Keri Systems PXL-250 Quick Reference

PXL-250 Quick Reference

This Quick Reference is designed for the experienced installer as a quick reference while installing to
ensure all connections are made properly.

The Quick Reference is designed as a checklist of sorts where you may check off as each installation
procedure is completed. Additional information is given for those who need to be reminded of what
is performed during that part of the installation. For detailed information on installing the PXL-250
Tiger Controller, see the PXL-250 Quick Start Guide
Technical Reference Manual (P/N 01836-004).

If this is a PXL-250W Wiegand controller, verify the JP4 Wiegand reader voltage supply jumper

is set correctly. The default position for the JP4 jumper is set at 5 VDC (jumper across pins 2-

3). If your Wiegand compatible reader requires 12 VDC, move the jumper on JP4 from pins 2­3 to pins 1-2 while the power is off. When 12 VDC power is being supplied to the reader, the
POWER READER warning LED (located above the JP4 jumper) turns red. If 12 VDC is

applied to a 5 VDC reader, the reader may be damaged. Keri Systems, Inc. cannot be held
responsible for a reader damaged in this way.

NOTE: Early revisions of the surface mount PXL-250W mislabeled the JP4 jumper as JP5. All
instructions for the JP4 jumper apply to the jumper labeled as JP5 (see Figure 1 for the location of
the jumper).

1.0 PXL-250: Before Turning Power ON



Verify 12 VDC is supplied to the controller.

1.Verify the power supply is the correct voltage by first setting the tester to AC and checking
the voltage the power supply. If it reads over 1 volt AC, then you will need to use a different
power supply (preferably linear).

2.Set the DVM to a DC volt scale capable of reading 12 VDC.

3.Turn the power supply ON.

4.Place the Red DVM lead on the power supply’s terminal block output - Pin 1. Place the
Black DVM lead on the power supply’s terminal block output - Pin 2. Check the DVM read­ing. It should read between +12 VDC to +14 VDC.

5.If the DVM does not read between +12 VDC to +14 VDC, verify the power supply is of the
correct voltage (see step 1 above), verify the cable length does not exceed 200 feet, and ver­ify the cable gauge is AWG 18. This problem must be corrected before power can be sup­plied to the controller.

6.Turn the power supply OFF.

7.Connect the power supply’s terminal block output to the TB-2 connector on the PXL-250
controller.

8.The controller is now ready to be powered ON.

NOTE: On long power cable runs, keep in mind the resistance in the cable itself causes a drop in
voltage at the end of the run. The power supply must be able to account for this voltage drop.



Verify all wiring connections are secure and are made to the correct Terminal Block pins.



Verify a good earth ground has been connected to TB-2, pin 3.



If the controller is not using a door contact switch, verify a door switch input jumper is

connected between TB-4, pins 1 and 2.



Verify transient suppression has been installed on all electrical devices connected to a

controller’s outputs.

2.0 Powering the controller for the first time:



Reset the controller’s RAM.

1.Turn the controller’s power off.

2.On the controller, insert a jumper across pins 1 and 2 of JP3.

3.Hold the S1 Address and Diagnostics Button down and turn the controller's power on. The
beeper for the reader attached to the controller will beep as power comes on followed by a
beep-beep indicating the controller's firmware has reset the controller's RAM.

4.Release S1. If the optional Alpha/Numeric Display has been installed, it will display a "SYS­TEM RESET" message. Turn system power off and remove the jumper on JP3. The control­ler is ready.



Set the controller’s address.

1.Turn the controller's power off. Verify JP3 is not installed (if JP3 is installed, the controller
RAM will be reset when the power is turned on).

2.Hold the S1 Address and Diagnostics Button down and turn the controller's power on. The
beeper for the reader attached to the controller will beep as power comes on followed by a
beep-beep indicating the controller's firmware has entered the address setting mode.

3.Release S1. The address display LEDs then become active and the controller's address can be
set. If an Alpha/Numeric Display is connected to the controller, "ADDRESS CHANGE" will
appear on the display. The address range is from 1 to 128 (the Master Controller must be set
to address 1).

4.Quickly double clicking S1 toggles between increasing and decreasing the controller
address. The top LED character will display either a "+" or a "-" to show which direction is
active. A single click of S1 changes the controller address by 1. If you're at address 128, a +1
click will roll the address over to 1; conversely, if you're at address 1 a -1 click will roll the
address over to 128. Holding S1 down rapidly scrolls through the addresses.

5.After the new address has been set, you must wait approximately 30 seconds. There is a
timer in the controller's firmware that assumes that after 30 seconds of inactivity (no address
clicks), the entered address is the desired address for that controller. When the 30-second
timer expires, there will be a beep-beep indicating the controller has recognized and
accepted the new address and the address LEDs will turn off. If an Alpha/Numeric Display
is connected to the controller, "UNIT ##" will appear on the display (where ## is the control­ler's address).

NOTE: If an electronic locking device (such as a magnetic lock, door strike, or similar device) is to be
driven by the same power supply as the PXL-250 controller, please ensure the power supply provides
enough current to drive every device connected to that supply plus an adequate safety margin. AC
power cannot be used.
