Introduction

The PCI-COM232 and PCI-COM232/2 provide 9-pin male “D” (DB9M) connectors that extend through
the backplate of the board. There are two options for the PCI-COM232/4. The C37F-4X9M-1M is a cable
that splits the ports into separate DB9M connectors, while the C37F-4X25M-1M splits the 37-pin
connector into four ports with DB25M connectors.
