Ethernet in
a Protected
Configuration
The Ethernet connections on the LEDR radio chassis in a protected con-
figuration should not be used. The Ethernet connector of the Protected
Switch Chassis (PSC) provides a connection to the two radio units. Each
radio has a unique IP address and is individually addressable/control-
lable using SNMP over IP. See “PROTECTED CONFIGURATION”
on Page 103 for general information and Figure 34 on Page 128 for
ETHERNET connector pinout details.
EIA-530-A
The EIA-530-A connector is the main data input/output connector for
the subrate radio. The EIA-530 interface is a high-speed serial data con-
nector. For detailed pin information, see “EIA-530-A Data—Rear
Panel” on Page 128.
NOTE: This connector is not operational on LEDR “F” Series (fullrate)
models.
Service Channel
The Service Channel provides a transparent ASCII “pipe” to which any
RS-232/EIA-232 device can be connected at data rates between 300 and
9600 bps. Whatever ASCII data is entered onto the network through the
Service Channel Port will be sent to the local radio and broadcast to any
other device connected to the Service Channel Port on other associated
LEDR radios in the network.
The Service Channel’s function is identical for all LEDR configura-
tions—stand-alone, repeater, and redundant.
NOTE: Use of the orderwire will slow down data communications on
the Service Channel. It will not effect data traffic on the
primary data interface.
For detailed information on this 9-pin connector, see “Service
Channel—Rear Panel” on Page 129.
