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 Board via RS-232C or RS-422A/485 cable.

Note All sequences in this appendix operate on memory bank 0 and cannot be used for other memory banks.
