Making Hardware Connections

Default Mode

When Default Mode is selected and the server properties are Updated (Saved) all the configuration settings return to their default values.

Note:

Refer to Chapter 5 for details on Serial Server Configuration settings.

See Chapter 12 for Serial Server default parameters.

Console Mode

In Console Mode the Configuration Menu can be accessed from a PC by connecting its RS-232 serial port to the ESP901 serial port or ESP902 Serial Port 1. Since the computer is a DTE device, and the 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

configuration.

Note:

Refer to Chapter 9 for details on Console Mode

Upgrade Mode

In Upgrade Mode firmware can be uploaded from a PC via its serial port to the ESP901 serial port or ESP902 Serial Port 1. Upgrading also can be accomplished via the network connection, using the ESP Manager software and a virtual COM port.

Note:

Refer to Chapter 8 for details on Upgrade Mode

RS-232 Mode

In RS-232 Mode the currently selected serial port is configured as an RS-232 interface supporting eight RS-232 signal lines plus Signal Ground and is configured as a DTE, like a computer. Signals are single ended and referenced to Ground. To use handshaking, Flow Control must be set to RTS/CTS during Configuration.

Note:

Refer to Appendix A for RS-232 connection pin-outs.

Making Hardware Connections

RS-422 Mode

In RS-422 Mode the currently selected serial port is configured as an RS-422 interface supporting four RS-422 signal channels with full duplex operation for Receive, Transmit, RTS (Request To Send) and CTS (Clear To Send). The data lines are differential pairs (A & B) in which the B line is positive relative to the A line in the idle (mark) state. Ground provides a common mode reference. To use handshaking, Flow Control must be set to RTS/CTS during configuration.

Note:

Refer to Appendix B RS-422 connection pin-outs.

RS-485 Mode

In RS-485 Mode the currently selected port is configured as an RS-485 interface supporting transmit (TX) and receive (RX) signal channels using 2-wire, half-duplex operation. The data lines are differential with the Data B line positive relative to Data A in the idle (mark) state. Ground provides a common mode reference.

Note:

Refer to Appendix C for RS-485 connection pin-outs.

RS-485 Receiver Biasing

RS-485 Receiver Biasing can be implemented from the Serial Server if the network does not supply it. Remove the two side-cover screws of the Serial Server, slide the cover off and re-position the bias jumpers (shown open in the figure below) to enable biasing (shorting).
