MODEL 346 INSTALLATION AND OPERATION MANUAL

5.7.10 COMMUNICATIONS PROBLEMS

Assuming that the hardware and software configurations are correct, the following problems may arise.

1. It is essential that the correct case (ie. capitals or lower case) is used for the mnemonics as shown in table

5.7.5b. Failure to ensure this will result in a NAK being returned.

2. It is essential that the correct ‘leading character’ is used when writing an alpha-numeric or Hexadecimal string.

Alpha-numeric values MUST be preceded by an apostrophe (‘) and Hex values must be preceded by >. The

format tables 5.7.6a and b explain the various formats used. Failure to ensure this will result in a NAK being

returned.

3. If the wiring is incorrect (e.g. Tx + and Tx - crossed over) it is possible that the host will pick up a reflection, and

instead of ‘No Response’, a copy of the Enquire or Write message will be returned.

4. Before writing a value to a PV can be accomplished, the relevant channel’s function must be configured to

‘comms’.

5. Before writing to the instrument, Comms “Read/Write” must be set NOT Read Only.
