Mm-R32

Outdoor proximity reader

General device description

The Mm-R32 reader is destined for transponder (proximity cards) readout. It works at 125kHz frequency and reads Unique type transponders with Manchester coding. The reader cooperates with devices which support the RS232 serial port (computer, controller, etc.)by sending them card numbers.
The reader has a durable and aesthetic casing made of a shock-proof polyamid. All electronic components are flooded in vepuran which makes the reader resistant to atmospheric conditions. That is why it can be used both in- and outdoors. Its small dimensions allow installing it virtually anywhere.

Identifiers

The Mm-R32 reader reads UNIQUE type transponders. Typically transponders are plastic cards, on which it is possible to print a company logo, an employee's photo or other information.

The transponders can also take other shapes like key-fobs, watches, cylinders, etc.

Communication

The reader sends the code of the read card as a set of ASCII codes through the serial RS232 port to the connected device.

A detailed description of how to connect the reader is presented in the reader's data sheet.

Configuring the reader

The Mm-R32 reader can be configured according to the user's demands. Configuration includes setting the readers work mode and transmission format.

A proper reader configuration can be set up manually using the bibiCOM programme (Windows®98/2000/XP) provided on a CD along with the reader.

Reader's work modes

• OnLine
  In the OnLine mode each time a card is brought close to the reader, the event is signalled (LED, buzzer) and the card's code is sent to the computer once.
  If the option "Signal if card away" has been selected in the configuration, the reader sends an additional code the same moment the card disappears from its field.
• OffLine
  In the OffLine mode the red diode does no blink - the reader does not react to cards if they are placed in its field. Only after a command to read a card is sent from the computer the reader is activated.
  If there is a card in the reader's field and its code has not been sent yet, it will be done immediately. In the other case the red diode starts to blink and the reader awaits for a card. If a card is brought close to the reader it reacts as in OnLine mode.
  After sending the card's code the reader becomes inactive again. To read another card it is necessary to send another command.

Data transmission

A transponder send 64 bits to the reader, but only 40 of those bits make its unique number. The other bits are used for synchronization and transmission correction checks. The read number is stored on 5 bytes which are sent to the computer.
Transmission format is defined during reader configuration. A single transmission frame consists of 4 fields:

• Beginning of transmission character [ * ] - option
• Reader number [8 hex characters between <> parenthesis] - option
• Card number in one of the following formats:
  • 10 hex characters (0..9, A..F) or 15 digits (0..9)
  • 14 hex characters or 21 digits (CRC mode)
  • The [ ^ ] character - a card has been removed from the field
  • Empty field - no card in the reader's field
• End of transmission [CR LF code] - option

An example of a full code: *<00140001>1CB47F38A9(CR)(LF)

Ordering

If the customer does not wish to configure the reader manually and wants to change the default settings, please specify the wanted configuration while ordering.
