[Alarm Output Terminal] (Pin No. 1 – 16)

The terminal of the number corresponding to the alarm-activated camera number shorts with the ground terminal. Alarm output terminals 1 – 16 are the NPN open collector output.

Operating current: Maximum 20 V, 20 mA

[Alarm Output Terminal] (Pin No. 22)

This terminal is shorted with the ground terminal even when only one of the alarm input terminals receives an alarm signal. The alarm output terminal is the NPN open collector output.

Operating current: Maximum 20 V, 20 mA

[Alarm Input Terminal] (Pin No. 23)

Shorting this terminal with the ground terminal when "OTHER16," "OTHER16-64" or "OTHER" has been selected in the "SWITCHER" setting will sound a buzzer and cause the Alarm Reset indicator to flash while it is shorted. (Refer to p. 25 "Switchers.")

Open voltage: 5 V DC, short-circuit current: Maximum 5 mA

[Home Position Selection Input Terminal] (Pin No. 24)

When Auto-Return is performed while this terminal is being shorted to the ground terminal, the camera's operation follows the setting made for "2" in the "Home position" setting. (Refer to p. 28 "Home position.")

Open voltage: 5 V DC, short-circuit current: Maximum 5 mA

[Auxiliary Input] (Pin No. 25) Leave this input unconnected.

Open voltage: 5 V DC, short-circuit current: Maximum 5 mA
