RS-485 Repeater

As stated in the previous section, RS-485 Guidelines, a
NetClock or TimeBridge can drive up to 32 devices over
a maximum cable length of 4000 feet. The guidelines
also recommend the RS-485 transmission line be con-
nected in a continuous daisy-chain configuration. A
branched or star configuration is not recommended, as
well as long stub lengths to the main transmission line.
If these guidelines present an installation problem, the
RS-485 Repeater output can be used. The Repeater
output regenerates the synchronizing data stream ap-
plied to the RS-485 Input/Output terminal block connec-
tions. The Repeater output can drive an additional 32
devices over cable lengths up to 4000 feet.

The Repeater output may be used to reduce and simplify
cable runs to devices located in different portions of the
building. Figure 2-8 shows an installation where the
backup dispatch consoles located in the basement re-
quires synchronized time.
