External Interfaces
AUDIO/INTERCOM (25-pin D-sub, female)
a) Analog audio interface
Input: +4dBu/0dBu/
−
20dBu
Output: +4dBu/0dBu/
−
20dBu
TALLY/GPIO (25-pin D-sub, female)
a) Tally interface
Input
ON: TTL;H, Contact; Short
OFF: TTL;L, Contact; Open
Output
ON: Contact; Short
OFF: Contact; Open
b) GPIO interface
Input: L;0, H;+5V
Output: L;0, H;+5V
When used as an input, an external pull-up resistance of
approximately 10 k
Ω
is required because the unit has an
internal 100 k
Ω
pull-down resistance.
When used as an output, the load should be configured
such that the current does not exceed ±5 mA.
