MaxID RM100 RFID reader interface
Project - RFID ID1170 Version 0.1 18 October, 2005 Page 11 of 24
6.2 Hardware Requirements
6.2.1 Power supply
The RM100 module was designed to run either from a 3.7V Lithium-Ion battery or
from a 3.2V to 4.2Vdc power source. The maximum current requirement is 1.5A
6.2.2 Data Terminal Equipment (DTE)
The RM100 module uses asynchronous communication to communicate to 3
rd
party equipment. The baud rate, parity and data bits are user selectable, with
38400,E,8 shipped as the default values.
Only RXD and TXD data lines are used, no hardware flow control necessary.
It is up to the OEM to provide a carrier board for the RM100 module. This carrier-
board must connect to the 10-pin connector on the RM100 module. This 10-pin
connector is used for asynchronous communication, LED’s and the for the power
supply interface. See figure below for pin-outs.
