EIA232 Pin Specifi cations
USB Interface
The Universal Serial Bus (USB) interface conforms to Intel’s Universal Host Control-
ler 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 software updates and fi lter fi le uploads.
Ethernet
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.
Monitoring & Alarms
There are no physical connections provided to specifi cally communicate system or alarm
status. This information is embedded in the information accessible via the communica-
tion ports described earlier.
The diagram above 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 confi guration. In the vast majority of
cases this information will not be needed.
Local Communication Interface Ports
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 fi les 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) specifi ca-
tion. 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 emula-
tion program with a PC will allow communication to the control processor’s Text Menu
Interface (TMI). See command line interface section for further detail.
