PORT USE Types
ALARM - Used for an Alarm Interface Unit connection for input of alarm codes to the 1996R CPU. Each alarm event message
sent to this port generates an output message to a serial printer via the PRINTER port (see below).
KEYBOARD - Enables keyboard (or computer) control inputs to the port. For this use set Data Bits to 8, Parity to NONE, and
Stop Bits to 1. When a Port Expander is used, the port baud rate must be set to 4800, and the keyboards set to 1200.
TERMINAL - Used to upload and download setup information for the 1996R CPU from a PC. Select the Terminal option when
using the 1996R SW13 software package. To obtain consistent performance from a PC, a 4800 baud rate is recommended.
PRINTER - Outputs messages of all Alarm and Video Loss events, both occurrence and removal, to a serial printer.
The ALARM event message format is as follows:
05-MAR-1993 13:23:26 CONTACT 0001 CAMERA 0001 MONITOR 0001 CONTACT OPENED
Date of Event
Contact Number
Monitor Number
Alarm Status
that caused Alarm
armed for that contact
Time of Event
Camera Number associated with that contact
Alarm Status:
CONTACT OPENED - indicates the alarm contact has been cleared
TIMED OUT - indicates the alarm was removed by timeout (Auto Clear)
ACKNOWLEDGED - indicates the alarm was removed by operator Acknowledge
When an alarm first occurs, Alarm Status is blank.
The VIDEO LOSS message format is as follows:
05-MAR-1993 13:23:26 CAM 0001 VIDEO YES SYNC YES
SET LOW
Date of Event
Camera Number Video Loss
Video Loss Detection Mode
that lost video
Time of Event
Sync Loss
Video Loss:
VIDEO YES - indicates that the video signal is present
VIDEO NO - indicates that there is no video signal
VIDEO LOST - indicates that the video signal was just lost
VIDEO RESTORED - indicates that the video signal was just restored
Sync Loss:
SYNC YES - indicates that the sync signal is present
SYNC NO - indicates that there is no sync signal
SYNC LOST - indicates that the sync signal was just lost
SYNC RESTORED - indicates that the sync signal was just restored
Video Loss Detection Mode:
SET OFF - video loss detection is currently disabled
SET LOW - sync and low picture content video loss detection enabled
SET MEDIUM - sync and medium picture content video loss detection enabled
SET HIGH - sync and high picture content video loss detection enabled
SET SYNC ONLY - sync loss detection only enabled
In addition, the following message is printed when the VLD module is cleared, by the “108 F2” command (see page 3-3):
05-MAR-1993 13:23:26 REAL CAMERA INPUTS nnnn TO nnnn DISABLED
(Where the nnnn TO nnnn indicates the group of cameras that were cleared.)
VIDEO LOSS - Enables communication with a Video Loss Detector module via the port. Each video loss message sent to this
port from the VLD module generates an output message via the PRINTER port (see above).
