Drake SCT4860 8PSK Sat-1024QAM Cable Transcoder - Manual (Page 6)

6 Installation and Mounting
Installation and Mounting
install the SCt4860 transcoders in the Rmt150 rack mounting frame. Slide each module into the tray so that the
"f" connector extends though the front panel hole, the LeD is properly aligned behind its front panel hole, and the
hook shaped projection on the bottom of the module engages the rear of the mounting tray. Secure the module
with the supplied standard 1/2 inch "f" connector mounting nut and nylon washer.
Similarly, mount the PS151 power supply in the Rmt150 tray, making sure that the LCD display and control
buttons line up with their corresponding holes in the front panel, and that the hook shaped projections on the rear
of the unit engage the rear of the mounting tray. Secure the unit in place, with the supplied Philips head black
screws, from the front panel. Connect each SCt4860 to the PS151 with the cable included with the SCt4860.
each SCt4860 can connect to any one of the ten sockets on the power supply. However, to minimize confusion, it
is suggested that the left most unit (as viewed from the front panel) be connected to power supply socket number
1, the second from the left to number 2, etc.
Connect the LNB signal from the LNB splitter to each SCt4860 module at the front panel connector. Connect
each SCt4860 Rf output "f" connector on the rear of the unit to the output combiner. the Drake model LBS2250
is a combination LNB L band multiswitch/amplified splitter in addition to a CAtV output combiner. it provides
these functions in only 1 Ru of rack space. Also, plug the cable from the front panel fan module into the fAN
PoWeR receptacle on the rear of the power supply. Plug the line cord from the PS151 into the AC power source.
SCt4860s can be mixed with SCt1860s, SCt2860s, or SCt3860s and one PS151.
When installing the Rmt150 tray of transcoders, it is not necessary to leave a vertical airspace between the
transcoder tray and other equipment unless that other equipment specifies that a space should be left open. the
air flow through the transcoders and power supply has been designed to allow immediate adjacent mounting of
multiple Rmt150 trays with SCt4860 transcoders and PS151 power supplies installed. of course, air spaces
may be left in between Rmt150s if desired.
