Installation and User Instructions for S831 Readers

Mount the Backplate

To mount the backplate:

1) Detach the main body of the reader from the

backplate by inserting a fingernail into the groove in

the bottom edge of the reader and swinging the

reader upwards.

2) Mount the backplate adjacent to the opening edge

of the door and at a convenient height. Feed the

cable to the reader through the backplate.

The S831 is a small-footprint contactless smart-card

reader, which uses p

. The S831 is able to read Texas

Instruments (ISO 15693) and Philips MIFARE smart

cards.

For either type of card, the S831 supports the use of

unencoded cards (where only the unique card serial

number is read). In the case of Texas Instruments (TI)

cards, an encoded card number can be read. Encoding

formats supported include TI's own formats and the

"smartMAX TI" format.

The reader can simultaneously support two different card

types/formats (e.g. "smartMAX TI" and MIFARE). The

reader is automatically configured to accept the first two

card types/formats presented.
