Appendix E
E5ZE Temperature Controller Read Protocol
The E5ZE Temperature Controller Read Protocol reads and controls various parameters in remote mode for
the Temperature Controller connected to the Serial Communications Unit/Board via RS-232C or RS-422/485
cable.
Note All sequences in this appendix operate on memory bank 0 and cannot be used for other memory banks.
