Serial Fpdp Cable Connections; Lan Configuration -- Recorder/Agilent E9821 Dsp Devices Only - Agilent Technologies E3238S Installation And Configuration Reference

Hardware Installation
If the configuration requires multiple LAN devices to be connected to the
Agilent E9821 DSP LAN port, a 100-baseT LAN hub or switch must be used. In this
case, crossover cables cannot be used. Configurations that use an Agilent PSA as a tuner,
but also require an Agilent 35688E Option WRP, Wideband Recording and Playback
Subsystem would encounter this configuration.

Serial FPDP Cable Connections

The serial FPDP connector labeled "Port 1" on the recorder is connected to the ADC (Agilent
E1439 or Agilent N6830)
Connections for Serial FPDP Cables
This is a full duplex connection -- Rx to Tx and Tx to Rx.
The "Port 2" connector is connected to the Agilent E9821 DSP "Port A" serial FPDP
connector. If the configuration is using a single Agilent E9821 DSP, a simple duplex
connection is made -- Rx to Tx and Tx to Rx.
If the configuration has multiple Agilent E9821 DSPs, the cabling depends on whether
delay is being used for narrowband processing (specified in the configuration file, for
example,
searchRx1:minDelayTimeRequired:0.5
• If delay is not being used, the FPDP cables are connected as shown in the Agilent
E3238S Installation and Configuration Reference in the VHF/UHF Single Channel
Configuration, Multiple DSPs with no Delay section, except the ADC connection is
connected to "Port 2" of the recorder. In this configuration, sFPDP "Port B" on the
Agilent E9821 DSP modules are not used.
• If delay is being used, the FPDP cables are connected as shown in the Agilent E3238S
Installation and Configuration Reference in the VHF/UHF Single Channel
Configuration, Multiple DSPs with Delay section, except the ADC connection is
connected to "Port 2" of the recorder.

LAN Configuration -- Recorder/Agilent E9821 DSP Devices Only

The network IP addresses for the recorder and the Agilent E9821 DSP have been set
when configured at the factory for new systems. The recorder's address is 10.1.249.101
and the Agilent E9821 DSP's address is 10.1.249.100. Connect the two LAN ports
using a crossover cable (also referred to as a direct connection or loopback cable). You
can also use a standard LAN cable with a crossover adaptor.
