Note:

z

V_1V8 (DC 1.8V@ 5% power Input)

This is the DC power supply input pin for GPS system. It provides voltage to module.

z

GND

GND provides the ground.

z

RXD

This is the main receiver channel and is used to receive software commands to the

board from SIRFdemo software or from user written software.

z

TXD

This is the main transmitting channel and is used to output navigation and measurement

data to SiRFdemo or user written software.

z

PPS (TIMEMARK)

This pin provides one pulse-per-second output from the board, which is synchronized to

GPS time. Need firmware supporting. If don’t used, can open.

Note: At present PPS function has not opened.

z

Power

Connect VCC_IN_1V8 pin to DC 1.8V. The power supply must add bypass capacitor

(10uF and 1uF).It can reduce the Noise from power supply and increase power stability.

z

Shutdown

Shutdown the RGM-2106 module, don’t remove the Vcc_IN_1V8 Pin, must be use on/off

pulse make it into Hibernate mode.(It’s will keep the Warm start and Hot start function

work well)

z

ON/OFF

Input pulse is required to start the system, and switch the operation mode tofull-power

mode or Hibernate mode.
