Diagnostic Connections

HiPR-900 units continually monitor and report on their environmental and operating conditions. The di-
agnostic information is in TCP format and is available via any telnet session to port 6272.
Transmission of online diagnostics may be enabled or disabled at any station or stations without affecting
their ability to communicate with other stations. Diagnostics can be sent anywhere, including being back
hauled. Back hauling adds to the network traffic flow and must be taken into account in designing a net-
work. If a return flow is necessary, it needs to be reduced substantially to have a minimal effect on the
network as described in section 6.7.2.5.1.0.
The HiPR-900 radio modem can support up to 4 diagnostics socket connections at once. This may be
used, for instance, to carry out monitoring at a main office and at up to three separate field locations. It is
also possible that one of the four connections use a serial port instead by enabling it on the HiPR-900's
web browser interface.
More information, statistics, and offline test facilities are available via the browser. RF paths can be mo-
nitored and checked from either end of a link, without traveling to the other station.
6.7.2.5.1.0 Parameter
Adjusting the return diagnostics flow is done via parameter. This parameter indicates that only one out of
every x packets delivered will generate an online diagnostic message. The "thinning value" can be ad-
justed using the web interface (see paragraph 6.7.2.5) and set as follows:
♦ 0
off
♦ 1
every packet delivers a diagnostics message
♦ 1000 every 1000th packet delivers a diagnostic message
6.7.2.5.1.1 Output Format
Output format is man / machine-readable, ASCII, comma-delimited format. Reader program used (or
written) must ensure to decode two
changes will be required to the user online diagnostic reader program when the HiPR-900 radio modem
gets updated. The types are distinguished by "type field". At the present time there exist two types: type 3
and type 4. More types may be released in the future.
6.7.2.5.1.1.1 Type 3 outputs contain the following fields:
♦ Source MAC Address (Bridge mode): Hex numbers format [00:01:02:03]
or
Source IP Address (Router mode): Dotted decimal format
[111.222.333.444]
♦ Type of report: Decimal number (3) that identifies the report as a "type 3".
♦ # of fields: Decimal number indicating number of comma-delimited fields to follow
♦ Thinning value: Number of data packets before a diagnostic message is delivered

Previous versions of the HiPR-900 radiomodem had only one "type field"-type 0. If working with a combination of cur-
rent and previous versions of HiPR-900 units, the Reader program used (or written) must ensure to decode three sepa-
rate types of unit's diagnostic output (type 0, 3, and 4). See Appendix 2 for more detail.
