Terminal Operation 4-1 PRISM 4001
4. Terminal Operation
This chapter describes the screens and menus associated
with the TxPORT P
RISM 4001 Terminal Interface, a firm-
ware application embedded within the 4001. Refer to the
Installation chapter for connection information. Cables are
available from TxPORT for most typical connections and
are listed in Table 1-C on page 4-4. If necessary, contact
TxPORT for assistance in cable selection.
System Description
The Terminal Interface requires either an ANSI-compatible
VT100 terminal (ASCII), or a computer running an ANSI
terminal emulation program. The Terminal Interface utilizes
ASCII break and escape functions; these functions are
implemented differently by the various terminal emulation
programs. For further reference, consult the documentation
supplied with the terminal emulation program.
Once a compatible terminal is properly connected to the
4001, a terminal interface session can be started by sending
a break to the 4001, or by pressing ENTER four times. The
Main Menu screen (Figure 4-1) is then displayed.
Configuration
The P RISM 4001 can be configured via the menu driven ter-
minal interface described in this chapter. The terminal must
be connected to the 8-pin serial RS-232 level S
UPV port on
the front panel. Although the S UPV port must be used for a
Terminal Interface connection, the user may also connect to
the 4001 through an 8100A Site Controller. Bit rates from
1.2 to 19.2 kbps may be selected.
When the 4001 is powered up, it is configured as specified by
SW2 switches 7 and 8 (from SAVED, default, or the other
switches). The terminal interface has a configuration screen
for both the network line connection and the DTE port con-
nection. Each configuration screen may have a field which
allows the user to access the far-end unit’s corresponding
configuration screen when operating in TxPORT mode.
Refer to section Utilities Screen on page 4-13 for
information on saving a custom configuration.
Modem Compatibility
The 4001 supports an AT-command-set-compatible modem
on the S
UPV port. Set the modem to ignore DTR, enable
auto answer, inhibit command echo, and return verbose
result codes.
The modem hangs up if the user calls the 4001
and presses any key before receiving the connect
message. This is caused by the any-key-abort
feature of the modem, not the PRISM 4001.
Screen Components
Terminal interface screens have several components com-
mon to all screens and are discussed individually in the fol-
lowing paragraphs. The common elements are displayed in
the Main Menu (Figure 4-1).
D EVICE T YPE AND R EVISION
The device type (such as P RISM 4001) and the revision con-
trol numbers are shown in the upper left corner. The first
number is the hardware revision and the second is the soft-
ware revision. Information is displayed for the near-end unit
(connected directly to the terminal) on the top line, and for the
far-end unit (connected to the network interface) on the sec-
ond line. Refer to this information when contacting the fac-
tory with inquiries. The far-end information is available only
if the far-end unit is a TxPORT product and is set for
TxPORT operation which supports a proprietary message set.
