MS Series Reader Quick Reference
5.2 Connecting to the Design 5 PXL-100 – TB2
This Quick Reference is designed for the experienced installer as a basic reference while
installing MS Readers to ensure all connections are made properly. For detailed information on
installing an MS Series Reader, see the MS-3000 Quick S tart Guide
Quick Start Guide (P/N 01815-004), MS-5000 Quick Start Guide (P/N 01815-002), MS-7000
Quick Start Guide (P/N 01826-001), MS-9000 Quick Start Guide (P/N 01827-001).

1.0 Cable Requirements
1.1 MS-3000, MS-4000, and MS-5000
• up to 500 feet using six conductor, shielded, stranded AWG 24 wire (such as Belden
9536)
1.2 MS-7000
• up to 250 feet using six conductor, shielded, stranded AWG 24 wire
• up to 500 feet using six conductor, shielded, stranded AWG 20 wire
1.3 MS-9000
• up to 100 feet using six conductor, shielded, stranded AWG 24 wire
• up to 250 feet using six conductor, shielded, stranded AWG 22 wire
• up to 500 feet using six conductor, shielded, stranded AWG 18 wire
2.0 Grounding
Shield (Drain) continuity must run from the reader to the access panel. Shield (Drain) and
reader ground must be tied together at the access panel and connect to an earth ground in one
place.
3.0 Power
A reader may be powered by the access panel, so the reader is powered on when the access
panel is powered on. However the best case is to power the readers by a separate linear power
supply. When powered, verify the voltage at the reader meets the reader's requirements (refer to
Table 1 on page 3). When the reader is powered on, its beeper beeps in the following pattern: 3
short beeps, 1 long beep.
4.0 Operating Voltage
• MS-3000, MS-4000 operate using between 5v to 14v DC @ 50 mA
• MS-5000 operates using between 5v to 14v DC @ 100 mA
• MS-7000 operates using between 11v to 14v DC @ 200 mA
• MS-9000 operates using between 12v to 24v DC @ 200 mA

8.0 Troubleshooting the Reader Installation
Problem Probable Cause Corrective Action
The reader does
not recognize a
card/tag.
The reader has a
short read range.
1. One or more of the
reader's wiring
connections are incorrect.
2. The reader is not
receiving proper power
from the controller.
3. The reader is mounted
too close to a device that
radiates electromagnetic
interference.
4. A jumper is not set
correctly on the
controller.
5. You are using an
incorrect type of card.
6. The reader is unable to
read the card.
1. The reader's controller is
not properly grounded.
2. The shield wire for the
reader's cable has opened
somewhere between the
reader and the controller.
3. The reader is mounted
too close to a metallic
object (only MS-5000,
MS-7000, or MS-9000).
4. The reader is mounted
too close to a device that
radiates electromagnetic
interference.
5. The controller is mounted
too close to a device that
radiates electromagnetic
interference.
6. The reader is powered by
a switching power
supply.
• Power down the controller and verify the wiring
connections are correct.
• Verify the voltage supplied to the reader is correct per
the Operating Voltage
• Devices such as computer monitors radiate
electromagnetic interference that affects read range.
When possible, relocate either the reader or the device
to provide a greater distance between the two.
• For a PXL-250
and 2 of JP4 (refer to the Technical Reference manual
for more information - Keri P/N 01836-001).
• For a PXL-100
software, verify JP1 on the controller and the jumper
on the Receiver card
pins. If the controllers are using Doors
verify JP1 on the controller and the Receiver card are
not installed across both pins (typically the jumper
will be installed onto one of the pins to keep it
available).
• For an IntelliProx
pins 1 and 2 of JP1 (typically the jumper can be
installed onto one of the pins to keep it available).
• Make sure you are using an access card that is
compatible with the reader.
• Verify there is nothing that can interfere between the
reader and the access card.
• Ensure there is a quality earth ground connection
made to the controller. Refer to the controller's
documentation for specific information regarding the
earth ground connection.
• Verify the shield line from the controller to the reader
is one continuous, connected line. Refer to the
controller's installation documentation and verify the
shield line is correctly connected to the controller.
• Remove the reader from its mounting surface and
ensure there is no metal on the mounting surface
within 1 inch of the reader.
• Devices such as computer monitors radiate
electromagnetic interference that affects read range.
When possible, relocate either the reader or the device
to provide a greater distance between the two.
• Devices such as computer monitors radiate
electromagnetic interference that affects read range.
When possible, relocate either the controller or the
device to provide a greater distance between the two.
• Switching power supplies are EMI sources. Change to
a linear, regulated power supply .
