Appendix F
E5ZE Temperature Controller Write Protocol
The E5ZE Temperature Controller Write Protocol writes and controls various settings in remote mode for the
Temperature Controller connected via a RS-232C or RS-422/485 cable from the PC via the Serial Communica-
tions Unit/Board.
Note 1.
Negative values cannot be written. All values must be set as unsigned BCD.
2.
All sequences in this appendix operate on memory bank 0 and cannot be used for other memory
banks.
