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.
