Page 94 MRC-565 Packet Data Radio Operations & Maintenance
The 565 cannot look back in this file in real-time to re-transmit old SDATA reports as of the
initial software release, but that could be implemented in the future if/when required.
5.9.5 User Interface
The MRC-565 has a RS-232 communication port for local user interface. If the breakout cable is
supplied, the 9-pin connector labeled “MNT” is the correct port. A direct connection to the front
panel of the MRC-565 USB connector can be used with a proper USB/RS-232 adapter cable.
A terminal server program, such as XTERMW.EXE provides a text-based operator command
interface to the radio Operating system. The commands required to operate the SDI-12 capability
are documented in the next section. There is a HELP command to list all commands, then the
HELP,xxxx command will give a brief description of each (xxxx) command.
A “transparent” user command is provided to let users configure their sensors if that is required.
This command takes any command format and passes it to a sensor on the SDI-12 line. The first
character of the command is the sensor address.
See the SDI,CMD,xxxx… command in the next section. This capability gives a technician the
ability to visit a site and perform some (maybe not all) diagnostic operations without
disconnecting a sensor or using the sensor Manufacturers software to communicate with the
sensor.
Since all user commands are also capable of being sent from the central host system to any radio
in the network, these commands can provide some unscheduled manipulation and status
interrogation of the SDI-12 sensors. In a Meteor burst system the use of remote commands may
require additional software such as XTERMW.EXE, DATACENTER.EXE or DDD.EXE. These
are documented elsewhere.
