Alarm/Remote Terminal Setting
The rear of the unit is provided with an 11-pin terminal, ALARM/REMOTE.
Pins from #1 to #5 perform as follows.
Pin #1 supplies an active output for the duration specified by the ALARM OUTPUT in the setup.
The output type is a low-active open collector with a capacity of 16 V DC, 100 mA maximum.
Pin #2 accepts an alarm reset pulse (input) that makes the unit reset the alarm mode.
A no-voltage make-contact is accepted.
Pin #3 supplies an alarm reset pulse (output) when the unit resets the alarm mode.
The output type is 0 V (active)/5 V for the default setting, or a low-active open collector with controllable capacity of 16 V
DC, 100 mA maximum after changing an internal switch (SW 704).
Pin #4 accepts a spot switching pulse (input) from other units in a multi-unit connection.
A no-voltage make-contact is accepted.
Pin #5 supplies a spot switching pulse (output) to other units when the unit selects a new camera channel in a multi-unit
connection.
The output type is a low-active open collector with a capacity of 16 V DC, 100 mA maximum.
Pins #6 to #9 are used in many ways depending on the menu settings and the internal connector settings. If internal adjust-
ments are required, please refer to the Service Manual available for this unit.
