Keri System’s Keri Keys Receiver is a two-channel output receiver capable of outputting two separate channels based
upon which button is pushed on the clicker/transmitter. The receiver outputs data in a format compatible with Keri
Systems MS series readers as used with the PXL-500P Tiger Controllers and is capable of operating reliably at 300 feet
using the receiver’s built-in antenna. Greater distance can be achieved with use of an external antenna.
1.0 Keri Keys Receiver Configuration
The diagram below shows the configuration of the receiver board.
Figure 1: Clicker Receiver
1.1 Channel Select Configuration
By using two receivers you can use the four button clicker to operate up to four entrances. Setting the channel select
switch to 1/2 will allow it to operate with clicker buttons 1 and 2. Setting the channel select switch to 3/4 will allow use of
clicker buttons 3 and 4 (see Figure 1 for location of the channel select switch).
The chart below shows the function of each of the 4 clicker buttons.

3.0 Two Channel Operation Wiring
This receiver is designed to output data on two separate channels. This allows one receiver to control two entrances when
using the four button clicker.
NOTE: For Single Channel Operation, connect the Channel A output only.
3.1 One PXL-500P
Figure 2: MS-1400 Keri Keys Wiring - 1 PXL-500P
3.2 Two PXL-500Ps
NOTE: When connecting the receiver to two PXLs, connect the 12VDC from only one PXL-500P.

4.0 NXT-RIM Wiring
If an NXT-RIM is needed to connect the receiver to an NXT reader, use the following information. For information on
connecting the NXT-RIM to a reader see the NXT Reader Interface Module Installation Guide

Installation Guide
5.0 Housing
The receiver is housed in an IP67 rated enclosure, which is dust and moisture resistant. It can be mounted outdoors on
fences, buildings, etc.
NOTE: When installing the lid, care must be taken to insure the gasket fits properly in the correct slot. Failure to do this,
will allow water to enter the box.
Figure 6: Clicker Receiver Enclosure
6.0 Mounting
The receiver should be mounted in an area that is relatively free of large metal obstructions such as ductwork, appliances,
wire lath, etc. The enclosure can be attached to a wall, fence
unit.
The receiver comes mounted on the lid of the enclosure. This allows ample space for cabling, conduit entrance, etc. If
required, the receiver may be mounted to the base of the enclosure. To ins ert the 4 conductor cable into the enclosure, take
a small screwdriver, or other small sharp object and push it through the grommet opening. Continue pushing until it
pierces the interior of the grommet. Remove the screwdriver and insert the cable through the grommet.
NOTE: It is recommended to attach a tie wrap around the cable at the grommet and if more strain relief is needed mount
a “P” clamp to a nearby boss using a #4 self tapping screw.

, etc. with the 4 mounting holes provided on the base of the
7.0 Receiver Read Range
To insure the receiver is located in a good coverage area when first installing:
1. T ake a clicker to the furthest point where coverage is desired. Depress the appropriate button twice and have someone
watch the LEDs. Both the Red and Green LEDs will blink off momentarily if you are in range.
2. If the receiver range is greater than desired, proceed as above and have someone turn the Range Adjustment control
counter clockwise until the LEDs do not respond. Then turn clockwise by a degree or two. If the LEDs now respond,
the receiver range has been set to the location desired.
3. If the receiver is mounted in a metal housing, or in some other location that adversely affects the read range, an
external antenna will need to be mounted. To add an external antenna, open the grommet on the top of the enclosure
as previously done for the data cable.
4. The coaxial cable is passed through this and connected to the external antenna terminal at the top of the receiver
board. Make sure to connect the coax shield to the “GND” connector and the center conductor to the “ANT.”
5. Mount the antenna in a location that allows the desired read range.
1. A metal fence will require the use of an external antenna.
