3 Interfaces Reference

Pinout Information

Console Connector

The console connector on the P840 is a DCE interface on a RJ45 pinout. The supplied DB9 to RJ45 converter

should be used to connect to the DB9 connector of a DTE terminal. This connection will then provide access to the

built-in menu system.

If the console interface is to be connected to a modem or other DCE device, a standard RS-232 crossover converter

should be used.

The following table illustrates the console pinouts.
