Slave Unit(s) Set-up
All slave units are cabled the same way using coax RG6 or RG11 for back bone. The following section
describes the CASCADE features of the Distribution ZHC.
CASCADE TOPOLOGY
1. The Master unit produces a 35 dBmV, 1kHz tone at 870 MHz and injects it into the RF stream
coming from the Outbound Coax. The connected downstream unit detects the tone from the
Master, which sets the unit to Slave. The slave unit then measures the tone and automatically
adjusts its internal attenuators and slopers to produce the proper RF output levels for the unit.
2. Cascades can go 4 levels deep, Master to 3 Levels of Slave cascade
3. All cascades go from an OUTBOUND COAX port (MASTER or Lower Level Slave) to the
CATV/CAS IN Port (Higher Level Slave)
4. T
he distance between units can be up to 400’ when using RG6 cable and 600’ when using
RG11 cable.
5. Always try and design to keep the lowest level Cascade. Example: Closet has the
MASTER and 3 SLAVE units. The proper way to Cascade is to take 3 feeds from the
Outbound Coax on the MASTER and Run one to each of the Slaves. The wrong way is
to go from the Master to Level 1 Slave, from Level 1 Slave to Level 2 Slave, from Level 2
Slave to Level 3 Slave.
