Hanging Bracket
The hanging bracket connects to the back of the iPack and allows
the assembled logger and iPack to easily be installed in or removed
from the shelter box using the keyed slots. The hanging bracket is
included with the shelter box.
iPack Connector
On the back of the SymphoniePRO logger you'll find the 25-pin
(male) connector for the iPack, which comes with a sticker over it
to keep dust and moisture out until it's mated with the iPack.
When ready to install the iPack to the logger, remove the protective water resistant sticker from the back of the
logger.
2.1.3 Channels
SymphoniePRO has (12) counters channels, (7) built-in analog channels, (7) P-SCM analog channels, and (2) RS-
485 (full or half duplex) channels. Each channel will configure itself based on pull-down list selections made in
the software.
Counter Channels 1 - 12
The twelve built-in counter channels are compatible with industry standard anemometers and tipping rain
buckets. A 12 V excitation is available for each channel. Signal type can be pulse or coil, and an internal pull-up
resistor can be turned on for reed switch signals. Channels 8 and 9 can be configured to accept high frequency
sine wave signals.
Analog 2.5 V or 5 V Excitation Channels 13 - 15
Channels 13 through 15 accept input signals from 0 to 5 V and are ideal for wind direction vanes and NRG
temperature probes. A user-selectable excitation voltage of 2.5 V or 5 V is available per channel. 2.5 V is a
reference voltage intended for use with potentiometer type wind vanes like the NRG 200P.
Analog 5 V or 12 V Excitation Channels 16 - 19
Channels 16 through 19 accept input signals from 0 to 5 V and are intended for use with NRG barometric
pressure, relative humidity, and temperature sensors. Each channel has a user-selectable excitation voltage of 5
V or 12 V.
Analog (P-SCM) Channels 20 - 26
Channels 20 through 26 accept SymphoniePRO Signal Conditioning Modules (P-SCMs) for adding analog sensors
such as high quality pyranometers and other meteorological sensors. Please check the P-SCM list below for
sensor compatibility. Signal (+) and Signal (–) are available for differential inputs on each of the seven channels.
