Micro RWD QT Module specification

Parameter

Typical Value

Supply Voltage

5-volts (+/- 10%)

Operating temperature

-40 deg C to + 85 deg C

AVERAGE current consumption. (1 second polling)

10mA

Active period for RF AND host communication (each

polling cycle).

Up to 40 mS

Peak antenna voltage (optimum tuning)

100 volts peak-to-peak

Peak antenna current (optimum tuning) for short period each

polling cycle (up to 10 mS burst)

150 mA

Polling Delay

0 – 600mS

Current consumption during Polling delay

5mA

Maximum data rate (between card and RWD)

4k baud

Range (dependent on antenna dimensions and tuning)

Up to 150mm

Auxiliary output drives

Up to 25mA

Serial Interface

TTL level RS232

Serial Communication Parameters

9600 baud, 8 data bits, no

parity, 1 stop bit protocol

with CTS handshake

Basic electrical specification with LEDs pins and auxiliary outputs NOT connected.

During the “Polling Delay” period the logic levels on the RWD pins remain active and so for

minimum current consumption, the LEDs and the auxiliary output drives must be

disconnected.
