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 several +5V 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:
Function Triggered by Status shown on
Talkback à Mon A Switch 1 input
(momentary)
LED 1 output
Talkback à Mon B Switch 2 input
(momentary)
LED 2 output
Talkback à Mon C Switch 3 input
(momentary)
LED 3 output
Talkback à Mon D Switch 4 input
(momentary)
LED 4 output
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 à 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 TalkbackàMon A status.
