Our handheld serial data
analysers have the ability to be upgraded
with new operational features after they have been sold. This is achieved by
means of “firmware upgrades”, released by New Forest Electronics every few
months.
Wherever
possible, the latest features added to the analyser are made available for
earlier models. For instance, timestamping can be added to any model
handheld analyser, including the original SDA-01.
Sometimes particular features cannot be added, because
the earlier models do not have enough program memory or appropriate
circuitry. Please see the table below, or contact us to confirm what is
possible.
(For details of the latest firmware
upgrade, click here, and
use your browser back button to return)
The
standard procedure is to return your analyser to us, and we will fit the
upgrade and carry out a functional test. Turn around is usually one working
day, and the UK cost is £49 plus £8 for next day return delivery. (An
upgrade is free for analysers bought within the last 12 months).
Alternatively, for overseas customers
with basic technical resources, we can ship the firmware component with
fitting instructions. This saves the analyser having to be returned to the
UK.

Example: A handheld analyser model SDA-02
with serial number 97045 could be upgraded with the firmware features listed,
except for Modbus over Serial Line or Online Download. However its maximum speed would remain
at 57600 bps, because the new maximum of 115200 bps is a hardware feature.
