Temperature data logging
with the DS1621
Temperature Sensor
Download this file ‘direct
to com1’, plug a null modem cable into COM1 on your PC, run
‘Hyper Terminal’ and open the file ‘direct to com1’.
‘Temperature=00##’ will then be displayed and the value
will be updated every two seconds.
' Example : DS-IM II DS1624/DS1621 Temperature sensor (optional) reading
'
' Read the current temperature @ 1oC accuracy and send to a RS232 device
connected
' to the DS-IM II RS232 port every two seconds e.g. PC (null modem cable
required)
