Key to example system topologies (layouts) diagram
Feature Description
A
HMS-4X Main Station (digital main station) (rear panel).
There are two lines (digital partylines) on the main station, each of which can support up
to 10 digital HBP-2X beltpacks. There are two connectors (3-pin XLR, male and female)
for each line.
B
Daisy chained HBP-2X Beltpacks. To create a ‘daisy chain’ of connected beltpacks:
1. Connect the first beltpack to the main station, using either of the 3-pin XLR
connectors (female [ ] or male [ ] ) on the base of the beltpack.
2. Pass on the connection to the second beltpack, using the remaining connector
as the ‘pass thru’.
3. Repeat for all beltpacks (up to 10) in the chain. No cable termination is required.
C
The second layout uses an XLR Bulkhead and a Mult-box (passive (Y) splitters) to
combine:
• A daisy chain (with optional redundancy flyback).
• Point-to-point connected beltpacks (using the Mult-box).
The complexity and variety of layouts does not restrict physical access to channels.
Because HelixNet Partyline is a digital system, the HBP-2X Beltpacks can access any
two of the four available channels (plus a Program Feed), however they are connected
to the main station (see Figure 8: Analog and digital cabling comparison).
