The DSE-410D has two DB-9 male connectors.

DSE-410D Port 1 - Multi-Interface, dip-switch selectable RS-232, RS-422, or RS-485

DSE-410D Port 2 - RS-232 only

RS-232 Connections

In the RS-232 mode, the ports are configured as DTE (Data Terminal Equipment), like a computer.

DTE Device (Computer or DSE-410D)

When connecting to a PC or another DTE device, use a null modem crossover cable. When connecting to a DCE device that can normally be plugged into a PC, use a straight through cable. Set Flow Control to None for 3-wire RS-232.
