8.3 COM1 Operating Modes
The
COM1
port can operate in one of several possible modes. From the
user's perspective, it
can be considered to be in Data mode or Manage-
ment mode, where user input can be accepted via either a menu inter-
face, a command line interface, or a diagnostic interface such as GE
MDS-proprietary DLINK protocol. The list below shows all possible
modes for the
COM1
port:
•
Console mode
—For serial-based “console terminal” control of
the radio. Menu screens are presented where you make selections
and apply them with the PC’s keyboard.
•
Data mode
—Where
COM1
is used for payload data, and not user
control/management of the transceiver.
•
DLINK (diagnostics) mode
—Where a PC running InSite or
PulseNET management software is connected to
COM1
.
•
Command line/scripting mode
—Where text-based commands
are used to manage the radio, typically by means of an automated
“scripting” system, rather than by manual entry. (Refer to
SD
Serial/Telnet Management Supplement
, Part No. 05-6193A01 for
a summary of text commands.)
Changing COM1 Modes
The
Device Manager
may be used to change the
COM1
operating mode
by accessing the
Configuration>>Communication Ports>>Com 1 Port Settings
screen (see “COM1 Port Settings” on Page 67). Using this screen, the
Startup Mode
and
Current Mode
may be set to either
Console
or
Data
from the
drop-down selections.
NOTE:
The COM1 operating mode may also be set using a PC
terminal connected directly to the port. See
SD Serial/Telnet
Management Supplement
, Part No. 05-6193A01 for details.
8.4 Implementing Sleep Mode
Sleep Mode places the transceiver into a low power “hibernating” state,
with a nominal current draw of less than 12 mA (at 13 Vdc) and a
“wake-up” time of approximately 50 milliseconds. Sleep Mode is often
used at battery/solar-powered sites to conserve power.
The ability to enter Sleep Mode is controlled through the
Device Settings
Screen (see “Device Settings” on Page 46), but an active low on Pin 4
of the
COM2
port is what actually places the radio in Sleep Mode.
NOTE:
Sleep mode is not intended for use on a Master radio.
