Westell Inc. CSI-DSP85-U7C ユーザーズマニュアル

-8-

The diagram to the left is for reference only, it’s intended to provide
a quick source for pinout information in the event it should be
necessary to adapt your serial cable because of an unusual
connector configuration.  In the vast majority of cases this
information will not be needed.

To allow monitoring and control, the repeater is equipped with four ports that provide external communication access (1 Ethernet
CAT-5, 2 DB-9 serial, and 1 USB). The Ethernet, CAT-5 port is provided as a primary communications port to the PC. One serial
interface provides communications to local PC and the second to an external modem when provided. The  USB interface provides a
means to download files from a memory device and may also be used by an external modem.  The DB-9 pin assignments conform
to the standard Electronic Industries Association (EIA232) specification. A diagram of the pin descriptions is provided on this page
for reference.

Connecting a null modem cable to one of the COM ports and using a terminal emulation program with a PC will allow communication
to the control processor’s Text Menu Interface (TMI). See command line interface section for further detail.

The minimum measurable input level is -81 dBm at 85 dB gain, -71 dBm at 75 dB gain,  -61 dBm at 65 dB gain, and -51 dBm at 55 dB gain.

The Universal Serial Bus (USB) interface conforms to
Intel’s Universal Host Controller Interface (UHCI) version
1.1 dated March 21, 1996. This interface will support data
transfer rates up to 12 Mbps and can be used for soft-
ware updates and filter file uploads.

Note:  During Power up, the unit will require a approximately three minutes for the internal computer to boot up. During this time

the LEDs on the front panel will light and go out several times. When boot  is complete and no alarm conditions exist, none of the LED
indicators will be illuminated. The CSI logo is illuminated when ever the repeater is powered. One or more bars on the LED bargraph
may also be lit, depending on the strength of the signal being received from the donor site. Signals weaker than -81dBM will not
illuminate any bars.

                                     

The Ethernet AUI conforms to IEEE 802.3 and is capable of
supporting 10/100 Mbps communications speeds. This port is
used to provide access to the GUI.
