Important!: In LRS455A-C, LRS455A-CE, LRS455-T radio networks, only one Repeater is
allowed. Adding a Repeater to a network reduces the throughput by 50%. For example, over-the-
air throughput in a network running at 2-Level GFSK and with the Repeaters parameter disabled is
9600 bps. With the Repeaters parameter enabled, the over-the-air throughput drops to 4800 bps.
The LRS455A-C, LRS455A-CE, LRS455-T radios are narrowband radios and have a limited
channel size based on the license obtained from the regulating body. Therefore, the radios can
experience a dramatic impact in throughput if a Repeater is implemented in the network.
If large amounts of data are transferred and a Repeater is added to the network, the polling host /
RTU settings must be optimized to accommodate for
t
he l
ower t
hroughput. P
olling host / RTU
optimization settings include reducing block / packet sizes and increasing overall time-out
parameters.
