antenna coil (Pins 1 & 2), plus a SEPARATE 4-conductor shielded cable to the
LED and Beeper (Pins 3 - 6). These cables can be run in the same conduit.
Connect the cable shield from the LED/Beeper cable to the black wire (GND)
on P1 at the RK600.
Route the auxiliary reader cable at least two feet away from sources of EMI
(electro-magnetic interference), such as radio transmitters, elevators, large
electric motors or fluorescent light ballasts.
Use of any Auxiliary Reader cable which combines all
conductors inside one shield and/or uses twisted pair for
the antenna lines will result in severely reduced reading
distance. Failure to properly ground the cable shield for
the LED/Beeper lines will also result in severely reduced
reading distance.
NOTE: When power is applied to the RK600, the unit is
calibrated for the current antenna configuration. Always
connect the Auxiliary Reader first, before applying power
to the RK600.
Surface-Mounted Wiring
For installations where it is necessary to run cable along the wall surface
(such as in a wall-mounted modular raceway) small break-away knockouts
are provided on the bottom of the RK600 and Auxiliary Reader housings,
as well as on the Spacer. Remove the knockouts with small pliers, and butt
the raceway up against the opening in the housing to conceal the cable.

Power

The RK600 can be powered by the optional RK-PS 12VDC power supply,
which is rated for powering the RK600 only. Alternatively, use any good 9-14
VDC supply which provides at least 150mA. DC power should be clean and
filtered with no more than 1 VAC ripple (Peak to Peak). Do not run AC power
in the same cable with DC power to the reader.
600
RK600 will not operate on AC Voltage or
with DC polarity reversed.
