Physical Dimensions and Cable Construction

This adapter measures 200 mm in length and 45 mm in width. Its height reaches 20 mm at the connector housing. The unit weighs 120 grams, adding minimal bulk to your programming kit. A fixed pigtail cable connects the two D-sub connectors permanently.

Internal Circuitry and Energy Storage

Twenty-four discrete components populate the small internal PCB. A 220 µF capacitor filters noise from the PC serial port. This capacitor also maintains signal levels during brief voltage drops. Consequently, the adapter provides reliable communication even with older laptop ports. A line driver IC converts voltage levels between RS-232 and the CPU’s logic interface.

Connector Configuration and Compatibility

A 9-pin female D-sub plugs directly into your computer’s serial port. A 15-pin male D-sub connects to the VersaMax CPU programming port. You do not need any additional adapters or gender changers for this link. The adapter works with IC200CPU001, IC200CPU002, and later VersaMax models. Therefore, this single cable supports your entire VersaMax fleet.

Programming Use and Baud Rate Support

You can upload ladder logic, download configuration changes, and monitor live data. The adapter supports baud rates from 9600 to 115200 automatically. Simply select the matching speed in your Proficy Machine Edition software. LED indicators are not present on this passive adapter design. Always disconnect the cable before powering down the PLC system.
