TS4000 Radio Modem User’s Manual Radio Setup 24
Selection Description
Enable
Redundancy
This configures the TS4000s for use with the Redundancy
switch.
Redundant
Modem A
The TS4000 that is connected to the A side of the
redundancy switch must have this option checked.
Redundant
Modem B
The TS4000 that is connected to the B side of the
redundancy switch must have this option checked.
For redundant modems used in packet mode, the modems will consume
two individual packet addresses. The first address is the value configured on
the Packet for Port tab under Modem Address – Individual. The second is an
individual address 1 number higher. This is done automatically by the TS4000s
and the Individual Address must be configured the same for both redundant
modems. It is essential that the second address is not used by any other
modem in the network.
For additional information please reference the Redundancy Switch User’s
Manual.
Selection Description
Enable Sleep for
Low Voltage
With this enabled the modem will go into sleep mode when
the input power drops below the sleep voltage.
Sleep Voltage The voltage which puts the modem into sleep mode.
In sleep mode the status lights will be off with the exception
of the power light which will flash briefly every several
seconds.
Wake Up
Voltage
Once the modem is in sleep mode it will remain until the input
voltage rises above this voltage.
When the modem wakes up the Rx and Tx lights will flash
together three times.
Selection Description
Disabled This minimizes the amount of overhead required to send
data.
Enabled Transmit data is block coded (12,8 Hamming) and interleaved
(16 bits). This provides forward error correction (FEC) for
strings of errors up to 16 bits long. Coding requires an extra
50 % overhead on top of formatted data. This type of coding
is ideal for combating errors induced from multi-path fading
common in mobile environments.
The scramble code determines the pseudo-random sequence used to scramble
the transmitted data. This provides data privacy and also randomizes the data
for optimum signal detection. All TS4000s operating in the same network must
use the same scrambling code.
