1.4 Communication
The standard communication interface is Ethernet with protocol IEEE 802.3 –
10/100 BaseT. other options are RS-232 / RS-422 / RS-485.
1.5 External Storage media
We have got two types External storage Media, SD card and USB for the recorder. If
the recorder is used with 6-channel inputs, an easy chart to show the maximum days
* The above is an approximation
Each record of data uses 2 bytes or 4 bytes of memory.
For ex: Selected data size = 2 bytes
If the Log Speed ( the recording speed of measured data ) is set to the fastest speed at
1 second per data, then for a six channels, 16GB SD Card will last approximately 15808
days [= 16GB / ( 2 bytes x 24 hours x 60 minutes x 60 seconds x 6 Channels ].
The following formula is to calculate how many days the USB disk could do saving
before it is full.
The ? days = (The capacity of SD card memory x Log Speed) / ( 2 x no. of hours per
day x 60 x 60 x Number of channels )
If the User is using USB to store data, To avoid losing recorded data while
transferring to PC, it is necessary to insert USB memory back again into the
recorder soon after loading recorded data onto PC.
