16RS485 Terminal [485 A / B]The recorder can control PTZ (Pan/Tilt/Zoom) cameras using RS485 half-duplex serial communicationssignals. Connect RX+/TX+ and RX-/ TX- of the control system to the A and B (respectively) of the recorder.See “Chapter 3 -- Configuration” and the PTZ camera’s manual for configuring the RS485 connection.Alarm Input / Output Terminal [ALARM IN] / [ALARM OUT]Note: To make connections on the Alarm Terminal Strip, press and hold the button and insert thewire in the hole below the button. After releasing the button, tug gently on the wire tomake certain it is connected. To disconnect a wire, press and hold the button above thewire and pull out the wire.The 4-Channel model has 4 Alarm Input Terminals [AI1] to [AI4].[AI1] to [AI8] or [AI4] (Alarm Input) : You can use external devices to signal the recorder to react to events.Mechanical or electrical switches can be wired to the [AI] (Alarm Input) and [GND] (Ground) terminals. Thethreshold voltage of electrical switches for [NC] (Normally Closed) is above 2.4 V and for [NO] (NormallyOpen) is below 0.3 V, and should be stable at least 0.5 seconds to be detected. The voltage range of alarminput is from 0 V to 5 V. See “Chapter 3 -- Configuration” for configuring alarm input.[GND] (Ground) : Connect the ground side of the Alarm input and/or alarm output to the GND terminal.Note: All the terminals marked GND are common.[NC]/[NO] (Relay Alarm Outputs) : The recorder can activate external devices such as buzzers or lights.Connect the device to the [COM] (Common) and [NC] (Normally Closed) or [COM] and [NO] (NormallyOpen) terminals. [NC]/[NO] is a relay output which sinks 1 A 30 Vpeak (maximum). See “Chapter 3 --Configuration” for configuring alarm output.[ARI] (Alarm Reset In) : An external signal to the Alarm Reset In can be used to reset both the Alarm Outsignal and the recorder’s internal buzzer. Mechanical or electrical switches can be wired to the [ARI] (AlarmReset In) and [GND] (Ground) terminals. The threshold voltage is below 0.3 V and should be stable at least0.5 seconds to be detected. Connect the wires to the [ARI] (Alarm Reset In) and [GND] (Ground) terminals.Network Port [10/100BASE-T]The recorder can be networked using the 10/100Mbps Ethernet connector. Connect a Cat5 cable with anRJ-45 jack to the recorder connector. The recorder can be networked with a computer for remote monitoring,searching. See “Chapter 3 -- Configuration” for configuring the Ethernet connections.Important: The network port is not designed to be connected directly with cable or wireintended for outdoor use.Please keep away a cat5 cable and other cable which has a lot of noises,lightning and surge.Serial Port [SERIAL]Reserved.Audio Input / Output Connector [AUDIO IN 1 to 4] / [AUDIO OUT] (RCA pin jack)Your recorder can record audio from up to four sources. Connect the audio sources to the Audio InputConnectors 1 to 4 as needed using RCA jacks.Connect the Audio Output Connector to your amplifier.Note: It is the user’s responsibility to determine if local laws and regulations permit recordingaudio.The recorder does not have amplified audio output, so you will need a speaker with anamplifier. The recorder does not have a pre-amplifier for audio input, so the audio inputshould be from an amplified source, not directly from a microphone.
