- 12 -
5.1.2.2 SMS Center Number
SMS Center Number(Primary SMS number) is used for getting the alert message/position data/reply
message by SMS.
The difference between SMS center Number and VIP number is that SMS Center Number can get location
data.
Note:
1) If the working mode is GPRS mode(standby/timing/vibration), SMS center number only be used for sending
short message command and receiving the reply of short message command .
2) If the working mode is SMS mode(standby/timing/vibration), SMS center number is used for getting the
position data/alert message/reply message.
5.1.2.3 VIP Numbers
VIP number is used to get the alert message /reply message from JT600.
CALL Ⅰ: Set the index 1 number
CALL Ⅱ: Set the index 2 number
Note:
- 13 -
The first time you sent short message command to JT600,this cell phone number would be preset to CALL Ⅰ
number.
Only when the cell phone number is one of the VIP numbers and SMS center number, Can this number send
short message command to JT600.Otherwise, the short message command would be omitted by JT600.
5.1.2.4 GPRS network parameters
Refer to the default information. It‟s just a example. APN : access point name at local. CMNET is in china.
And Please note:
