2.4 Operation
1. Connect RF cables to the 1584-116 (See Section 2.2).
2. IF DC VOLTAGE IS REQUIRED ON THE SPLITTER RF INPUT (J17) CENTER CONDUCTOR,
install 1/4”, 0.5 amp fast blo fuses in the FUSE F1 holder
3. Connect 100-240 ± 10% VAC, 47 - 63 Hz to AC A and AC B on the back panel and observe A and B
LEDs are lit on the front panel.*
4. Monitor DC voltage to the external LNB amplifier (Front panel Green ON LED should be lit if LNB fuse
is installed in the rear panel fuse holder) to insure proper voltage.
*NOTE: Model 1584-116S has a single non-redundant, switching power supply.
CAUTION! IF A FUSE IS INSTALLED IN THE FUSE F1 HOLDER, +22 VDC WILL APPEAR ON
THE SPLITTER INPUT CONNECTOR (J17) CENTER PIN.
NOTE: FOR OPTIMUM PERFORMANCE, THE SPLITTER PORTS SHOULD BE TERMINATED
WITH 75 OHM TYPE F TERMINATION WHEN NOT USED.
AC Fuse - The fuse is a 5mm, 2 amp slow blo and is inserted in the far slot in the drawer below the AC
input as shown in Figure 2.6. There is a spare fuse in the near slot. If a fuse continues to open, the power
supply is most likely defective. Note that each power supply module within the chassis also has a fuse
but failure of this fuse indicates the power supply may be defective.
