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 2-1 illustrates the layout of the MBE printed-circuit board.
Table 2-1 provides 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 2-1 and 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 2-3 for jumper locations).
