Regulatory Compliance
FCC
The modem was tested and certified to meet FCC Parts 15 in a stand-alone
configuration, which demonstrated that the TT8740 complies with Part 15
emission limits. FCC Part 22 & Part 24 is covered by the Enfora Enabler-IIG
"modular approval" process for a transmitter. This approach, described by FCC
Public Notice DA 00-131407 released June 26, 2000, is intended to afford relief
to equipment manufacturers by eliminating the requirement for obtaining a new
equipment authorization for the same transmitter when installed in a new device.
In order to use the GSM2000 TT8740 without additional FCC certification
approvals, the installation must meet the following conditions:
For the transmitter to meet the MPE categorical exclusion requirements of
2.1091, the ERP must be less than 1.5 watts for personnel separation distance
of at least 20 cm (7.9 in). Therefore, the maximum antenna gain cannot exceed
+3.3dBi. If greater than 1.5 watts exists, then additional testing and FCC
approval is required.
R&TTE The GSM2238 TT8740 modem has been fully tested and complies with all the
requirements of EN301 489-1, EN301 489-7 and EN60950-1:2001. Compliance
to EN301 511 has been demonstrated by testing on both the GSM2000 and the
integrated GSM0108 module.

9.5 Connecting the GPS Antenna
The GPS receiver inside the TT8740 provides power to the pre-amplifier in the GPS
antenna (Active-style) by applying a power of 3.3 Volts to the center conductor of the
RF input to the GPS receiver. If a passive-style GPS antenna must be used, please
verify that it has a DC block installed in order to prevent shorting to ground. The
GPS antenna connector on the TT8740 model is a FAKRA Blue connector. The GPS
antenna must be placed in an area where it can have direct view of the sky.

•
•
TT8740AN002 (1.00)
Copyright 2005, SkyPatrol, LLC.
Most GPRS configurations are Mobile Originate only.
The mobile TT8740 must initiate a conversation with a
remote server before the remote server can talk to the
TT8740.
IP addresses are dynamically assigned and can change.
Some IP addresses are NAT and are non-routable IP
addresses.
Page 33 of 45
SkyPatrol Evolution TT8740 User Guide
Revision 1.00
These issues are addressed with the following configuration
commands.
The examples will use the following information:
•
•
•
Modem ID/name = “MT_Test”
Remote Server DNS address = apitest.enfora.com
Remote Server IP port = 1721
11. Give the TT8740 a unique name.
•
TT8740AN002 (1.00)
Copyright 2005, SkyPatrol, LLC.
Send the following command: AT$MDMID=”MT_Test”
This command, combined with the wakeup message, will
allow the server to associate a Public IP address with a
specific TT8740 and create a window of opportunity
where the server can send commands to the TT8740

16 Additional Software Features
The following software features are included in version 0.6.0 and greater:
A user can send AT commands, via SMS, to the TT8740 in the following format:
Please refer to Enfora Application Note GSM0000AN022 – AT Commands Over
SMS.
The ability to store event data in memory, upon event trigger occurrence, and
transmit data when desired.
•
The user can configure the TT8740 to store event-generated data, to be sent over
the air to a remote server, in its internal memory. This feature can be enabled or
disabled using the AT$MSGLOGEN command.
•
“Total Number of Unread Messages” is decremented if an unread message is read
via the AT$MSGLOGRD command.
Example: Assume there are 50 unread messages in the GPRS queue and the total
number of messages in GPRS queue is 100. This means that the first 50 messages
have been read while the last 50 messages have not been read. If a user sends
AT$GPSLOGRD=0,1,51 then the total number of unread messages drops down
to 49 after successful transmission of that message. However, if a user sends
AT$GPSLOGRD=0,1,99 then the total number of unread messages still remains
at 50 – that message is transmitted to the remote server.
•
A user can also read a message that has already been read from the memory by
passing in the appropriate starting index number.
Synchronize RTC time with GPS time
•
•
•
RTC time is synched with GPS time automatically
RTC time is synched with GPS time every time the device is powered up and the
device acquires valid GPS data
RTC time is synched with GPS time every time the GPS time rolls over from
23:59:59 to 00:00:01
Allow a user to append RTC date and time at the end of event data
•
Bit-21 for Parm2, for output message types 40 – 42 & 45 (in AT$EVENT
command), has been added to allow users to send RTC time along with event data

Revision 1.00
•
•
•
The RTC date and time contains Year, Month, Day, Hour, Minute, and Second
fields
6 bytes of information is appended in Binary format when bit-21 is enabled. Each
byte represents an individual field
12 ASCII character (12-bytes) representing RTC date and time is appended in
ASCII format when bit-21 is enabled. Two bytes (or two ASCII characters)
represents an individual field
