Installation and User Instructions for S821 Readers 1 Mount the Backplate To mount the backplate: 1) Detach the main body of the reader from the backplate by releasing the two securing screws along the bottom edge of the reader. 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 backplate has suitable holes for connection to most standard electrical backboxes. The S821 is a contactless smart-card reader, which uses p. The S821 is able to read Texas Instruments (ISO 15693) and Philips MIFARE smart cards. For either type of card, the S821 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. TM 20mA current loop seudo-random communications ®® 9600-0304.Installation and User Instructions for S821 Readers, Issue 1.0x8 8th October 2003.AMAG Technology, 2003. FCC Notice:This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Any unauthorized modification to this device may void the authority of the user to operate it. All trademarks acknowledged. Texas Instruments is a trademark of Texas Instruments Incorporated. Philips and MIFARE are registered trademarks of Philips Electronics, NV. © Specifications Input voltage: 9-14V. Input current: 110mA @ nominal 12Vdc supply. Operating temperature: -13 to 158 F (-25 to 70 C). Operating humidity: 15 to 90%, non-condensing. Maximum read range: 3" (80mm). Approvals: EN50133, R&TTE, IP656. °° 4 Using the Reader Present the card face-on to the reader until you hear a "bleep". If the green indicator is lit, the card has been accepted and the door is unlocked. If the red indicator is lit, either the card has not been accepted, or you do not have access through the door. If the read and green indicators flash alternatively, please wait. cards can be presented in rapid succession - there is no need to wait for the green or red LED to extinguish before presenting another card. Note: 2 Reader Connections 20mA Current Loop Reader Connections 0V Connect shield at controller end only (connect to case) Tx- Tx+ Rx- Rx+ 12V Controller connections (20mA reader port) Red Black White Blue Green Orange Note: the brown wire is not used Reader The reader supports the first two different card types/formats presented after power-up. For example, unencoded MIFARE and encoded TI cards (in this example, unencoded TI cards would not be recognized). The reader enters this configuration mode whenever power is re-applied. 3 Reader Configuration
