1. Connections and Connectors
The IC-360 makes use of two connectors on the top of the camera to make connections to
external devices. The following illustration and text detail the function of these connectors.
RS-232 Connector
Line Name Line Description
RS232 Receive (RXD)
This input conforms to normal RS232C specifications for a
“receive” line. At present, the IC-360 uses this connection
only to receive audio from the optional audio module.
RS232 Transmit (TXD)
This output conforms to normal RS232C specifications for a
“transmit” line. Baud rate and specific strings sent are
configured in the camera’s administration page. While
designed to control the optional audio module, this port can
be configured for many other purposes by the user.
Ground (GND)
Ground reference for Pins 1 and 2.

Line Description
External Sensor 1 + Input
This pin is connected through a 330 ohm series resistor to
(S1+) the anode of a Toshiba TPL504A or similar photo-coupler
input diode.
In combination with Pin 2, which is connected to the
cathode of the input diode, the signal here causes the Sensor
