Connections Antennas 4 Antenna connections via R-SMA The PCB edge mounted R-SMA connectors used in the module. The Digikey part 142-0701-841 as the reference. NOTE: The maximum length of the coaxial cable (distance between reader and antennas) is 10m. NOTE: The impedance of all RF channels is 50 ohm. ODC interface ● ● ● ● ● ● Socket type: RJ-25 socket with top side lock tab location Voltage range: 10-24V Max unit power consumption from the ODC power line: 1.3W Max current through ODC bus: 1.

RFID Tags Supported Supports ISO15693 tags Outform development will focus on ISO15693 Anti-collision algorithm: up to 4 tags on the same antenna (for ISO15693 only) Indicator Lights PWR- device itself is powered and working ODC pwr- is on when ODC bus is receiving power ODC RX- blinks when device receives ODC command CFG- button used for assigning ODC address manually ANT 1, ANT 2, ANT 3, ANT 4- shows which antenna is connected and blinks every time the OSM RFID does a “pull request” to check if a tag is r

Passive mode (not in current release) The RFID module sends an event report only by RFID status request command. The RFID module Active mode (not in current release) The RFID sends reports while the tag(s) is(are) present on the antenna(s). The tag IDs are sent continuously, at the same polling cycle interval (approximately). Event Report mode (default mode) The RFID module initiates event report as an event appears: tag appeared or tag disappeared. One single command for every change.

o ● ● Device keeps information about the current antennas configuration and operating mode in external non-volatile memory and returns to the last configuration/mode after power up. See “External Memory Map” and “App’s settings” sections 0x003F – RFID read request 0x0040 – RFID reading The complete details about the Outform Device Communications (ODC) protocol are available in the ODC spec document.
