@
zone
= One (or more) zones to be mapped.
in
= Source to map to given zone(s).
ch
= Channel bitmap.
‘HSZ’ Examples
The ‘HSZ’ command in its simplest form:
^HSZ @1,@3,2$
maps the input ‘2’ to the zones ‘1’ and ‘3’. You can also map multiple zones and inputs using a single
command. For instance:
^HSZ @1,2,@3,@5,7$
maps the input ‘2’ to zone ‘1’, and also maps the input ‘7’ to zones ‘3’ and ‘5’.
By appending a ‘.’ and a channel bitmap to the ‘SZ’ command, the command can also be used to
breakaway the different channels:
^HSZ.8 @1,3
maps only the HDMI audio from input ‘3’ to zone ‘1’. The HDMI video on zone 1, remains
unchanged.
The channel (the ‘.8’ in the above example) is a bitmapped number that indicates which channel or
channels are to be affected by the command.
The channels are mapped as:
1 = HDMI video
8 = HDMI audio
By adding together the above numbers, you can switch any combination of channels without affecting
the unselected channels.
For instance:
^HSZ.1 @3,4$
would map only the HDMI video from input ‘4’ to zone ‘3’.
To map both the video and audio channels, add the HDMI video and HDMI audio channel numbers
together: 9 = 8 + 1, and use that as the channel number:
^HSZ.9 @2,@3,4$
This would map the HDMI video and HDMI audio channels from input ‘4’ to zones ‘2’ and ‘3’.
There are two forms of the query response string, depending upon whether any channel breakaway
options are in affect.
If HDMI video and HDMI audio, from input ‘3’ are all mapped to zone ‘1’, then:
^HSZ @1,?$
->
Query request sent to the A/V switch
would respond with:
^+$
<-
Indicates no errors in the command
^=HSZ @001,003
<-
Video and audio channels are all mapped to input 3
If instead, zone ‘1’ had HDMI video from input ‘3’ mapped to it, but had digital and HDMI audio from
input ‘4’ mapped to it, the response would have been:
^=HSZ.1 @001,003
<-
HDMI from input ‘3’ mapped to zone 1
^=HSZ.9 @001,004
<-
HDMI S/PDIF audio from input ‘4’ mapped to zone ‘1’
