DB25 Electrical Specification:
The +5V output on the connector is protected internally by a 200mA self-resetting
fuse. If LED drive outputs are used, it is recommended that s5V connections
be used to drive the anodes of the LED’s (at least one +5V wire per LED used). The
active-low LED drive outputs are current limited by internal 110 ohm series resistors,
and are capable of sinking 20mA each. The active-high switch inputs are TTL-level
inputs with 100K pull-down resistors.
Typical Usage:
Currently, the software supports remote talkback switching and status on Switch
inputs 1-4 and LED outputs 1-4
on the CM401 Expansion Port only
. Functionality is
as follows:

For example, while Switch 1 is pressed down, the Talkback mic signal will be
routed to the Mon A output, and LED 1 will light during the time that the switch is
pressed down. Also, if Talkback
!
Mon A is activated from the console itself, LED 1
will also light, to indicate the status.
Pressing SW1A routes the Talkback signal to Mon A, and the SW1B LED lights to
indicate the Talkback
!
Mon A status.
