and to keep the housing temperature below 50° C. Additional cooling devices such as fans or heat
sinks are not normally required but should be provided if necessary.
1.6 Precautions
To ensure that your warranty remains in force:
Read the manual
Read the manual carefully before using the camera!
Keep foreign matter outside of the camera
Do not open the casing. Touching internal components may damage them.
Be careful not to allow liquid, flammable, or metallic material inside the camera housing. If
operated with any foreign matter inside, the camera may fail or cause a fire.
Electromagnetic Fields
Do not operate the camera in the vicinity of strong electromagnetic fields. Avoid electrostatic
charging.
Transporting
Transport the camera in its original packaging only. Do not discard the packaging.
Cleaning
Avoid cleaning the surface of the CMOS sensor if possible. If you must clean it, use a soft, lint free
cloth dampened with a small quantity of high quality window cleaner. Because electrostatic
discharge can damage the CMOS sensor, you must use a cloth that will not generate static during
cleaning (cotton is a good choice).
To clean the surface of the camera housing, use a soft, dry cloth. To remove severe stains, use a
soft cloth dampened with a small quantity of neutral detergent, then wipe dry.
Do not use volatile solvents such as benzine and thinners; they can damage the surface finish.

2.1.3 Connector Types
The 6-pin connector on the camera is a standard IEEE-1394 socket.
The 10-pin connector on the camera is an RJ-45 jack.
LThe camera housing is connected to the cable shields and coupled to signal ground
through an RC network (see Figure 2-3 for more details).
Caution!
The plug that you insert into the camera’s RJ-45 jack must have 10 pins.
Inserting a smaller plug, such as one with 8 pins or 4 pins, can damage
the pins in the RJ-45 jack on the camera.

2.2 Cables
The maximum length specified in the IEEE 1394 standard for the cable used between the camera
and the adapter in your PC or between the camera and a 1394 hub is 4.5 meters. Shielded IEEE
1394 cables must be used.
Basler has successfully tested a 10 meter IEEE 1394 cable and we offer this cable for sale. Since
the 10 meter cable length is outside of the 1394 standard, we cannot guarantee that it will work
properly in all applications and environments. If you want to use the 10 meter cable, we suggest
that you order a cable and test it in your environment.
The maximum length of the I/O cable is at least 10 meters. The cable must be shielded and must
be constructed with twisted pair wire. Close proximity to strong magnetic fields should be avoided.
2.3 Camera Power
Power must be supplied to the camera via the IEEE 1394 cable. Nominal input voltage is
+12.0_VDC, however, the camera will operate properly on any input voltage from +8.0 VDC to
+36.0 VDC as specified in the IEEE 1394 standard. Maximum power consumption for the A620f
is 2.3 W at 12 VDC. Ripple must be less than 1%.
2.4 IEEE 1394 Device Information
The A620fuses an IEEE 1394a - 2000 compliant physical layer device to transmit pixel data.
Detailed spec sheets for devices of this type are available at the Texas Instruments web site
(www.ti.com).
Caution!
Use only standard IEEE 1394 connectors.
The polarity of the input power to the camera must be as shown in Table
2-1. Do not reverse the input power polarity. Reversing the polarity will
damage the camera.

2.5 Input and Output Ports
2.5.1 Input Ports
A620fcameras are equipped with four physical input ports designated as Input Port 0, Input
Port 1, Input Port 2, and Input Port 3. The input ports are accessed via the 10 pin RJ-45 jack on
the back of the camera. See Table 2-2 and Figure 2-2 for input port pin assignments and pin
numbering.
As shown in the schematic in Figure 2-3, each input port is opto-isolated. The nominal input
voltage for the LED in the opto-coupler is 5.0 VDC (± 1.0). The input current for the LED is 5 to 15
mA with 10 mA recommended.
For each input port, a current between 5 and 15 mA means a logical one. A current of less than
0.1 mA means a logical zero.
By default, Input Port 0 is assigned to receive an external trigger (ExTrig) signal that can be used
to control the start of exposure. For more information about the ExTrig signal and for information
on assigning the ExTrig signal to a different input port, see Section 3.3.5.
2.5.2 Output Ports
A620fcameras are equipped with four physical output ports designated as Output Port 0, Output
Port 1, Output Port 2, and Output Port 3. The output ports are accessed via the 10 pin RJ-45 jack
on the back of the camera. See Table 2-2 and Figure 2-2 for output port pin assignments and pin
numbering.
As shown in the schematic in Figure 2-3, each output port is opto-isolated. The minimum forward
voltage is 2 VDC, the maximum forward voltage is 48 VDC, the maximum reverse voltage is 6
VDC, and the maximum collector current is 100 mA.
A conducting transistor means a logical one and a non-conducting transistor means a logical zero.
By default, Output Port 0 is assigned to transmit an integration enabled (IntEn) signal that
indicates when exposure is taking place. For more information about the IntEn signal, see Section
3.5.
By default, Output Port 1 is assigned to transmit a trigger ready (TrigRdy) signal that goes high to
indicate the earliest point at which exposure start for the next frame can be triggered. For more
information about the TrigRdy signal, see Section 3.4.
The assignment of camera output signals to physical output ports can be changed by the user.
See Section 6.7.10 for more information about configuring output ports.
LAs stated above, the nominal input voltage for the LED on each input is +5 VDC. If
a 560 Ohm resistor is added to the positive line for an input, the input voltage can be
12 VDC. If a 1.2 or 1.5 kOhm resistor is added to the positive line for an input, the
input voltage can be 24 VDC.
LBy default, output ports 0, 1, and 2 are set to a low state after power on. Output port
3 is initially set to low but will go high approximately 100 to 300 ms after power on.
Output port 3 will remain high for approximately 750 ms and will then reset to low.
