JO-DataClient - Terminal software for CHM15k
measure period and approx. 2 MByte program file a whole update process con-
sist of approx. 1000 blocks and therefore lasts more than 8 hours! However, the
update block size can be raised with the variable UpdateBlockSize up to and
including a value of 32,768 byte, this parameter can be changed by the set com-
mand from section 2.1. However, it must be clearly warned that a single block
transmission of 32,768 byte lasts about 12 seconds at transmission speed 38400
baud. So one has to think (and calculate) carefully about possible combinations
of measure period, raw telegram mode and update block size before changing
this parameter – at current time there is no lock in JO-DataClient to prevent users
from choosing dangerous parameter combinations!
Important Remark:
Update operation is only permitted in ServiceMode. Therefore this service mode
must be initiated before starting the update:
There is an additional button "get all parameters" on this page (not related to
software update) for this purpose:
All parameters of the CHM15k will be saved into the local text "file save filename
for parameter file".
