6712 LTE Cellular Modem
Installation and Operation
Overview
This modem can transmit SMS text message alarms
to cell phones and/or email addresses, and receive SMS
text message commands, via the Internet.
Sampler firmware version 3.04 or newer is required for
the 6712 LTE modem. This firmware will only work with
C0 hardware.
To verify the hardware of your sampler:
1. Go to VIEW REPORT.
2. Select SYSTEM IDS.
3. The hardware version will appear in the display.
Equipment part numbers:
• 6712LTE Cellular Modem Kit
(modem module with magnetic mount antenna)
Part #60-9004-499 - Verizon
Part #60-9004-517 - Other
• Antenna Only Part #60-4804-035
Note
When the 6712 LTE modem is used, the baud rate is
locked at 9600bps. Ensure that this setting is also
selected in Flowlink or Hyperterminal.
Programming the APN
The APN (Access Point Name – for Data) is stored in
the 6712 Sampler head.
1. Plug the com cable directly to the 6712.
2. Connect with a terminal program and type ????
3-4 times to log in. The Sampler will beep.
3. When you see the “>” type “APN” then ENTER.
The following screen will appear:
4. Choose “1” to input the APN.

Step through the program, enabling any desired
alarms (I/O1, I/O2, I/O3).
Note
Three types of modems: TELIT (for CDMA or GSM or
LTE Telit modems), GELS3 (for GELS3 LTE modems),
and UMT (for older GSM modems) will be shown;
select the appropriate one.
Power Settings
Next, you will need to select one of three power on
modes, depending on your power conservation
requirements:
Power Always On – The modem stays constantly
powered.
Message Check – The modem powers on at
user-selected intervals to poll for valid incoming SMS
messages. If a message is detected, the sampler will
keep the modem powered up for the next 20 minutes,
ready to receive incoming messages.
Alarms Only – The modem powers on only to
transmit alarm messages.
Notification List
As detailed in the Extended Programming section of
the sampler manual, when any programmed and
enabled I/O output enters a true state, the sampler can
send an SMS text message to a list of up to three phone
numbers.
With the 6712 LTE modem, the sampler can also send
the message to up to three email addresses.
Email Setup
Email addresses are programmed into the sampler
with HyperTerminal.
1. Connect your computer to the sampler’s interro-
gator port with the standard interrogator cable:
Part #60-2544-044 for 9-pin serial port;
part #60-2004-508 for USB port.
2. In Hyperterminal, use the following communica-
tion settings:
• baud rate 9600bps
• no parity
• 8 data bits
• 1 stop bit
• VT100 terminal emulation
3. On the computer, press and hold the question
mark (?) until the sampler returns its banner
string. A caret (>) prompt will appear when the
sampler is ready for input.
Press Enter (CR) after every command.
4. At the prompt, enter the word "email." Then fol-
low the sequence shown in Figure below.
Note
A combination of phone numbers/email addresses can
be used. Any phone numbers already programmed for
I/O 1, 2, or 3 will appear in Hyperterminal instead of
the word “empty.”

SMS Commands
Commands to start the program, load a selected pro-
gram, enable/disable the sampler, take a sample, and
report sampler status, can be sent to the sampler by cell
phone or by email.
When you send a command to the sampler, it will
carry out the command and also respond with an
acknowledging message to all programmed destination
phone numbers/email addresses.
With a cell phone, simply send the command in a
text message to the 6712 LTE modem’s phone number.
When using email, send the command either in the sub-
ject line or body of the email, to:
[phone number]@vtext.com.
The command must contain the string “6712,” along
with one of the commands listed in Table 1. The middle
and right columns are interchangeable, with the right
column containing abbreviated commands. Commands
are not case-sensitive, and do not require spacing.
Example Command: 6712status
Shortened Version: 6712C9SMS Messages Sent From
the Sampler
Response messages and alarms sent out by the sam-
pler contain the sampler’s three-digit ID number, the site
name, and IP address (if applicable), followed by either
the command response or alarm condition.
Example Response:
ISCO Sampler 148, FACTORY148, IP:##.###.###.###,
Sampler Status: Program Done
Example Alarm:
ISCO Sampler 148, FACTORY148, IP:##.###.###.###,
alarm 1 PGM ENABLED
To acknowledge an alarm, copy the text and send it
back to the sampler. This will stop the user from
receiving the same message up to five times.
Dual Sampler Setup
To set up a dual-sampler system where one sam-
pler’s program is triggered by the enable alarm of
another, program the primary (master) sampler to send
an SMS alarm message of "Program Enabled" to the
phone number of the secondary (slave) sampler.
Program the secondary sampler to start with a delay
setting of WAIT FOR PHONE COMMAND.
SIM Card
The data transmission capabilities of the 6712 LTE
are dependent upon the type of service plan you have
through your cell phone service provider. The service
parameters, or provider, can be changed by simply
replacing the SIM card in your 6712 LTE. Check with
your service provider to verify what data transmission
technologies are available for your use. There are three
types of SIM cards, but only the Micro SIM cards will
work with the 6712 LTE modems (Figure 1).
Note
A Micro SIM card is required for any LTE units
including the 6712 LTE.
