing a cable. Attempting to connect or
remove a cable while the power is turned on may cause a malfunction.
❍To remove a cable, do not pull the cable itself; grasp and pull the connector. Pulling the
cable itself may cause a conductor inside the cable to break.
