Operating Modes; Master; Repeater; Remote - Microhard Systems Nano IP Series Operating Manual

4.0 Operating Modes

An Nano IP Series may be configured for any operating mode: this is very convenient for pur-
poses of sparing and becoming familiar with their configuration menus.

4.1 Master

One per network, the source of synchronization for the system. The Master controls the flow of
data through the system.

4.2 Repeater

Required only if necessary to establish a radio path between a Master and Remote(s); stores
and forwards the data sent to it. Synchronizes to Master and provides synchronization to
‗downstream' units.
If a local device is attached to a Repeater's serial data port, the Repeater will also behave as a
Remote (aka Repeater/Remote).
As they are added to a radio network it is good practice to use the values 2-17, sequentially, for
Repeater Unit Addresses.
Adding one or more Repeaters within a network will HALVE the throughput; the throughput is
halved only once, i.e. it does not decrease with the addition of more Repeaters.
If there is a ‗radio (signal) path' requirement to provide Repeater functionality, but throughput is
critical, the repeating function may be accomplished by placing two Nano IP Series at the Re-
peater site in a ‗back-to-back' configuration. One Nano IP Series would be configured as a Re-
mote in the ‗upstream' network; the other a Master in the ‗downstream' network. Local connec-
tion between the modems would be accomplished with a crossover cable (for the ethernet con-
nection). Each modem would require its own antenna; careful consideration should be given
with respect to antenna placement and Nano IP Series configuration.

4.3 Remote

Endpoint/node within a network to which a local device is attached. Communicates with Master
either directly or through one or more Repeaters. See Sections 5.3 and 5.4 for information re-
Throughout this
garding ‗Slave-to-Slave' communications.
manual, 'Remote'
refers to a Remote as
defined in Section 4.4;
the general term
'remote' applies to an
IP Series Repeater
and/or Remote - i.e.
non-Master unit.
