Power Connector

Plug the ultra-miniature phone plug from the included power supply into the power jack and then plug the supply in. When power is applied the Red power light will illuminate. The tip of the power plug is positive; the sleeve is negative.

Reset Button

This switch resets the unit, similar to the effect of removing/applying power. The Reset switch is recessed to avoid accidental operation. To reset the unit, insert a small plastic tool, press lightly and hold for 3 seconds. The Link and Ready lights will go out and then come back on.

Serial Port Operational Modes

Using the ESP Manager or the Console Mode Configuration Menu each serial port can independently be configured as RS-232 Mode, RS422 Mode or RS-485 Mode. Port 1 of the ESP904 also can be placed in Console Mode, Upgrade Mode or Default Mode. Port 1 default setting is Console Mode.

Default Mode

When Default Mode is selected and the Server Properties are Updated (Saved) all the configuration settings return to their default values. The default settings for the ESP904 serial ports are: Console Mode for Port 1; RS-232 mode for Ports 2, 3 and 4.

Note:

Refer to Chapter 5 for details on Server Configuration settings

Console Mode

In Console Mode the ESP904 Configuration Menu can be accessed from a computer by connecting its RS-232 serial port to the ESP904’s Port 1. Since the computer is a DTE device, and the ESP904 serial ports are configured as DTEs (with DB-9M connectors), a null modem crossover cable must be used.

In Console Mode the default serial port settings are: 9600 baud, 8 data bits, No parity, and 1 stop bit. From Windows, HyperTerminal with VT100 terminal emulation can be used for Console Mode configuration.

Note:

Refer to Chapter 9 for details on Console Mode

Upgrade Mode

Using a similar connection setup to that used in Console Mode, firmware for the ESP904 can be updated by connecting the ESP904 to a computer via Port 1, using RS-232. (Upgrading also can be done by communicating with the ESP904 over the network connection, using the ESP Manager software and a virtual COM port mapped to the ESP904 Port 1.)
