When an external synchronizing signal input is provided to the external synchronization input
connector on the rear side of the camera for loop through, select "Hi-Z". To terminate the con-
nector, select "G/L 75 Ω". Select "G/L 75 Ω" for the normal situation, too.

Important:
• Be sure to turn off the power of each device before connection.
Alarm output
Output specification:Open collector output
(max. voltage: 16 V DC)
Off:2 to 4 V DC, internally pulled up
On:Output voltage 1 V DC or less (max. drive
current: 100 mA)
Color/black-and-white input
Input specification:No-voltage make contact
input (3 to 5 V DC, internally pulled up)
Color:Open or 3 to 5 V DC
Black and white:Make contact with GND
(required drive current: 0.2 mA or more)
* When color input or black-and-white input is
enabled, set the black-and-white switching, "BW MODE" to "EXT". (☞page 40)
* When an external device is connected, exercise care to avoid exceeding the rating.
* Applicable wire: AWG22-AWG28, solid wire/stranded wire
Strip the end 9 to 10 mm {30" to 33"}of the wire and insert it.
