The Extended I/O Mode - Zektor HDA604 User Manual

The Extended I/O mode

This manual assumes all Zektor switches have been set to the Extended I/O mode.
This mode sets all of our switches to use the same source numbering. This allows writing a single
driver that can be used with multiple switches.
In the Extended I/O mode, all switches use the same mappings for the sources. Setting a zone to a
source that doesn't exist, (like setting a zone to analog input 17, on a switch with only 16 analog
inputs) will simply mute the zone -- it's the same as setting the zone to 0.
To use the Extended I/O sources you have set the XIO flag in the 'XS' command to one (1) by sending
the following commands:
^XS +32768$
^SS 8$
The 'SS' command will save the settings in EEPROM so that the Extended I/O setting is saved
through a power cycle. Otherwise you will need to send the 'XS' command each time you initialize the
switch after applying power. (See: "'XS' Control Settings" on page 52, and "'SS' Save Default
Power On Settings" on page 55.)
In the Extended I/O mode, the sources for the analog audio zones are (see "'SZ' Set Zone(s) -- Analog
Audio Switch" on page 41):
0
1-32
33-64
65-80
81-96
97-112
113-128
Note: Only SPDIF type audio can be extracted from the HDMI video. Only PCM-stereo type audio can
be down-converted to analog audio. You cannot down-convert Dolby5.1 or DTS. You cannot extract,
or down-convert high definition audio like Dolby TrueHD or DTS Master Audio.
The sources for the digital audio zones are (see "'DSZ' Set Zone(s) -- Digital Audio Switch" on
page 45):
0
1-32
33-64
65-80
81-96
97-112
113-128
129-144
Note: Only SPDIF type audio can be extracted from the HDMI video. Only PCM-stereo type audio can
be down-converted to analog audio. You cannot down-convert Dolby5.1 or DTS. You cannot extract,
or down-convert high definition audio like Dolby TrueHD or DTS Master Audio.
