6.6.2. Power Control Options
Coastal Environmental Systems' Standard Indoor Battery Charger DOES
NOT supply enough power to supply a radio during transmission.
Coastal Environmental Systems recommends use of a battery with sufficient
amperage or other power source to supply both the ZENO
®
-3200 and a
radio.
Since radios require considerable amounts of power, Coastal Environmental Systems designed the
ZENO
®
-3200 so that power to a radio can be controlled in several ways. Depending upon the type of
radio used and the amount of available power needed, the following table illustrates radio power control
options:
Power Control Option Reason for Using Option Typical Source of Power
Leave the radio on at all times.
This is only good when you
have unlimited power and you
are using a bi-directional radio.
Pin 25 on Auxiliary Serial Port.
(This is on whenever the ZENO
®
-
3200 is on.)
Only turn a radio on when it is
time to transmit data.
This is done typically with
unidirectional radios.
Pin 13 on Auxiliary Serial Port.
(+12 VDC Switched Voltage A,
controlled using Power Control
Menu.)
Turn the radio on for a specified
length of time on a regular
schedule.
This is done typically with bi-
directional radios.
External relay controlled by a
Digital Output via the Digital
Control Menu.
A Switched Voltage can provide enough power to supply a unidirectional
radio but not a bi-directional radio.
6.6.3. Controlling Unidirectional Radio Power (The Power Control Menu)
Typically, you will control power to a unidirectional radio using +12 VDC Switched Voltage A, which is
directly available on the Auxiliary Serial Port.

To do this, you need to specify which switched voltage
