Communication with External Devices

When operated with the proper cable, the DFS offers a variety of output and input abilities for bi-directional communication

with external devices such as computers and data loggers.

Output Selection

There are three output selections:

• RS232

• Digimatic

• None

Although there are only three output options, there are actually four outputs available; consult the chart below to
