  Chapter 6. Serial Communications Checking the DF868 Baud Rate For successful serial communications, the DF868 and the personal computer must be set up to send/receive data at the same speed. To check the baud rate setting of the DF868, proceed as follows: Access the User Program, by pressing the [PROG] key on the keypad.

• Page 97: The Optional Rs485 Serial Interface

  Although the standard RS232 serial interface included with the Model DF868 is adequate for most applications, Panametrics offers an optional RS485 serial interface upgrade for special situations. The Model DF868 is easily modified to provide RS485 communications, and this section describes the wiring and use of the special RS232 to RS485 converter.
