E Series Ethernet Radio – User Manual
Version 08-10
•
Backoff Timing – “Maximum Slots”, “Time per Slot”. This can
only be configured if the mode is “remote”. When a remote
is ready to transmit data but it detects a carrier signal from
the master set it holds back its transmission for a random
“backoff” time after which it tries to transmit data again. This
ensures that modems waiting to be allowed to transmit do
not re-attempt to do so at the same time. The “Maximum
Slots” (1 to 16) and the “Time per Slot” (1 to 255ms) are
used to calculate the backoff time by multiplying the slot
time by a random number between 1 and the maximum slot
number. For example if the time per slot is 30ms and the
maximum slots is 4, the random backoff times can be 30,
60, 90 or 120ms.
Unit Information
The information displayed is intended to assist the user to identify
the radio modem as well as support should their services be
needed.
Model Type refers to the type of unit. The ER45e is a remote
unit and the EE45e is a exciter inside a Ethernet base station
unit. Gen III will be noted where Gen III hardware is detected.
Freq Band & Bandwidth refers to the frequency band
supported by the radio as well as the channel bandwidth. For
example 51A02 is a type 51 band with a 25kHz channel.
Serial Number is unique to each unit and is set within the unit
at time of production as well as included on the label fixed to
the unit.
Firmware Pack
refers to the firmware package version
installed in the radio. There are several components
associated with microcontroller and DSP firmware installed
and a single version number is used to identify them.
Diags Installed is set to yes or no depending on whether the
diagnostics key has been set in the unit.
Unit Information (Details)
Part I – TVIEW+ Management Suite - Programmer
More detailed information is also available to assist in identifying
components installed in the unit (remote, base station or hot
standby).
The additional information provided is:
•
Controller Rev refers to the microcontroller firmware
component version for the radio.
•
DSP Code Rev refers to the DSP firmware component
version for the radio.
•
Processor Board ID refers to the processor board
identification number and hardware revision information for
the radio.
•
RF Deck ID refers to the RF deck board identification
number and hardware revision information inside the radio.
•
Production Build Code refers to the automated production
test and calibration sequence used during manufacture of
the radio.
•
Hardware indicates whether the radio is half or full duplex.
•
Unit Type indicates whether the unit is recognised as a
remote or base station.
•
Tx and RX Frequency Range indicates the frequency range
for which the radio is capable of being operated in.
In the case of a base station unit the following additional
information is provided:
•
Base Firmware Pack refers to the firmware package
version installed in the base station (front panel) controller
which is separate to the radio installed. There are several
components associated with this firmware package and a
single version number is used to identify them.
•
Base Controller Rev refers to the microcontroller firmware
component version for the base station.
