In the course of developing an ELK M1 driver, I encountered several typos and errors in the documentation (M1 Control RS-232 ASCII Interface Specification). Some of them were corrected (like the transposition of logical and physical zone status) in subsequent revisions whereas others continue in the current revision.
I posted the errors on ELK's forum and at least one of them has been corrected but several others persist.
This error has been corrected in revision 1.68:
Page 15: Alarm By Zone Request
The Zone Definition list indicates:
Carbon Monoxide='A'
Emergency Alarm='B'
Freeze Alarm='D'
Gas Alarm='E'
I think everything after 'Emergency Alarm' is incorrect because it skips 'C'. The Zone Definition list is repeated on page 41 for the ZD command and shows 'C' is assigned to 'Freeze Alarm' and not 'D'. Is this a documentation error or does the AZ command operate with a different Zone Definition list?
This is a new error:
Title Page Discrepancy
The title of the latest document revision states "ASCII Protocol RS-232 Interface Specification Revision 1.68 May 2, 2008". The footer states: "M1 Control RS-232 ASCII String Protocol Rev. 1.69 May 6, 2008". I assume R1.69 is the correct version.
This one remains in R1.69:
Page 5: "DK - Display KP LCD Data"
The "DK" command is listed but not documented in the manual. However, it sounds like another command "Display Text on LCD Screen (dm)". Is this a typo or a new (undocumented) feature?
This one remains in R1.69:
Page 25: "TC - Tasks Change Update"
The second line in the command's description is incorrect:
TC - Zone Change Message Command
It should indicate "Tasks" and not "Zone".
I'm not certain if this is an error:
Page 25: Keypad KeyChange Update
The Key Table list indicates:
LEFT KEY = 25
F6 Key = 26
F5 Key = 27
I haven't confirmed it but is it possible that the F5 and F6 keys are transposed? Whereas FK1 - FK4 are listed in increasing numerical order, FK5 and FK6 are not.
