protection is provided but it is not intended to protect the module in case of a
sustained over-voltage / lightning condition.
6.3.4.1 Power consumption
Power consumption depends on a variety of factors such as transmit power, input voltage
and data rate. The table below summarizes the power consumption of the module at an
input voltage of +12 V DC. All currents are in mA, and include the DC power
consumption of the DRA antenna receive section.
The receive current consumption is with the receiver on all the time. These numbers will
be a much lower number when slotted mode paging is activated, in the Fall of 2000.
Table 6-1 Module DC Power Consumption estimates at 12V DC Input:
Mode Minimum Typical Maximum
Shutdown 1.2mW 2.4mW 3.6mW
Standby(Receive only) 1.2 W 1.8 W 2.4 W
Transmit (minimum) 3.6 W 4.8 W 5.4 W
6.3.4.2 Power On
Power on is controlled via OR’ed DTR signals from any Port (Data, Control or
Diagnostic). Upon successful Power Up, the Module asserts the DSR line to let
user know that it has booted up successfully and is ready to accept commands etc.
6.3.4.3 Power Off
Power off is controlled by the module processor being completed with all software
tasking, and AND all DTRs being inactive. The module will de-assert DSR when all
DTR’s are seen as inactive, and all SW processing has concluded, informing the
application it is safe to shutdown power.
Note DSR/DCD will also go inactive in case of a fatal failure during re-boot.
6.3.4.4 Hard Power Reset
Provisions are included to “hard reset” a “stuck-up” module under user control:
equivalent to power cycling (see Pin 25)
6.3.5 Diagnostic Monitor Port
The Diagnostic Monitor Port consists of a single DB-9 male upright
connector, located on the right side of the module drawing Figure XX.
