I How to Use the Terminals of the ALARM/CONTROL Connector These terminals are used for emergency recording, auto time adjustment (Auto Adjust Time), taking measures against power outages (Shutdown Time), and when installing a buzzer, a lamp, or similar alarm device. They are also used to synchronize with the sequential display changeover. The terminal pin array and connections are shown below. The con- !3 q nector used should be compatible with the pin configuration. Pin array The pin array is different from other disk recorders. Make sure that the connection is correct referring to the following. ALARM/CONTROL @5 !4 Pin No. q w e r t y u i o !0 !1 Signal Ch 8 alarm output Ch 9 alarm output Ch 10 alarm output Ch 11 alarm output Ch 12 alarm output Ch 13 alarm output Ch 14 alarm output Ch 15 alarm output Ch 16 alarm output NC Alarm reset input !2 Emergency recording input !3, !4 Earth (Grounding) Alarm output for available !5 disk space of device con- nected to copy port !6 HDD error output Operation Alarm signal output at an event occurrence Only for the WJ-HD316A (Not available for the WJ-HD309A) Remarks Open collector output 24 V max., 100 mA Canceling the alarm display Starting emergency recording signal input Non-voltage make contact input -100 mA, 5 V pull-up Generation of signal output for disk space alarm- Open collector output ing of DVD-RAM, DVD-R and CD-R 24 V max., 100 mA Signal output upon detection of an HDD error !7 Camera error output Signal output upon detection of a camera error !8 Error output Signal output upon detection of a unit error !9 End of outage process- Signal output upon completion of outage pro- ing cessing High (+12 V) @0 Time adjustment I/O The time of this unit is adjusted to the preset time according to the signal input. This signal output is then generated for the setting time of this unit. Time of all other units is adjusted to the setting time of this unit. 30 kΩ 5 V pull-up, -100 mA/make contact Sequence changeover is affected according to @1 Sequence changeover the signal input. Signal output is generated at the I/O time of sequence changeover. @2 Alarm suspension input The state of alarm suspension is assumed according to the signal input. @3 Outage detection I/O Start of outage processing according to the signal input. Non-voltage make contact input -100 mA, 5 V pull-up @4 External recording mode Changeover to the external recording mode changeover @5 +5 V output +5 V output 200 mA max. 86
