Pcs400R; Video Channel Assignments For Rf Output (Qam-B); Video Channel Assignments For Rf Output (Dvb-C) - LG PCS400R Servidor Pro:Centric Instalación Y Configuración

PCS400R

• Unpack the PCS400R Pro:Centric server unit and all accessories.
PCS400R Accessories: AC Power Cord and Adapter
• Select the location for mounting the PCS400R. Ensure adequate ventilation is available.
• Obtain the necessary attachment hardware to mount the PCS400R chassis in its targeted location.
• Plan and install the necessary cabling and network (Ethernet) and AC power access for the PCS400R. You
also will need the following to connect a PC directly to the PCS400R for system setup purposes: FTDI TTL-
USB cable (P/N TTL-232R-5V-AJ).
Video Channel Assignments for RF Output (QAM-B)
Each input program is limited to one-half or one-third of the output channel bitrates (Mbps), which in turn are
dependent on the modulation format. 256-QAM modulation supports up to 38.8 Mbps per channel, and 64-QAM
modulation supports up to 26.97 Mbps per channel.
• Create a channel assignment plan for the installation site, or modify an existing plan to incorporate the RF
output of the PCS400R. Ensure that up to eight contiguous CATV broadcast channels are allocated for the
PCS400R RF output. The PCS400R uses a 256-QAM or 64-QAM modulation format, thereby occupying
approximately 48 MHz of frequency spectrum.
The RF start channel is user-assigned during system setup (in the Admin Client), and the remaining channels
(up to seven) are then automatically assigned per EIA-542 STD CATV frequency allocation standards. For
example, if the RF start channel assignment is channel 2, the seven remaining channels will be 3, 4, 5, 6, 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 PCS400R is 135. Thus, to allocate all eight channels available
for PCS400R RF output, the RF start channel must be set no higher than 128.
• Find a location on the frequency spectrum that is free of existing noise.
Video Channel Assignments for RF Output (DVB-C)
Each input program is limited to one-half or one-third of the output channel bitrates (Mbps), which in turn are
dependent on the modulation format. 256-QAM modulation supports up to 37.27 Mbps (6 MHz bandwidth),
45.05 Mbps (7 MHz bandwidth) or 50.87 Mbps (8 MHz bandwidth) per channel, and 64-QAM modulation
supports up to 27.95 Mbps (6 MHz bandwidth), 33.79 Mbps (7 MHz bandwidth) or 38.15 Mbps (8 MHz
bandwidth) per channel.
• Create a channel assignment plan for the installation site, or modify an existing plan to incorporate the RF
output of the PCS400R. Ensure that up to eight contiguous CATV channel frequencies are allocated for the
PCS400R RF output. The PCS400R uses a 256-QAM or 64-QAM modulation format, thereby occupying
approximately 48 MHz, 56 MHz, or 64 MHz (depending on channel bandwidth) of frequency spectrum.
The RF start channel frequency is user-assigned, in KHz, during system setup (in the Admin Client), and
the remaining channel frequencies (up to seven) are then automatically assigned in accordance with the
specified bandwidth. For example, if the RF start channel frequency assignment is 57000 KHz with a 7 MHz
bandwidth, the seven remaining channel frequencies will be 64000 KHz, 71000 KHz, 78000 KHz, 85000
KHz, 92000 KHz, 99000 KHz, and 106000 KHz.
The highest available RF channel frequency for the PCS400R is 861000 KHz.
