Microtronix Access  Serial-TCP/IP Converter

4.3  Async Cables – Serial USB ports

When a USB serial adapter is connected, the connector has a standard DB9M RS232 DTE pin 
configuration.

4.3.1  Connecting to a DTE device

Standard null modem cables are used when connecting to a serial DTE device (like a PC COM port) 
that has a DB25 or DB9 male connector.

Null modem cable part numbers

DB9M­DB25M  ­  Serial port to DB25M
DB9MM    ­ Serial port to DB9M

4.3.2  Connecting to a DCE device

Standard straight through cables are used when connecting to a serial DCE device (like a modem) that 
has a DB25 or DB9 female connector.  If replacing a modem, avoid any modem handshake issues by 
configuring the device's interface for “leased line” or “permanent modem” type connection.
