The ESP902 has two DB-9 male connectors.

ESP Port 1 - Multi-interface, dip-switch selectable RS-232, RS-422 or

RS-485.

ESP 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. ESP902 to device connections are the same.

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.

Refer to Appendix B for DB9 to DB25 Conversion Cables.
