Captive screw connector

The IPL T S2, IPL T S6, and IPL T SFI244 have COM ports with captive screw connectors. The two COM ports with captive screw connectors on the IPL T S2 are common to the two 9-pin D connectors. Only one connector can be used for each COM port. If you use a COM port captive screw connector, its 9-pin D port is not accessible.

The IPL T S6 has four COM ports with captive screw connectors that are independent of COM ports 1 and 2, which have 9-pin D connectors.

The female captive screw connectors accept 3-pole or 5-pole male captive screw connectors that are wired as shown in the diagram below.
