RS232 Protocol - Name Command

[harleydude]

I ran into a problem today with getting the names of the zones thru the serial protocol. I have zones 1-3 & 9 named. When I issue commands to get the names of the zones I get the name for zone 9 when I request the names for zones 4-8. Below is the results from a VB app I put together to test it. Zones 4-8 are set to the default.

Any ideas???

I'm going to take a guess here and guess that your zones 4-8 are disabled too. I noticed the same behavior with different zone numbers and it appears that when you issue the SD command on a disabled zone it returns the ascii name of the next higher enabled zone. Thats probably a bug, but at least I think I understand the behavior.

Spanky?

Yes, zones 4-8 are disabled. And not only does it report the name for the next highest zone but also the zone number.

Could move the motion to zone 4, but wanted to kind of group my device types.

Spanky, any thoughts?

Not a Bug, but a feature. The zone name scan routine enables fast retrieval of zone names that have permission to be viewed.

The zone must be enabled.

Use the SD command to find the first valid zone. Take the returned zone number and request the next zone.... and so on until a zone 0 is returned which marks the end.

Other names work the same way: Tasks, lighting, outputs... The first character of the name must be greater than a space character.

Guess I should have paid more attention to the manual.

If the first character in a requested name is a “space†or less, then the next names are searched until a name is found whose first character is greater than “space†or the “Show On Keypad†bit is set. If no valid names are found, a “000†for the NNN address is returned. This speeds up the loading of names so that invalid names are not returned. M1 version 2.4.6 or later.

Does the above apply to retreiving the Users?

When I try and retreive users it returns all users up to 200 as USER XXX, even though I only have 4 users loaded.
