15 • Data Cal 2000 Hardware Setup
Termination Switch
The termination switch is located above the left DB-15 connector on the
back of the docking module. It is a two position slide switch. The switch
position indicates whether the module is physically the last module in the
installation or not. When the Data Cal 2000 is viewed from the front, the
last module in the installation is the module on the far right and it must
have the termination switch set to the down position for the Data Cal
2000 to operate properly. All other modules in the system must have the
switch set to the up position. If only one module is used in a system, that
module must have the termination switch set to the down position.
Mechanical Assembly
The Data Cal 2000 is designed for table top use. Perform the following
steps to assemble the docking station and docking modules.
1. Find a location that is well ventilated and near a window so that the
exhaust can be routed out of the window.
2. Find a table or other flat surface that is large enough to
accommodate the docking station and the number of modules in
your system.
Set switch to UP position if module IS NOT the last one.
Set switch to DOWN position if module IS the last one.
