Installation
The System Diagnostic Unit connects to the mobile system through a standard EC300/EC400
communication cable that is supplied with the unit. The cable has six or eight wires and is
terminated with a twelve position red connector on the end. (Newer diagnostic units that get their
power from the logic board require the 2-wire connector to plug into either J10 or J26 on the logic
board). Connection to the Power Pro requires a twelve to ten pin adapter and uses J12 or J13 for
power. The Diagnostic Unit must be connected to the left side of any module of Spacesaver
mobile storage. This means that the System Diagnostic Unit has the left end of system jumper on
its left communication connector, internally, with the supplied communication cable attached to its
right communication connector. This cable is then connected to the left communication connector
of the first Power Pro, EC300 or EC400 carriage control or safety floor monitor. This
communication connection is illustrated below.

-- Communication Connections for Diagnostic Unit --
The actual number and arrangement of units within any module of Spacesaver mobile storage will
vary from module to module. Keep in mind, however, that in most cases the System Diagnostic
Unit should be connected to the left communication connector of the first Power Pro, EC300 or
EC400 carriage control or safety floor monitor. This configuration works for both diagnostic and
remote control functions. However, to program a Power Pro, EC300A or EC400 connect to the
first carriage controller, bypassing any floor monitor, autocycler or T-Board. The diagnostic unit
may be plugged into the left communications connector of any logic board in a module. However,
the diagnostic will only address logic boards to the right of this connection point.
