2.3 Installation
Step 1.
Prepare a PC with Ethernet link to the network
Step 2.
Connect an Ethernet cable
Connect LAN port (RJ-45) of the IP camera to a network switch. For ICA-8500,
when this switch is a PoE device, you can ignore the next step.
For ICA-8500, If there has an IEEE 802.3af PoE switch in your network, you can
connect the IP camera's LAN cable to this PoE switch to obtain power. The power
adapter is unnecessary when the IP camera is powered by PoE switch.
Step 3.
Attach the power supply
The 7-pin terminal block includes 1 input port and
2 output ports.
Description
Digital Input: Only one set is designed in this
camera model. The internal device is also a
photo-coupled electrical relay, and the external
device can be simply an On/Off switch. Each
set of On/Off switch can be connected as one
trigger source.
Digital Output: Each digital output pin to COM
is a photo-coupled relay on Normal Open
status. External device can directly connect to
the terminals. However, the current that will go
through the 2 nodes must not exceed 130mA.
An external "Relay" can also be connected to
the terminals as an implementation. In this
case, current (or/and voltage) limitation is
specified by the external Relay.
