3.12 ASCII Bidirectional Protocol
All the sample commands use address 1. If a different address is used it will need a different Check-Sum
calculated.
The instrument replies to the requests sent from a PC/PLC.
It is possible to set a delay time for the instrument before it transmits a response (see dELAY parameter in Section
2.9 on page 24).
The following communication modes available (see Section 2.9 on page 24):
• NOdU60:
• NOd td:
