7 F2-20GF1 I/F This device is obsolete and quite rare. There were at least two other Interface units, either of which would work in place of the F2-20GF1.They are F-LINK and A-LINK. As these are so rare, we will concentrate on the F2-20GF1 for this procedure.
8 Components Needed: 1) Programming Software: MELSEC MEDOC2) Interface (I/F) to connect to programming port on F / F1 / F23) Serial Protocol Converter – i.e. PCX-KIT1.
11 PCX-KIT1This kit from Mitsubishi Tech Support incorporates a connector (adapter) which:connects to the DB25 connector on top of the F2-20GF1,Converts the Serial Protocol from RS422 to RS232C,Provides Power (12VDC) to the Converter,And, Provides connection (DB9) to your computer.
12 PCX-KIT11) Remove the access cover on your Mitsubishi PLC.
13 Mount F2-20GF1The F2-20GF1 mounts on the port (also used for hand-held programmer). The two blue connectors fit together, and the two “sliders” on each side of the F2-20GF1 hold the I/F securely to the PLC.Note the end of the F2-20GF1 is flush with the end of the PLC (mentioned just as an aid to positioning).

20 Connection… 1 Install F2-20GF1 on PLC 2 Slide “tabs” to secure I/F on PLC3 Connect cable to I/F4 Plug 12VDC Transformer into 120VAC source.5 Insure that connections are secure on “electronics box” (the actual I/F).6 Connect I/F to your PC COM Port.
21 Complete the Connection ! Your installation should like something like this…
22 Connect the Power !Now is the right time to connect the 12VDC to the I/F…
23 F2-20GF1 in Action.Briefly, all the RED LEDs come on, then after the F2-20GF1 determines which unit to which it is connected, that LED comes on solid. In this case, the F1/F2 LED is lit.
24 Putting It All Together… You’ve got MEDOC Running on your PC…You’ve got the F2-20GF1 and the PCX-KIT1 connected from the PC to the PLC…And you’ve remembered to plug in the 12VDC …
25 Now the hard part begins! We at Lighthouse PLCs, Inc. hope you will benefit from this tutorial/primer.Communications with the older Mitsubishi (as well as other brand) PLCs is rapidly becoming a lost art.And, relevant manuals and documentation are becoming as rare as the PLCs themselves.
