Page 4: Returns
Returns This item was thoroughly tested and carefully packed at the factory prior to shipping. Upon acceptance by the carrier, the carrier assumes responsibility for the item’s safe arrival. Should you receive the item in a damaged condition, apparent or concealed, a claim for damage must be made to the carrier. If a visual inspection shows damage upon receipt of this shipment, it must be noted on the freight bill or express receipt and the notation signed by the carrier’s agent. Failure to do this can result in the carrier refusing to honor the claim. When the damage is not apparent until the unit is unpacked, a claim for concealed damage must be made. Make a mail or phone request to the carrier for inspection immediately upon discovery of the concealed damage. -

Safety instructions WARNING: Power supplies used with these Cameras operate from 115 V AC or 24 V AC. These voltages are dangerous. Use extreme care working with equipment connected to either 115 V AC or 24 V AC. CAUTION: In order to avoid deterioration of the color filter of the CCD and potential discoloration of the image avoid pointing the Camera directly toward the sun or other bright source. WARNING: Do not remove camera from housing. There are no user serviceable parts inside. •... -

Page 9: System Cable Requirements
2.1 System Cable Requirements To build the Camera system cable CohuHD recommends: • For Ethernet: CAT5e or better cable is recommended. For distances up to a maximum of 100 me- ters (328 feet), use CAT5e cable with four pairs of copper wire, 24 AWG. • For Analog Video: The coax for analog video should be rated at 75 ohms, and should not exceed a maximum attenuation of 6dB at 10MHz for the length of coax required. For example, Belden 9221 miniature coax is a small, extremely flexible, 75 ohm coax that has an attenuation of 2.2dB per 100 feet. It should never be used for distances longer than 270 feet ((6dB / 2.2dB) x 100ft. = 272 feet). An excellent mid range coax would be the Belden 8241F (RG-59/U type with 100% copper core), with an attenuation of 0.9dB per 100 feet, or a maximum recommended distance of 650 feet. For longer cable runs, the Belden 8238 (RG-11/U type) has an attenuation of 0.7dB per 100 feet, which would allow for a maximum cable length of over 850 feet. There are triaxial cables available that can accommodate even longer cable distances, but a video cable equalizer or fiber optics may prove to be more cost effective as a long distance solution. • For Data: Shielded, two twisted pair data cable is recommended. For lower baud rates (9,600 or less), the Belden 8723 shielded cable is usually suitable for distances up to 750 feet. For longer cable runs, and/or faster baud rates, a cable with a lower capacitance per foot should be selected. The Belden 8162 (12.5pf/ft. capacitance), would be suitable for distances well in excess of 1,000 feet at baud rates up to 115KB. -

In the 3920 /3920 series Cameras the RS-422 interface is used for sending and receiving serial data. Therefore, a RS-232/422 converter should be used between the Camera and a computer. Figure 3 shows a typical RS-232/422 converter from B&B that could be used with 3920 /3920 . Table 3 shows cable wiring between the Camera and a converter. B&B converter 422PP9TB... -

2.3 CohuHD Manufactured System Cables CohuHD manufactured cables are available for 3920 /3920 series Cameras operating from 115 V AC power or 24 V AC with MS connectors. See table 4. Cables are made with either stripped (prepared) leads or with various combinations of connectors and a RS-232/422 converter. “Stripped” in the tables indicates that the wire leads are stripped and pre-tinned with solder for attachment to a terminal strip or similar device. - Page 13 MS Connector RJ45 Ethernet Video Camera Side Control Side /DATA Alarm RS422 Data Overall Shield 24 V AC Note: NC = No Connection Figure 9.
