3.9 System Update
3.9.1 Instructions for System Update
When you upload new system software and the transfer fails never switch off the SMT-200 by
disconnecting the battery or powering down the Docking Station. You must let the SMT-200
time-out by itself. This takes about 1 minute.
The instructions for System Update are the same as for File Transfer except that the Docking Station
program asks you for confirmation when you’ve chosen this command.
Technical Note:
When downloading a file from PC to the SMT-200, the old version is put into the free memory first. If
transfer fails then it is restored. When transfer fails within a minute the SMT-200 will reboot. This is the
reason why it could be fatal
to interrupt a failing transfer by just switching off the power and/or
disconnecting the battery.
3.9.2 Failing System Updates
For possible reasons of failing transfer check the Failing Transfer in the file Transfer section. In
addition check that the version you are trying to upload is a later date than the one current in the SMT-
200. If it’s older it won’t be transferred.
3.10 The SMT-200 Geophone Specifications File
The file SPC.TXT is used by the SMT200. It can be changed so that it contains your own choice of
geophones. This can be done using the geophone specifications editor built into the Docking Station
software. Alternatively this can be done directly from the SMT-200. An example of the contents of a
SPC.TXT file is shown below.
"Sensor-SM24", 375, 10.00, 28.8, 0.250, 0.0020, 0.10, 12.00,11.0, 2.5, 2.5, 2.5, 2.5, 2.5, 2.5, 0.0, 5.0, 20.0
"Sensor-SM4", 375, 10.00, 28.8, 0.250, 0.0020, 0.20, 12.00,11.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 20.0
"Sensor-SM4-HS", 375, 10.00, 28.8, 0.250, 0.0020, 0.10, 12.00,11.0, 2.5, 2.5, 2.5, 2.5, 2.5, 2.5, 0.0, 5.0, 20.0
"Sensor-SM4-LD", 375, 10.00, 28.8, 0.250, 0.0020, 0.10, 12.00,11.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 20.0
TIP: If modifications to the geophone specification file are made from the SMT-200 these may be over-
written during the next data transfer session. It is better to modify the specs. in the Docking Station
program via the data transfer cycle to upload to the SMT-200.
