INTRODUCTION 

The PathWay® Model 7183  Dual  Channel  BJ80 BNC  A/B/OFFLINE 
Switch with Secure Ethernet Remote  allows the user the capability of 
sharing a single port interface device,  connected to the “COMMON” 
port,  among two other devices,  connected to the “A” and “B” ports  for 
each channel.   Remote Control access can be accomplished using a 
Secure  Ethernet  10/100BASE-T connection  SSH  Commands.  The 
Model  7183  is  enclosed in a 1U, full rack size, all metal  black  chassis 
designed to provide EMI/RFI shielding and fit in a standard 19” rack. 

Features: 

 

The switch ports are transparent to all data. 

 

Both the center pin and the shell signals are switched via break-
before-make electromechanical relays.. 

 

Switch maintains last set position on power loss and continues 
to pass data. 

 

Switch powers up in last known position. 

 

Simultaneous Channel Control. 

 

Exclusive Ethernet Remote Control. No front panel control. 

 

Control of the switch position from a 10/100Base-T LAN 
Ethernet environment. 

 

Remote Control SSH Command Interface that allows the user 
to control switch position, lockout front panel operations, and 
obtain switch status. 

 

Remote allows query of switch position before selecting a new 
switch position. 

 

Front panel LED’s display present position and power status. 

 

All BJ80 BNC ports are impedance matched to support 50 Ohm 
equipment.
