Strata RX
Technical Reference Manual
When an RXU and an RCU are connected, you need to connect
to only one of their RS-232 connectors. The RXU and RCU will
communicate over the coaxial connection between them, and
the Configurator commands will be automatically routed to the
correct unit.
The RX is configured to be a DTE device. If you need to access
only the Radio Programming and Monitoring connections, a null
modem cable can be used to connect the RX to your PC. One
cable is supplied with each RX ordered. Additional cables can be
purchased from Vislink (part number 56500-108) or at any
computer or electronics store.
Radio Programming and Monitoring connections are shown in
Table 6-5 and Figure 6-12.
6.10.3 Wayside Data
This connection is used for carrying Wayside Data from the RX
to an external device.
The RX System supports an embedded 9.6 kb/sec Wayside
Data channel. This channel is available when an MPEG decoder
is installed and the radio is in Digital Mode. Data rates are from
1200 baud to 38,400 baud.
Note
that the Wayside Data is only present on the RS-232
connector on the unit in which the MPEG decoder is
physically
located
.
Wayside Data connections are shown in Table 6-5 and Figure 6-
12.
6.10.4 Panel Data Connectors
The pinout of the panel DB-9 connectors is shown in Figure 6-9
and Table 6-5, and illustrated in Figure 6-12.
