Configuring MBE

This section describes how to configure MBE for a typical application.

Bridge Application

Typically, MBE is used in a bridge application. In bridge mode, MBE units operate in pairs, with one MBE unit located at the main Ethernet LAN, and a second MBE unit located at the remote LAN. Each MBE unit is configured differently depending on its location and the application. Configuration is performed through hardware switches and menu-driven software. See the LAN RANger Series Configuration Guide for software configuration instructions.

Figure 2-1illustrates the layout of the MBE printed-circuit board.

Table 2-1provides details on the functions of the internal jumpers and switches, and their default settings.

To configure the MBE unit:

1.Disconnect the MBE power cord. It is not sufficient to turn off the POWER switch on the rear panel.

2.Unscrew the cover screw located at the rear of the unit and keep it in a safe place.

3.Remove the MBE cover.

4.Determine the required configuration of the MBE unit and set the internal jumpers and switches accordingly (see Table 2-1).

5.Configure the MBE LOCATION (SW1):

REMOTE – MBE is located on the remote LAN

MAIN – MBE is located on the main LAN.

6.Set the Chassis GND Jumper Setting (JP7) between the signal ground and the chassis (protective) ground (see Figure 2-1and Table 2-1):

ON – connect

NC – disconnect

7. With the 4-wire option:

Use the rotary switch on the 4W link interface card (see Figure 2-2)to select a data rate. The data rate may also be selected via the software (see the LAN RANger Series Configuration Guide for software configuration instructions). The data rates for maximum required range are listed in Table 2-2.

8.In bench testing, where one MBE is configured as DTE and the other as DCE configure the MBE link interface:

DCE

DTE – for normal operation (see Figure 2-3for jumper locations).
