    Alarm tone is added just before the speaker output. When select switches are used a soft mute is applied to the audio to reduce glitches. AEQ AM-04 Analog, AES/EBU and SDI embedded Audio Monitor with Alarm System...

  • Page 7: Operation

    Note: To prevent de-muxed audio from being corrupted or muted, ensure that the 525/625 switch at the rear of the unit is correct for the SDI source. 3.2. USING ALARMS The AM-04 can provide the following warnings: Alarm event Notes...
  • Page 8 Note: Restoring input signals to normal condition does not clear alarms. Arming phase alarms Only the phase LED on the AM-04 front panel is armed using the SET switch. The audio tone and external phase alarms can only be armed using serial control.

  • Page 22: Remote Control Protocol

    6. REMOTE CONTROL PROTOCOL The AM-04 is automatically placed in the remote mode upon receipt of a valid RS232 command. The front panel can be reactivated by powering off and on or by sending it a disconnect command. Commands to be communicated to the remote unit (AM-04) are arranged in frames. These frames will then be sent to the remote unit, which will always reply with either ACK for acceptance or NAK for rejection.
  • Page 23 Replies, when requested (e.g. 82), will consist of frames that contain the original command value plus 0X40. So a request for an ident, 0x82, will elicit a reply of a frame containing 0xC2 and the ident string. (AM - 04Vn.n) AEQ AM-04 Analog, AES/EBU and SDI embedded Audio Monitor with Alarm System...

  • Page 26 Phase Byte 1 Disable The Auto bit will cause the AM-04 to generate spontaneous ACK signals every second while an alarm is active. The toggle disable bit will inhibit the set-up function of the front panel toggle switch. Request Detail (0x85) This command will cause the AM-04 to respond with a frame containing the command 0XC5 and data describing the state of the unit and any alarms.
