Issue
When swiping / presenting a card to a Wiegand card reader in Continuum it does not open the door.. When opening a Listview of Events the log shows "Card Bad Parity" or it reads an incorrect card number using Custom Wiegand.
Product Line
Andover Continuum
Environment
CyberStation all versions, with any of the Access Controllers - ACX700, ACX780, ACX57xx, NetControllers with any of the AC1 module range.
Cause
This fault is caused by incorrect wiring to the reader or choice of a 3rd party reader that is not compatible with Continuum.
Resolution
When wiring between a controller and a Wiegand card reader, all wires must be connected straight through to the corresponding terminal.
- Data1 to Data1
- Data0 to Data0,
- Gnd to Gnd ..............etc.
- See relevant controller installation guide for further details on reader wiring and cable types.
- On HID readers be sure to wire between the two Data 1 terminals and the two Data 0 terminals. Do not refer to the Clock and Data legend that is also on the controllers and many readers, as this is only used for ABA data connections.
- When using a separate Power supply for the reader, the 0V (Ground) terminal must still be connected back to the controller GND terminal to ensure both devices are working from a common ground potential.
- When testing out cards and readers always use a Listview showing a relevant Event log, as this will provide more information than the event view from the Door editor itself.
- To assist with troubleshooting data reads by the controller especially when using Custom Wiegand for non standard Continuum formats:
- Select only Custom Wiegand in the Door configuration.
- Rename the "AccessFormat" array if one has been created.
- Present a card to the reader.
- Check the Listview for Events as this will show the raw binary data string the controller is receiving.
- Compare raw binary data against the expected data from the reader used.
