Configure the ConnectPort TS serial ports

This section explains how to configure your ConnectPort TS device for basic serial port connectivity. For more detailed information, see Configure the device using the web interface.

Use the Digi Discovery Utility to find devices

You can use the Digi Discovery Utility to discover devices present on a network. You can select a device from the list, and then configure the serial ports.

See Use Digi Device Discovery utility to sign in to the web interface.

Configure serial ports

You can configure serial port settings using port profiles. Port profiles are a defined set of serial port parameters for a particular use. For information about which port profile to select, see Select Port Profile.

Note Digi recommends the RealPort port profile. If you want to manage your serial ports with Digi's RealPort software, download the RealPort software.

Configure EIA-232 devices to connect using 8-wire cables

For EIA-232 devices that will be connected using 8-wire cables, configure the Altpin setting. The default for this setting is off, and it must be enabled as needed for each serial port.

  1. Select the device in the Digi Discovery Utility.

  2. Click Advanced Serial Settings.

  3. Select the Enable alternate pinout (altpin) setting.

  4. Click Apply.

Configure serial ports that connect to EIA-422 or EIA-485 devices

The serial ports for ConnectPort TS 8/16 MEI products are set to EIA-232 by default. For serial ports that connect to EIA-422 or EIA-485 devices, configure the serial ports as follows.

  1. Click the serial port to select it.

  2. On the Serial Port Configuration page, click the Multiple Electrical Interface (MEI) Serial Settings link.

  3. Select EIA-422/EIA-485.

  4. Select the number of differential wires the device uses for communication:

    • 2 wires: A half-duplex connection with shared transmit and receive wires.

    • 4 wires: A full-duplex connection with independent transmit and receive pairs. This is the default setting.

  5. Select Enable termination if you require termination or use of biasing resistors across the lines. Enable this setting if the terminal server port is an endpoint node of the EIA-422/485 network and you want termination or biasing. 2-wire mode uses termination or biasing at one of the end points; usually the Master endpoint.

Note The CTS and RTS controls signals are available as separate differential signals in the EIA-422/EIA-485 4-wire mode. Do not use these differential signals in 2-wire mode. The CTS and RTS differential signals are not terminated or biased internally. If you require termination or biasing, it must be done externally.
