3.11 PTZ Control / Alarm Outpu
t
For space considerations, the alarm output and PTZ control output share the same Female DB9 port on the rear panel. The IV-PTZAOC
cable is provided with your DVR for easy connection to your alarm system and PTZ cameras. Refer to the diagrams below for more
information about wiring. PTZ control is via RS485 TX+ and TX– only. Software includes code support for Pelco, Panasonic, Kalatel and
Sensormatic PTZ brands. The watchdog output follows a fault condition and closes only when the DVR loses power or when the cap-
ture cards stop communicating with the CPU. The incident output is a momentary (about 1 second) output triggered by the software’s
Alarm Output feature. Watchdog and incident relays are designed to handle a maximum of 30 V
DC
and 1 Ampere.
Warning: Exceeding these ratings will damage the DVR and void the warranty.
3.12 External
Inputs
Your DVR is equipped to handle up to 16 external dry contact inputs connected to the DB25 External Input port on the same
expansion slot as the PTZ/Alarm Output port. External Inputs allow connection of dry contacts from devices such as remote motion
detectors, door switches, etc. Pins 1 through 16 correspond directly to inputs 1 through 16. Pins 17 through 25 are internally
connected to a common ground. Please refer to software documentation for instructions to confi gure inputs for “normally open” and
“normally closed” signaling devices. No break-out cable is provided for your External Inputs.
