EIA232 Pin Specifications
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 CSI-DSP85-PSS8 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 assign-
ments 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 repeater 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.
Do not unplug the unit while it is in the boot up process!
Local Communication Interface Ports
USB Interface
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.
