Notice
Congratulations on choosing the N701-AT Quad Band GSM/GPRS modem
module.
Please read this User Guide thoroughly before use of N701-AT so that you
understand all of the features and functions.
Please note that use of unauthorized accessories and interfacing could cause
harm to you, your N701-AT or both and will void the warranty. Only use the
module in a way of AISA Tech User’s Guide and technical manual specifies.
AISA Tech reserves the right to make changes and improvements to any of
the products or accessories described in this guide without prior notice.
note) Some service providers do not support all of the functions described in
this User Manual. See additional documentation from your service privider.
Security
If your module or a model uses the module is lost or stolen, you must report it
to your network operator or service provider so that they can restrict the
module and model from use.
This is important, as you may be liable for the cost of unauthorized calls and
SMS, data transactions until the equipment is restricted.
You can help prevent such mobile phone crime by taking the following precautions:
- Don’t leave your module or model visible in a vehicle when you leave it.
- Make a note of the IMEI number. This number will be found on the bottom
side of the AVL.
Safety
Personal
- FCC regulations limit exposure to radio frequency (RF) radiation. To comply
with these regulations, operators of this device must maintain a distance of at
20 cm from the antenna. While the device is on, the
least
operator’s body and parts of the body such as eyes, hands, or head, must be
cm.or farther from the antenna .
- Operation of any radio equipment including N701-AT module and a model
uses it may interfere with the function of inadequately shielded medical
devices such as hearing aids and pacemakers. You must consult the
manufacturer of these devices or your physician, before use.
- Do not switch on your N701-AT in hospitals unless in areas where it is
clearly marked to do so. N701-AT continue to transmit call responses even if
left in stand-by mode. You must switch off when requested to do so.
- Do not move the antenna close to, or it to touch any exposed part of the
body when the N701-AT is turned power on; a damaged antenna may cause a
minor burn.

N701-AT Use
- Your N701-AT module produces magnetic fields. Do not place next to
magnetic storage media such as computer diskettes or credit cards when it is
powered on.
- Operating your N701-AT module close to other electrical equipment such as
televisions, phones, radios and personal computers, may cause interference.
Once again, please turn you N701-AT power off when entering a Hospital;
Medical Equipment can be affected.
- Do not expose N701-AT module to strong sunlight, direct heat or liquids
(such as water and solvent).
- Do not expose your N701-AT module to strong ESD (Electro Static
Discharge) since the ESD could result incorrect behavior of the N701-AT
module.
On the Road
- Before making or receiving calls, acquaint you thoroughly with the applicable
local laws and guidelines regarding the use of mobile radio device and
telephones and observe them at all times.
- Air safety bags, anti-lock brakes, speed control and fuel injection systems
are normally immune to radio transmissions but if you experience problems,
consult your vehicle dealer.
- Turn off you N701-AT module when refueling or where there are signs
restricting the use of 2-way radio equipment. Do not store or carry
flammable or explosive materials in the same compartment as your N701-AT
module.
Inside Aircraft
- Switch off your N701-AT module when in an aircraft. The use of
GSM/GPRS module/model in an aircraft may be dangerous to the operation of
the aircraft, disrupt the cellular network and is illegal.

Basic operation
Your N701-AT support GSM07.07(ETSI TS 100 916) and GSM07.05(ETSI TS
100 585) compatible quad band GSM/GPRS module with following proprietary
AT commands.
For more details of applicable AT commands and AT commands descriptions,
please refer to GSM07.07(ETSI TS 100 916) and GSM07.05(ETSI TS 100
585) Technical specification for detail.
-N701-AT proprietary AT commands.
a) AT+CPWROFF : power off the module.
b) AT+CGDATA=[<L2P>,[<cid>,[<cid>[….]]]] : Enter data state.
Command Possible responses
AT+CGDATA=”PPP”,1 CONNECT
Test command
AT+CGDATA=?
Note: Possible are protocols : “PPP”, “M-HEX”, “M-RAW-IP”. After entering
AT+CGDATA=”M-Hex”,1
the protocol can be used as follows:
Syntax : <int: counter><int: length[1-1500]><hex-sequence>[0-9-fA-F]
Examples:
- 1 200<CR> - send 1 packet with 200 0x2B (fill character)
- 5 1000<CR> - send 5 packets with 1000 0x2B (fill character)
- 1 5 31 32 33 34 35<CR> - send 1 packet with the given contents
- 1 10 31<q><CR> - send 1 packet with 10 0x31
Either a packet is sent
- if the length field is terminated with <CR>
- or the length value is equal to # chars of hex-sequence
- or the input is terminated with a character not equal to hex digit or <CR>
The session is terminated by default with +++, the context is deactivated.
If ct108 (AT&D) is equal to 2 and the selected L2 protocol is “M-HEX”, the channel is
switched back to idle mode but the context remains activated. Leave the layer 2
packet protocol by typing of +++.
It follows data transfer
or
CME ERROR:<error>
+CGDATA:”PPP”
i.e. +CGDATA(list of supported<L2P>s)
OK
