The definition of cold start, warm start and hot start is described as following table:
Option Description
Hot Start The Evaluation Unit restarts by using values stored in the internal of the GPS receiver.
Warm Start (No init) This option has the same functionality as Hot Start except that Ephemeris data and
retains all other data.
Warm Start (init) This option clears all initialization data in the GPS receiver and subsequently reloads the
data that is currently displayed in the GPS receiver initialization is cleared.
Cold Start This option clears all data that is currently stored in the internal memory of the GPS
receiver including position, almanac, ephemeris, time, and clock drift.
To switch from SiRF protocol to NMEA protocol
(1)Select the “Action/Switch to NMEA Protocol” like follows.
(2) After you select the “Switch to NMEA Protocol”, it will show up a “Select NMEA Messages” dialog. Select
the NMEA Messages that you want to use.

(3) Determine the update rate for each NMEA
message
(4) Select the baud rate that you want to use from
the Baud Rate pull down menu.
(5) Click the OK button to save or Cancel button to
exit
(6) It will switch to NMEA protocol.
To Synchronize Protocol
When you don’t know what the protocol/baud
rate is set , you can use this option to synchronize
protocol. Select the Action/Synchronize Protocol
and Baud Rate. It will synchronize the protocol
and Baud Rate.
To Switch Trickle Power Parameters
from SiRFDemo.exe
There are two modes of low power operation:
(1) Trickle power: In TricklePower mode, the
power to is cycled periodically, so that it
operates only a fraction of the time.
(2) Push to fix: In Push-to-Fix mode, the receiver
is generally off, but turns on frequently enough
to collect ephemeris. So that, upon user
request, a position fix can be provided quickly
after power-up.
To enable trickle power mode from SiRFdemo.exe,
please select the “Action/Set TricklePower
Parameters” like following picture.

RoyalTek GPS Receiver RGM-2101/RGM-3000/REB-12R REV-2000 Operational Manual
19
Then, it will show a “TricklePower parameters”
dialog for parameters setting. There are two
parameters of Trickle power that needs to be set,
“Update Rate and On Time”. The “Update Rate”
means the navigation update frequency. For example,
“1 sec” means output once per second and “2 sec”
means output once per 2 seconds. The “On time”
means running time in the output period. For
example, “200 ms” means the running time is 200
ms per navigation update. The duty cycle of trickle
power is determined by setting of “Update Rate” and
“On Time”. For example, if the “Update Rate” is 1
sec and “On time” is 200ms, the duty cycle is
200ms/1000ms = 20%. If the “Update Rate” is 2 sec
and “On Time” is 300 ms, the duty cycle is
300ms/2000ms = 15%. The duty cycle is limited to
5% ~ 50%. Since it will do some estimation in
trickle power, please tune the proper duty cycle that
can compromise the power consumption and
acceptable navigation performance. The
“ricklePower Prameters” dialog is shown as
following picture.

20
To change TricklePower parameters
from 12 pins interface.
Since it is NMEA output default, it needs to change
to SiRF protocol before change TricklePower
parameters. The procedure is described as follows:
(1) Use “Set Serial Port” command of SiRF
NMEA input messages.
$PSRF100,0,9600,8,1,0*0C<CR><LF>
It will switch from NMEA to SiRF protocol.
(2) Use “Set Trickle Power Parameters - Message
I.D. 151” to set the trickle power parameters.
(3) Use “Switch To NMEA Protocol – Message
I.D. 129” to switch back to NMEA protocol.
To upgrade GPS engine board program
(1) Push and hold the BOOT button.
(2) Run the SiRFProg.exe.
(3) Select the Target Loader File. Select dltarget.s
for STAR1. Select dlgsp2.bin for STAR2.
(4) Select the Target file that need to be
programmed into flash memory.
(5) Select the COM port. Keep the Baud rate at
4800 for RGM-2101/3000 REB-2101 and
9600 for REB-12R.
(6) If you want to upload program to REB-2101,
please assert the GSP2 check box. But leave it
unasserted for REB-12R.
(7) Click Upload to begin programming flash
memory.
(8) Release the BOOT button.
(9) Now it will run the new program that uploaded
into flash memory.
