2.5.4. Changing Terminator Switch Settings
The terminator switch is shipped from the factory in the “OUT” position (no termination). This is the correct
setting if the MZ is to be installed in the middle of a network. If the MZ monitor is connected as a single
device or if it is the last device on the network chain, the terminator must be moved to the “IN” position.
Locate switch #4 and determine its position. If it must be moved, slide the switch to the appropriate position.
(Note that switches 1-3 are for service use.)
