Setup Information
Check the following items before you begin HCS6320 installation and setup procedures.
HCS6320
__ The HCS6320 feature card must be installed in a CodePlus™ HCS6150 card frame with
one or more CodePlus series HCS7720 transcoder cards. Refer to the Installation & Setup
Guide for the card frame to verify that the chassis is installed properly. Note: All cards
must be used in an LG-approved card frame for this product.
__ The HCS6320 must be installed in the card frame CONTROLLER slot. If another
CodePlus feature card is currently installed in the CONTROLLER slot, the HCS6320 will
replace it.
__ The HCS6320 ships with a spare HCS6400 fan card. In an HCS6150R card frame,
HCS6400 fan cards are pre-installed in Slots 3, 6, 7, and 10.
__ For HSC6320 Service Port connections, you must use an FTDI TTL-USB cable (P/N
TTL-232R-5V-AJ).
Channel Assignments
__ Create a channel assignment plan for the installation site, or modify an existing plan
to incorporate the RF output of the HCS6320. Ensure that up to four contiguous CATV
channels are allocated for the HCS6320 RF output. The HCS6320 uses a 256-QAM
modulation format, thereby occupying approximately 24 MHz of frequency spectrum.
The RF start channel is user-assigned during system setup, and the remaining channels
are then automatically assigned per EIA-542 STD CATV frequency allocation standards.
For example, if the RF start channel assignment is channel “2,” the three remaining
channels will be “3” “4” and “5.” However, if the RF start channel assignment is “6,” the
three remaining channels will be “95” “96” and “97.” Refer to EIA-542 STD CATV frequency
allocation tables for further information as required.
The highest available RF channel number for the HCS6320 is “135.” Thus, to allocate all
four channels available for HCS6320 RF output, the RF start channel must be set no
higher than “132.”
Transcoders
__ For HCS6320 MUX/MOD functionality, HCS7720 transcoder cards should be inserted in the
following slots: 1, 2, 4, 5, 8, 9, 11, and 12. Refer to the Installation & Setup Guide for
HCS7720 transcoders to verify that the cards are installed properly.
