Edgeport/1i

Edgeport® USB-to-Serial Converters from Digi International provide high-speed serial connectivity via

USB port expansion for Windows-based applications. Edgeport/1i provides one RS-422/485 serial DB-9

port. For more detailed information, as well as the latest manual and technical updates, visit

www.digi.com/support/Edgeport.

Cabling Edgeport

USB connection

Type A

Type B

Plug the Type A (flat) end of the USB cable into the USB port located in the back of your PC or into an

available USB port on a standard hub or into a Digi International Hubport. Plug the Type B (square)

end of the USB cable into the Edgeport.

RS-422/485 serial connection

The Edgeport/1i supports RS-422/RS-485 protocol. To configure the features of RS-422/485

communication on the Edgeport/1i, you will short or leave certain pins unconnected at the DB9

connector of the cable. See the following pin assignment tables:

Jumper wire based mode configuration

For "jumper wire" based mode configuration, use the following pins:

Pin Description

1 ▶ full and half duplex

6 ▶ echo on and off

9 ▶ line termination

The user can switch on and off the following features:

n Line termination (120 ohm): To enable the line termination resistor, connect pin 9 to pin 8. To

disable line termination, leave pin 9 unconnected.

n Full Duplex and Half Duplex: For Full Duplex operation, leave pin 1 unconnected. For Half

Duplex operation, short pin 1 to pin 5 (GND) at the cable connector.

n Echo On and Echo Off: For Echo On mode, leave pin 6 unconnected. For Echo Off mode, short

pin 6 to pin 5 (GND) at the cable connector.

If the drivers are not already installed, see Edgeport driver installation.

Edgeport/2i

Edgeport USB-to-Serial Converters from Digi International provide high-speed serial connectivity via

USB port expansion for Windows-based applications. Edgeport/2i provides a combination of up to two

RS-422 and/or RS-485 serial DB-9 ports. For more detailed information, as well as the latest manual

and technical updates, visit www.digi.com/support/Edgeport.

Configuring the DIP switches

Two-position switch

The two-position DIP switch, located on the back panel, connects the signal ground to chassis ground.

IMPORTANT: Do not connect signal ground to chassis ground on more than one location in order to

prevent ground loops and potentially high currents.

Eight-position switch

The Edgeport/2i also has two sets of eight position DIP switches, located on the back panel next to

their corresponding serial port.

The following figure shows what each switch selects in the ON and OFF positions.
