Radio Network Overview
The radio network with ultra high frequency (UHF), 900
MHz, or 2.4 GHz radio products enables a user to operate
an INTERMECRwireless terminal emulation station as if
it was a VT220 terminal. The mobility of the wireless station enables the user to take it any place in the facility and
interface with a large variety of networks and host computers. This results in increased data collection, improved
time control, and the ability to run a large number of applications without the need to custom program, change software, or learn new programming languages or protocols.
The radio network also:
" Provides industry standards.
" Supports Ethernet Version 2 (DIX) and IEEE 802.3,
and these connections: 10BASE2 (thin), 10BASE5
(thick), and 10BASE-T (UTP).
" Automatically recognizes the model of the wireless
station on the network. Wireless station models that
support VT220 terminal emulation are RT3210,
RT1100, RT1700, and RT5900 Radio Terminals; and
PEN*KEYR6400 and 6500 Computers.

RT3210 Radio Terminal
" " " " " " " " " " " " " " " " " " " " " " " " " " " "
VT220/ANSI Display Emulation
The RT3210 Radio Terminal’ s 128 by 128 pixel liquid crystal display (LCD) shows radio terminal and VT220 prompts,
and information you type. Because the VT220 terminal’s
screen is 80 columns by 24 lines, the radio terminal represents a part of the information on the larger VT220 screen.
"
NOTE: RT3210 Radio Terminals have UHF radios only.
Character Sizes
The radio terminal supports two character sizes: 7-by-9 dot
and 5-by-7 dot. The sizes affect how much information appears in the display; each dot occupies one pixel. The
5-by-7 dot characters are smaller , but let you view a larger
portion of the 1920-byte screen represented on the VT220
terminal. To change the character size, open the firmware
by pressing [FUNC]+[SPACE]. Then select the following
options in this order: SET-UP PARMS (password:
CR52401), DISPLAY OPTS, CHARACTER SIZE.
VT220/ANSI Terminal Emulation Programmer’s Reference Guide 2-1
SECTION 2 " RT3210 Radio Terminal
When the radio terminal powers up, it defaults to a 7-by-9
dot character size. This size is the larger of the two character sets, and yields a screen size of 16 columns by 9 lines of
display information (the bottom line is reserved for annunciators and system messages). The total number of characters this size can display is 144.
The 5-by-7 dot character size yields a screen size of 21 columns by 15 lines (the bottom line is reserved for annunciators and system messages). The total number of characters
this size can display is 315.
Screen Modes
The radio terminal has these screen modes: center cursor ,
corner , page, lazy, screen lock, and locked. The modes present a window onto a standard VT220 display buffer . You
can set the type of screen mode through the radio terminal’s
firmware menus.
You can move the cursor by using the four direction arrows
on the radio terminal’s diamond-shaped keypad. When you
try to move the cursor onto one of the boundaries, an error
tone sounds and the display retains its last position.
The screen modes govern which portion of the larger VT220
terminal’s screen the radio terminal first presents and how
the window moves as the cursor moves.
Center Cursor Mode
Center cursor mode works best for applications that use the
entire VT220 data stream’s 80-character by 24-line logical
display. In this mode, the cursor remains in the center of
the radio terminal’s window.
2-2 VT220/ANSI Terminal Emulation Programmer’s Reference Guide
SECTION 2 " RT3210 Radio Terminal
As the cursor moves within the window, the radio terminal’s
display window moves to keep it centered. When the cursor
moves off the right, left, top, or bottom edge of the VT220
terminal’s display, the window remains fixed despite the
cursor’ s movement.
Corner Mode
Corner mode begins with the window in the upper left corner of the larger VT220 terminal. It keeps the cursor in the
lower right corner of the display. Corner mode works best
for applications that use the upper left corner of the logical
screen.
As the cursor moves off the right or bottom edge of the radio
terminal’s display, the window moves to show the cursor.
When you use corner mode with the [FUNC] or [ALT] key,
you can move the cursor a predetermined number of key
presses in all four directions.
Page Mode
Page mode provides predefined pages within the larger
VT220 terminal. The size of these pages depends on the
number of rows and columns selected for display. The radio
terminal moves the window by a multiple of the page size.
As the cursor moves off the edge of the radio terminal’s display, the window changes to the next page.
Lazy Mode
Lazy mode starts the cursor in the upper left corner of the
display. The cursor moves across the display in the scrolled
direction. When the cursor goes beyond the edge of the display, the data begins to move in the scrolled direction and
the cursor remains at the edge of the display. When you try
to go beyond an outside boundary, an error tone sounds.
VT220/ANSI Terminal Emulation Programmer’s Reference Guide 2-3
SECTION 2 " RT3210 Radio Terminal
Locked Mode
If locked mode is selected through the firmware menus, the
view window is locked to the upper left-hand corner of the
display. The screen does not window around, and only the
area that has been selected to be the screen size is visible.
Locked mode disables the windowing keys, or only allows
you to window around the physical display size selected
through the firmware menus.
Display Annunciators
The bottom line of the radio terminal’s display is reserved
for annunciators that show the radio terminal’s current status or operation in progress. The following annunciators
can appear .
The radio terminal is transmitting information
to the base station.
The radio terminal is receiving information
from the base station. This annunciator appears
only when the information is for the radio terminal’s unique address number.
Communications loss. No communication
with the host computer has occurred for at least
60 seconds. The radio terminal may be out of
radio range, the base station may not have power, or communications from the host computer to
the base station may not be properly set up.
Radio terminal’s keyboard is in function mode.
The key you press on the keyboard with [FUNC]
returns the function or programmable function
key code assigned by the programmer, or does
an operation. Key codes and operations are located just above the keys and to the left (black
lettering).
