A-1 Append ix A Terminal Configu rator This append ix describes how t o use t h e Terminal Config urator to configure t he Ethernet Adapter. The Terminal Config urator is an alternate method used to configure your Ethern et Adapter. The Terminal Configu rator is a text-based configu r ation method.
Establi shing a Dir ect Serial Co nnection A-2 Establish ing a Direct Seria l Connection This method of configuring and managing an Ethernet Adapter uses a serial cable connected from the Ethernet Adapter to a computer runn ing terminal emulation software.

Establi shing a Telne t Connecti on A-4 Establishing a Telnet Connection This metho d opens a Telnet co nnection to the Terminal Co nfigurator on port 23. Port 23 is the default for most Telnet programs. This only works after the Ethernet Adapter is assigned a TCP/IP address.
A-5 Using the Termin al Conf igu ra tor Main Menu Over vie w The sec tion provi des a list of main m enu selections and their functio ns. Resume operation This option exits Configu ration. It returns the Ethernet Adapter to the setting s the Ethern et Adapter had before the Configure b utton was pressed.
Using the Terminal Con figurator A-6 Edit Configura tion Menu The Edit Configuration menu contains three selectio ns/Config files to edit. Return to Main M en u Goes back to the pr evious menu selections. System Brings up the editor screen wit h the configuration file for o ptions that are not communication d ependent.
A-7 Using the Termin al Conf igu ra tor Configuration File Format The configurat ion file format is broken down in to sections that define a particular grouping of options. Each section con tains at the top a section hea d er which is a string of text surrounded by square brackets: [ ] (the section title).
Using the Terminal Con figurator A-8 [bridge] Bridge provides variabl es that are common to all radios. Br idge affects th e behavior of radios . AP refresh period . Periodically an Ethernet Adap ter pings an Access Point. The AP Refresh Period is the time, in units of seconds, between pings.
A-9 Using the Termin al Conf igu ra tor [software] The [software] section is used to contro l the r eceiving and sending of bytes over the serial port. Proper setting of th es e values can significantly enhance the efficiency of data transmission because the radio is “packet based” an d the UART is “stream based.
Using the Terminal Con figurator A-10 transmitted immediately. Conversely, if another character is received before this time-out, the tim er is res tarted from th e beginning. The range for this valu e is from 10 t o 65536 mi llisecond s, th ough it wil l always rou nd up to the nearest tens of milli seconds.
A-11 Using the Termin al Conf igu ra tor [flow control] The Ethernet Adapter supports the following six f l ow control op ti ons: Recognize RTS, Generate CTS, Recognize DTR, Generate DSR, Recognize XON/XOFF, and Gener ate XON/XOFF.
Using the Terminal Con figurator A-12 immediately; otherwise, all of the d ata thereafter would be lo s t.) The h o st computer, however, woul d have t o ask permission fro m the modem to send data. The host would d o this by asserting the RTS line. Th e modem would see this, and check to see if it were ready to accept data.
A-13 Using the Termin al Conf igu ra tor CTS an d DSR are out put lines. When set to “negate” or “assert,” t hey will output a continuo us digital value. The value “negate” outp uts a logic 1, or “mark” which is electrically negative. This is also the state seen on an RS-2 32 co nne ctor when the cab le is unplugged.
Using the Terminal Con figurator A-14 [telnet] The following section specifies the opera t ing parameters for the Telnet protocol. • connect . This entry dictates what kind of prompt is seen on the serial port output. The two choices available are: wait for keystroke and comm and prompt.
A-15 Using the Termin al Conf igu ra tor Network Bindings This section describes the mean ing behind each of the entries that describe network bind ing. [rmpbind] This bindi ng can be used for both the passthro ugh protocol and fo r the I/O control socket setting.
Using the Terminal Con figurator A-16 • transmit retry int erval . When attempting additio nal transmit attempts as specified with “transmit try count” above, it can be useful to additi onally specify how l ong to wait betw een attempts. Thi s setting determ ines the time period for retransmission attempts.
A-17 Using the Termin al Conf igu ra tor • serial connect data . The fo rmat is the same as in socket connect data. This causes data to be written to the UART once a connection is successful. • serial disconnect data . This causes data to be written to the UART when the networ k connecti on has been clos ed.
Using the Terminal Con figurator A-18 [e ncry ption] This value uses the RC4 algorithm as defined in the IEEE Wired Equivalent Privacy (WEP) standard to encrypt da ta. Enter up to four keys. The stan dard RoamAbout PC C ard supports th e 40-bit encrypti on only.
