2.6 Installing GRP-520

If users want to start GRP-520 normally, it needs to follow these steps to install the

GRP-520 below:

A. Install the antenna

B. Plug in the normal SIM card (Before apply the SIM card, confirm it is OK by mobile

phone.)

C. Plug the Ethernet cable if you need it.

D. If you want to use the Micro SD card, please insert it into the slot.

E. Turn the rotary switch to 0 (normal mode). The COM1 will be the console in position 1

(debug mode), and the default username is “root”, default password is “root”.

F. Connect the DC.+VS and DC.GND to the power supply.

G. It is needed to wait about 20 ~ 30 seconds for OS booting. After finishing the process,

GRP-520 would be in normal operation mode and the OS LED would blank as heart beat per 1 sec.

H. It is needed to wait about 30 ~ 60 seconds to search the 3G/2G base and register to the

ISP. After finishing the process, the 3G LED would blank per 1 sec.
