Specifications

Operation

Proximity cards are presented to the front of this  ID long distance reader. The beeper sounds when the proximity cards is read and  the message is transmitter the Host computer or interface panes.


Trouble Shooting

When powered up, the reader take a self-test to  ensure the best reading performance with the buzzer beeping continually. when  the self-test ends, the buzzer will give out a bug beep and the Reader enter the  normal working mode. If the buzzer continue beeping without stop for a long  time, please turn off the power and check out environment and power supply to  ensure locating the reader in a good working condition. In case of problems the  following procedure should be followed:

Failure to finish self-test with the buzzer beeping continually or with a short  reading distance

1. Turn off the power to the reader

2. Check the power input connections making sure that they are not reversed

3. Check the power supply complying with specification

4. If the supply has a current limit , set this to 350mA

5. Make sure to install the reader A in a environment without large area  conductors nearby a mounting on a conductive surface. In self-test state , do  not apply any tags in reader‘s functional area

6. Try to change the installment of the Reader 5150 to another place to check if  the trouble still exists

Radio Frequency Interference

Motors and electronic devices generate RF noise  that may interfere with the reception of the signal from a transponder. The  affect of RF noise is typically a reduction of read range. The idea Reader A is  susceptible to RF interference, as are all devices that receive RF signals. The  read range is affected by the amount of interference(noise) in the area. Common  sources of RF interference are power supplies, electrical and electronic  equipment, some types of lighting ,computers and monitors, motors and  generators. Moving the reader to a location known to be free of interference and  testing read range there will help to isolate RF interference as a factor in low  read range situations.

The Reader should not be mounted within six feet of any monitors(VDTs or  CRTs)because the scan frequencies of most monitors include frequencies that may  interfere with signal received from the access control cards.


Mounting:

Mount on non-metallic surfaces for optimal read  range performance.

Diagnostics:

On reader power-up, an internal self-test routine  checks and verifies the setup configuration, determines the internal or external  control of the beeper, and initializes the reader' s operation.

Indication:

When a proximity card is presented to the reader,  the beeper sounds.

Indoor/outdoor design:

The reader sealed in a rugged, weatherized epoxy  resin enclosure designed to withstand harsh environments as well as provide a  high degree of vandal resistance for reliable performance anywhere.

Power supply:

The reader can be operated over the full range of  11.0-15.0 VDC. If the reader power overrun 15VDC is applied, can't be operated,  or If AC power is applied, circuit damage can result,12VDC linear power supplies  are recommended.

Noise from devices such as switching power supplies, computer monitors, and arc  welders can reduce the read range or make the unit inoperable. Keep these  devices at least 10 ft away from the reader, With the Reader and power supply  wired together, apply power to the reader.

CAUTION:

12VDC linear power supplies are recommended.  Failure to provide an adequate current capacity power supply will result in  reduced read range or circuit damage.

Read range will be reduced if located on metal surfaces or in the vicinity of  metal objects or metal is installed nearby or the affect of switching power  supplies, computer monitors, electrical and electronic equipment, motors and  generators etc.
