DRAFT
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 A620
f
is 2.3 W at 12 VDC. Ripple must be less than 1%.
2.4 IEEE 1394 Device Information
The A620f uses 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.
