Start up
A Gigabit Ethernet port (1000Base-T) on the receiving computer is necessary. First connect the
camera with the appropriate data cable to the computer. Then plug the 15-pin connector of the power
supply to the camera and switch on the power supply.
The camera is controlled over a serial data interface via Gigabit Ethernet.

Direct Camera Control Signals
A short survey of the CC signals is given below for users who already have some experience in using
Camera Link equipment and who plan to use the IRC-320 with their self-developed software. Some of
the CC signals can also be externally applied to the 15-pin D-SUB control jack, which is compatible to
other VDS cameras.
In case of the Gigabit Ethernet interface option the same camera control signals are used, but they are
controlled by the corresponding outputs of a Programmable Logic Controller accessed over the Pleora
iPORT SDK. Please refer to the Pleora iPORT PT1000-VB User’s Manual and the Pleora iPORT
SDK Documentation for more information.

Camera Control Commands
To configure the internal image processing a serial command interface is provided. By default this
command interface is internally routed to the Gigabit Ethernet port, but the RS232 signals at the 15
pin D-SUB jack may also be used. To access it, a serial terminal program employing the serial port of
the user’s Pleora iPORT software interface or a PC’s RS-232 COM port is required.
For Gigabit Ethernet the Pleora iPORT documentation contains the corresponding information. If the
serial interface is routed over the 15 pin D-SUB jack, then e.g. HyperTerminal, being part of
Microsoft® Windows® deliveries, might be the choice to manually control the camera.
The VDS provided software AcquireControl can operate the camera’s serial port over the Pleora
iPORT Gigabit Ethernet interface or PC standard COM ports. Type <CTRL>+Y to get a camera
control terminal window there.
By default the serial interface uses the following parameters:
•
115200 Baud
•
8 data bits
•
1 stop bit
•
No parity
•
No handshake
The baud rate is factory-adjusted to 115200 but can also be configured to other values (see chapter
10.7, p. 29).
Each command consists of a command letter, followed by an equality sign and a parameter value in
hexadecimal number representation. The command letter is case sensitive. Hexadecimal values are
always upper case and are 1 to 4 digits long. The command is activated by a carriage return ([CR],
ASCII character number 0x0D. Serial communication operates in echo mode by default. This means
that each character received by the module is echoed back to the sender. In all command examples the
characters send to the camera are represented in
Bold Courier Font
and the camera’s answer in
Plain Courier Font
