Nortech CRC200+ Quick Installation Manual

Scope
This guide provides the basic instructions for installing, configuring and adding cards to the
CRC200+ Controller. Refer to the User Guide for detailed information on using the CRC200+.
Fitting the CRC200+
Release the front cover from the main unit by pressing the retaining buttons at the base of the unit
while you lift off the cover from the bottom (hinging the cover at the top).
Carefully unplug the ribbon cable linking the cover to the main unit (avoid pulling or bending the
ribbon cable). Completely remove the front cover.
Fit the unit to the mounting surface using the 2 keyhole slots and 2 mounting holes in the back
plate. Use 4 appropriate screws or nuts/bolt (M4) according to the type of mounting surface.
After wiring the unit, support the cover with one hand and carefully re-insert the end of the ribbon
cable into its socket. Refit the cover by engaging the top of the cover with the top of the housing
and hinging in the bottom of the cover until the securing buttons are fully engaged in the housing.

Reader Voltage Settings
Each of the two reader
interfaces includes a power
supply output that can be
individually set to either 5V or
"supply voltage" to match the
requirements of the
connected reader. The
voltage for each reader is set
on a jumper to the left of the
corresponding terminal block.
To avoid damage to the
readers, you must set the
correct voltage for each
reader before applying power
to the CRC200+. For use
with 12V readers, the power
supply to the CRC200+ must
be 12VDC.
If you are in any doubt about
the output voltage to the
reader, apply power to the
CRC200+ without connecting
the readers and measure the
voltage across the reader
+ve and -ve connector pins.
