Setup Information
Check the following items before you begin the PCS500R installation and setup procedures.
Note
: Once the PCS500R hardware and software is installed and the initial setup completed, output parameters
are configured in the appropriate Pro:Centric Admin Client. Along with this document, it is recommended that you
have readily available a copy of either the
Pro:Centric Server Admin Client User Guide
(for the Java application)
or the
Pro:Centric Direct Admin Client User Guide
(for the HTML application), as applicable.
PCS500R
•
Unpack the PCS500R Pro:Centric server unit and all accessories.
PCS500R Accessories: AC Power Cord and Adapter
•
Select the location for mounting the PCS500R. Ensure adequate ventilation is available.
•
Obtain the necessary attachment hardware to mount the PCS500R chassis in its targeted location.
•
Plan and install the necessary cabling and network (Ethernet) and AC power access for the PCS500R. You also
will need the following to connect a PC directly to the PCS500R for system setup purposes: FTDI TTL-USB
cable (P/N TTL-232R-5V-AJ).
Video Channel Assignments for RF Output (QAM-B)
Each input programme 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 PCS500R. Ensure that up to eight contiguous CATV broadcast channels are allocated for the
PCS500R RF output. The PCS500R 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 or also
user-assigned, depending on channel selections in the Admin Client.
Note for contiguous channel allocation
: 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 PCS500R is 135. Thus, to allocate all eight channels available
for PCS500R 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.
