EIA232 Pin Specifications
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 configuration. 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 commu-
nications 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.
Monitoring & Alarms
There are no physical connections provided to specifically communicate system or alarm
status. This information is embedded in the information accessible via the communication
ports described earlier.
USB Interface
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 software updates and filter file
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.
