• an external digital modem
recommended: Teledyne Isco's CDMA cellular modem
part # 60-5314-489
or GSM cellular modem part # 60-5314-563
Note
If an internal voice modem is installed, the sampler will use
that modem, and text messaging will be disabled.
When you enter each of the (up to three) phone numbers for the
sampler to call, if text messaging is active, a request for the TAP
(Telocator Alphanumeric Protocol) server number and communi-
cations parameters will be made.
As with voice messaging, the sampler will dial each telephone
number up to five times per alarm condition, until the message is
acknowledged.
Teledyne Isco offers a temperature sensor intended for use with
the 6712FR Refrigerated Sampler. The optional sensor connects
to the Rain Gauge port and uses I/O3 to transmit its temperature
readings to the 6712.
Note
If alarms are being used, the temperature sensor is simply
plugged into the panel mount on the one- or two-alarm output
module. Because the temperature sensor uses I/O3, it cannot
be used with a three-alarm output module.
To configure an attached temperature sensor, select "FR-TEMP"

HARDWARE SETUP screen. Select DONE and the 6712 recon-
figures its memory partitions to record the temperature
readings.
Temperature readings are updated approximately every 2.5
seconds. The readings are stored as FR-TEMP readings at the
data storage interval. You can retrieve a history of temperature
readings through the 6712's reports. The temperature data also
can be used as a sampler enable condition.
Teledyne Isco offers three analog outputs as a factory installed
option. The option is installed inside the controller and includes a
six-pin connector to interface with external devices.
The analog outputs can be programmed for either 0-to-20 mA or
4-to-20 mA operation. With the exception of rain, any parameter
that the 6712 sampler is currently measuring can be used to
control any (or all) of the analog output channels. Programming
the outputs requires parameter levels at each end of the analog
range and then assumes a linear relationship between those
points. MANUAL CONTROL of each output is also available.
