2.1 Installation Overview
In order to set up your camera, you should take these initial steps:
1. Power down all equipment.
2. Following the manufacturer’s instructions, install the frame grabber (if applicable). Be sure to
observe all static precautions.
3. Install any necessary imaging software.
4. Before connecting power to the camera, test all power supplies. Ensure that all the correct voltages
are present at the camera end of the power cable (Refer to the Camera Performance Specifications
on page 7). Power supplies must meet the requirements defined in section 2.4 Power Input.
5. Inspect all cables and connectors prior to installation. Do not use damaged cables or
connectors or the camera may be damaged.
6. Connect data, serial interface, and power cables.
7. After connecting cables, apply power to the camera. The POST (power on self test) LED on
the back of the camera should glow green after one second to indicate that the camera is
operating and ready to receive commands.
2.2 Input/Output
The camera provides 12-bit LVDS data and synchronization signals through the data output
connector. Camera functions such as integration time, camera gain and offset are all controllable
by the user via the RS232 serial port. The camera is capable of free running operation or may be
triggered externally via the input TRIGGER IN. TRIGGER OUT allows the synchronization of
shutters or illumination sources in free running or externally triggered modes.

Note: Performance specifications are not
guaranteed if your power supply does not
meet these requirements.
DALSA offers a linear power supply (with
cables) that meets the 4M30’s requirements
(Universal Power Supply, part number 24-
00001-02, contact DALSA for more
information), but it should not be considered
the only choice. Many high quality supplies
are available from other vendors. DALSA
assumes no responsibility for the use of these
supplies.
When setting up the camera’s power supplies, follow these guidelines:
•Do not connect or disconnect cable while power is on.
•Do not use the shield on a multi-conductor cable for ground.
•Keep leads as short as possible to reduce voltage drop.
•Use high-quality linear supplies to minimize noise.

2.6 Serial Communication
Connector and Pinout
The serial interface provides control of frame rate, integration time (shuttering), video gain and
offset, external trigger and external integration. For information on how to control these functions,
see Camera Operation, beginning on page 19. The remote interface consists of a two-wire (plus
ground) full duplex RS-232 compatible serial link, used for camera configuration, and two back
panel SMA coax connectors used for external trigger input and output.

RJ-11
View into female jack
6-position with 4 conductors
RXDTXDGND
The camera uses an RJ-11 telephone-style connector for serial
communications, with four conductors installed in a six-position
connector. Note that both four- and six- conductor plugs may be
used interchangeably with the RJ-11 jack.
IMPORTANT:Both the PC/AT and the camera are configured as
“DTE” (Data Terminal Equipment) devices requiring the TXD
and RXD lines to be swapped when interconnecting the two (note
that pin 4, normally the yellow wire, is not used on the RJ-11.)
That is, the TXD pin represents DATA OUT and the RXD pin
represents DATA IN on both devices, so that one device’s TXD
line must connect to the other device’s RXD line and vice-versa.

Serial Communication Settings
Table 9: Serial Port Configuration
Serial Port Configuration
Baud 9600, fixed
Start bits 1
Data bits 8
Stop bits 1
Parity None
The serial interface operates at RS-232 levels with fixed parameters of 9600 baud, 1 start bit, 8
data bits, 1 stop bit, and no parity. The interface uses only three wires, for received data,
transmitted data, and ground. In general writing data must start with a write command byte and be
followed by a data byte. Reading a camera register requires only a single read command byte.
WARNING: Due to initialization sequencing after power-up, no commands should be sent to the
camera for a minimum of 1 second after power up.
Serial Cable Source
The remote interface connector, on the cameras
rear panel, is specified as a low-profile RJ-11
modular connector. The connector is a 6-position
model, but only the center four positions are
populated with contacts. It will mate with either
the 4-position or 6-position cable plugs. This type
of connector typically requires special assembly
tools; complete cable assemblies are available
from suppliers such as Digi-Key:

DALSA provides serial cables in 3 lengths: 10’, 20’ and 50’. Part number CL-31-00004-xx
(where xx refers to the cable length in feet).
2.7 TTL Trigger Input and Output
Connector
The camera uses an SMA connector (labeled TRIGGER IN) to allow the user to provide a standard
TTL signal to control camera integration and readout. The input is high impedance (>10.5K),
allowing the user to terminate at the SMA input as needed. The camera has another SMA
connector (TRIGGER OUT) that provides a standard TTL output which is high whenever the
camera is integrating.

2.8 Integration Time
The minimum integration time (or shutter time) is 10 µs. As with any full frame imager, the camera
will continue to integrate during read out unless externally shuttered or strobed.
2.9 Timing
The 4M30 pixel clock runs at 40 MHz, so each pixel clock cycle will be 1/40,000,000 or 25ns. The

3.1 How to Control the Camera
The 4M30’s RS-232-compatible serial interface allows you to control its configuration and
operation, including:
• Triggering Mode
•FrameRate
• Integration Time
•Gain
• Offset
• Reset
Command Protocol Overview
The camera accepts 8-bit command/value pairs via its
RJ-11 serial port using RS-232 compatible signals.
Camera commands are divided into two basic sets:
• “clock” commands which apply to the electronics
that drive the image sensor. These include clock
generation, frame rate, integration time, and
binning. Clock commands effect the entire
camera, and are not channel specific. A single
command will impact all channels.
• “ADC” commands which apply to the electronics that process and digitize the video. These
include gain and offset. ADC commands are channel specific. Four separate commands must
be issued to change all four channels.
