Multiswitches -4 Output LNB POWERED BY THE SATELLITE RECEIVER

6244 IFD Satellite IF Multlswltch with Passive VHF/UHF - LNB Powered by Sat. Receiver DISCONTINUED

6344 IFD Satellite IF Multiswltch with Active VHF/UHF - LNB Powered by Sat. Receiver

Multiswitch models 6244 IFD and 6344 IFD are identical to Models 6214 IFD and 6314 IFD except that they supply LNB power from the satellite receiver and do NOT require an 8014 IFD power supply They are intended for use in very small systems when 117 VAC is not available at the distribution point where it is desired to locate a multiswitch making these units ideal.

Model 6244 IFD has passive VHF/UHF processing allowing the system designer flexibility in the use of an external VHF/UHF amplifier. Refer to Model 6214 IFD for recommended VHF/UHF amplifiers. Model 6344 IFD includes a VHF/UHF amplifier. As such, at least one satellite receiver must be connected to Model 6344 IFD to pass VHF/UHF signals. Use Model 6244 IFD when VHF/UHF signals are not required.

Caution 1: Great care must be exercised when using these units to ensure that the satellite receiver will not be overloaded. The maximum current drawn from the satellite receiver will be 90 mA (for Model 6244 IFD) or 150 mA (for Model 6344 IFD)

PLUS LNB current (typically 200 mA) PLUS any line amplifiers.

This limitation may preclude the use of line amplifiers and/or Model 6334 IFD. Check with the receiver manufacturer.

Caution 2: Solid copper center conductor RG6U coaxial cable must be used. It has a loop resistance of 1.0 ohms per 100 feet. At 300 mA, this implies a voltage drop of 0.3 V per 100,. (Never use copper clad steel center conductor cable which has a much higher loop resistance.) As a result, to minimize voltage drops: (a) keep downleads from the multiswitch to the satellite receiver shorter than 75'. This will ensure proper switching action, and (b) keep cable lengths from the LNB to the multiswitch less than 75'. This will ensure adequate voltage to the LNB.

Caution 3: Note that the LNB voltages from the multiswitch are determined as follows:

Nominal 17V Highest satellite receiver voltage minus 0.3V.

Nominal 13V=11.2V (with greater than 12.0 V into any output).

Check that these voltages are compatible with the LNB in use.

Fig. 1 shows a four output system using these units.
