contact the SAMSUNG Customer Service near you.
Problem Action
Can I specify RF only or RF+P/W
mode differently according to the
card?
1) It is not available.
2) The mode is defi ned for each reader device, not the card.
Thus, you can not specify the mode for each card differently.
Ever since I mass-transferred data
using the PC application, some
cards are not allowed for access.
1) You might have not saved card information to the PC, but just to the device
when registering card using the PC application.
2) Check if there is a registered, but disallowed card in the PC.
3) For an unregistered card, try to enter it again and save to the PC before
transferring to the device.
4) The Mass Transfer/Group Transfer function of the PC application will delete
all card data in the device before transferring the PC data to the device. As
such, if you usually register one card on a daily basis, you may not save it
to the PC but transfer to the device, which causes unsaved card numbers
not to be registered with the device in the operation of a mass-transfer.
5) If this is not the case, the problem may be caused by the defective of an
internal circuit.
Contact the nearest customer service for technical assistance.
The RF card works normally, but
the key input (for the card number)
using the keypad does not work
properly.
Use the provided software program to check the use of the keypad while the
reader is operating in a certain mode.
Enable the use of the keypad before downloading data to the device.
The reader reads a card normally
but no reaction is made by the
device or an irrelevant card number
is displayed.
1) Check the power source of the reader. (Check if the LED indicator of the
reader is blinking when it has read a card.)
2) Check if the reader works properly. (Disconnect the reader from the system
and use a measuring device such as an oscilloscope to measure the output
port of the reader.)
3) Check if the reader is properly connected to the system (device).
- Check if the Wiegand communication lines between the reader and the
system are properly established. (D0, D1)
- The Wiegand communication line should be connected to GND. (A
different power source may be fi ne but the earth-grounding point should
be connected to GND of the device.)
4) If you fi nd the output signal from the device but with severe noise when
using a measuring device to measure the Wiegand communication line,
please check the followings:
- Connect the shield wire and the spare wire of the cable to GND.
- Use the repeater.
5)
If the problem persists after performing all the checkpoints above, contact the customer
service for technical help.
