The X1 terminal is connected to the intrinsically safe Raptor Tankbus.
A jumper on the X2 terminal enables the built-in termination. The termination
should be used if the Rosemount 5900 gauge is installed at the end of a
Tankbus network. See “The Raptor Tankbus” on page 3-41 for more
information on how to terminate the Raptor Tankbus.
The X3 terminal is used for connecting the cable shield in order to enable a
continuous shield throughout the Tankbus network.
The X4 terminal can be used for “daisy-chain” connection to other Raptor
devices such as the 2240 tank temperature multiplexer, or the 2230 tank
display unit, see also Figure 3-22 on page 3-47.
