RxA
The RXA (Receive—Radio A) connector is a N-type coaxial connector.
It connects to the
RX port on the rear panel of Radio A via a short coaxial
cable.
RxB
Same as
RXA, but for Radio B.
Antenna
The
ANTENNA connector is a N-type coaxial connector. It serves as the
connection point for the station antenna.
TxA
The
TXA (transmit, radio A) connector is a N-type coaxial connector. It
connects to the
TX port on the rear panel of Radio A via a short coaxial
cable.
TxB
Same as
TXA, but for Radio B.
Protected (Data)
This pair of connectors accepts data signals from each of the LEDR
radios. The top connector is for Radio A, and the bottom connector is for
Radio B. For pinout information, please consult the factory. Replace-
ment cables are available from MDS (P/N 03-3837A02).
E1
This is a block of four RJ-45 modular connectors for connection to a
multiplexer or other customer-supplied E1 equipment. For detailed pin
information, Figure 34 on Page 128.
These connectors are not operational on “S” Series (Subrate) radios.
Ethernet
The
ETHERNET connector provides access to the embedded SNMP
agent and other elements of the TCP/IP network management system.
The connector is a standard 10 Base-T connection with an RJ-45 mod-
ular connector. For detailed pin information, see Figure 34 on Page 128.
530 (A&B)
This pair of DB-25 connectors accepts EIA-530 data signals from each
of the LEDR radios. The top connector is for Radio A, and the bottom
connector is for Radio B. For pinout information, see Figure 36 on
Page 128.
