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.

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).
2-4 VT220/ANSI Terminal Emulation Programmer’s Reference Guide
SECTION 2 " RT3210 Radio Terminal
The radio terminal’s keyboard is in alternate mode. The key you press on the keyboard in
combination with [ALT] types the character or does the operation just above the key and to the right (yellow lettering).
The radio terminal’s keyboard is in control mode. The key you press on the keyboard in combination with [CTRL] generates the 7-bit control character commonly used in DEC ap­plications.
The battery needs to be recharged. When this annunciator appears, you have only two minutes of operating time left before the radio terminal disables operator input and radio communica­tions. After two minutes, the message “CONNECT UNIT TO CHARGER” blinks.
Recharging. The radio terminal is connected to a battery charger.
The radio terminal’s battery pack is fully charged. This annunciator is used by the fast charge algorithm to indicate the fully charged condition.
High speed. The base station is transmitting information at 9600 baud (versus 4800 baud).
Radio terminal’s keyboard is in character mode (versus line edit mode). The radio termi­nal is sending, to the host computer, each key as you press it. (No annunciator appears for line edit mode.)
The radio terminal’s keyboard is in shift lock mode. The letters you press on the keyboard after you press [SFT] will be in uppercase, until you press [SFT] again.

VT220/ANSI Display Emulation
The RT1100 Radio Terminal’ s 128 by 128 pixel liquid crys­tal displays (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: Radio terminals in the RT1100 Series have UHF, 900 MHz, or 2.4
GHz radio modules.
Host V iew Size
For VT220 terminal emulation, the host view size is 24 characters high by 80 characters wide.
Screen Size
You can select the number of display lines and characters per line. The options are 12 or 16 characters per line by 4, 6, 8, or 9 lines.
VT220/ANSI Terminal Emulation Programmer’s Reference Guide 3-1
SECTION 3 " RT1100 Radio Terminal
The default is 9 lines and 16 characters. To change the screen size, open the firmware and then select the following options in this order: LCD PARMS, SCREEN SIZE.
Screen Modes
The radio terminal has these screen modes: center cursor , corner , page, lazy, screen lock, screen lock, and locked. The modes present a window onto a standard VT220 terminal’s 80-character by 24-line display buffer . You can set the type of screen mode through the radio terminal’s firmware menus.
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.
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, 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.
3-2 VT220/ANSI Terminal Emulation Programmer’s Reference Guide
SECTION 3 " RT1100 Radio Terminal
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 gold-colored 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.
Screen Lock Mode
Screen lock mode allows a specified screen size to be set up and locked. Only the commands issued to the selected screen size are operated on. For example, if the host sends characters to the display, and the number of characters to display is greater than the number of columns specified, the last column(s) on the screen are overwritten.
VT220/ANSI Terminal Emulation Programmer’s Reference Guide 3-3
SECTION 3 " RT1100 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.

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 terminal’s 80-charac­ter by 24-line display buffer . You can set the type of screen mode through the radio terminal’s firmware menus.
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.
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 larger 80x24 display, the window remains fixed despite the cur­sor’ s movement.

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 move the cursor beyond an outside boundary, an error tone sounds.
Screen Lock Mode
Screen lock mode allows a specified screen size to be set up and locked. Only the commands issued to the selected screen size are operated on. For example, if the host sends characters to the display, and the number of characters to display is greater than the number of columns specified, the last column(s) on the screen are overwritten.
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.

37-Key Keyboard
The 37-key keyboard (Figure 4-2) has standard numeric and [ENTER] keys, plus application-defined function keys. It does not have alphabetic keys in its primary plane.
Because a radio terminal with a 37-key keyboard does not have alphabetic keys in its primary plane, follow these pro­cedures when using its firmware and downloading software:
" To access password-protected menus, press [F12] and
then [F11], and enter the password. For example, the password for the SET-UP PARMS menu is 52401.
" To initiate the COLD START? menu option, press
[F10] to answer “yes.”
" To download software, hold down the [F1] key as you
power up the radio terminal to go into download mode. This is similar to holding down the [I] key on the stan­dard 57-key keyboard.

If you try to move the cursor off the display in any direction, the window shifts one or eight lines or columns in the direc­tion of the cursor movement. This lets you move the view­ing window around within the larger VT220 terminal screen. The display does not wrap when the window reach­es the top or side boundaries of the virtual VT220 screen. A beep tone sounds when you try to move the window beyond a top, bottom, left, or right boundary.
Use the arrow keys in combination with [GOLD] and [BLACK] to move through the radio terminal’s display a single space at a time (indicated by “S” on the overlay) or eight spaces at a time (indicated by “W” on the overlay). The following chart shows key movements.

VT220/ANSI Display Emulation
The RT5900 Mobile Mount Radio Terminal’ s display 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: RT5900 Series radio terminals have UHF, 900 MHz, or 2.4 GHz
radios.
Host V iew Size
The host view size is 24 characters high by 80 characters wide.
Screen Size
You can select the number of display lines and characters per line. The options are 40, 60, or 80 characters per line by 8, 10, 12, 16, 21, or 25 lines. The default is 12 lines and 40 characters. To change the screen size, open the firmware and then select the following options in this order: LCD PARMS, SCREEN SIZE.
VT220/ANSI Terminal Emulation Programmer’s Reference Guide 5 -1
SECTION 5 " RT5900 Radio Terminal
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 terminal’s 80-charac­ter by 24-line display buffer . You can set the type of mode through the radio terminal’s firmware menus.
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.
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, 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 brown-colored key, you can move the cursor a predetermined number of key presses in all four directions.
5-2 VT220/ANSI Terminal Emulation Programmer’s Reference Guide
SECTION 5 " RT5900 Radio Terminal
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.
Screen Lock Mode
Screen lock mode allows a specified screen size to be set up and locked. Only the commands issued to the selected screen size are operated on. For example, if the host sends characters to the display, and the number of characters to display is greater than the number of columns specified, the last column(s) on the screen are overwritten.
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.

Special Function Keys
Table 5-2 describes how to use the radio terminal to do spe­cial VT220 terminal function operations. Note that the ra­dio terminal does not support key operation COMPOSE CHARACTER, which creates characters that do not exist as standard keys on the VT220 keyboard.
Operation of the delete key depends on how the PROTO­COL OPTS parameter is set in the radio terminal’s firmwa­re. The key either sends a delete (DEL, 7F hexadecimal) or a backspace (BS, 08 hexadecimal).
To change from delete mode to backspace mode, open the firmware by pressing [BROWN]+[SPACE]. Then select the following options in this order: SET-UP PARMS (password: CR52401), PROTOCOL OPTS, VT220, DEL TO BS.

If you try to move the cursor off the display in any direction, the window shifts one or eight lines or columns in the direc­tion of the cursor movement. This lets you move the view­ing window around within the larger VT220’s screen. The display does not wrap around when the window reaches the top or side boundaries of the virtual VT220 screen. A beep error tone sounds when you try to move the window beyond the top, bottom, left, or right boundary.

The PEN*KEY 6400 Computer’ s liquid crystal display (LCD) shows PEN*KEY computer and VT220 prompts, and information you type. Because the VT220 terminal’s screen is 80 columns by 24 lines, the PEN*KEY computer repre­sents a part of the information on the larger VT220 screen.
Screen Size
You can select the number of display lines and characters per line. The options are 3, 6, 9, or 18 lines by 10, 13, 16, 20, 26, or 32 characters per line. To set the screen size open the firmware and select the following options in this order: LCD PARMS, SCREEN SIZE.
Screen Modes
The PEN*KEY computer has these screen modes: center cursor , corner, page, lazy, screen lock, and locked. The modes present a window onto a standard VT220 terminal’s 80-character by 24-line display buffer . You can set the type of screen mode through the PEN*KEY computer’ s firmware menus.
VT220/ANSI Terminal Emulation Programmer’s Reference Guide 6 -1
SECTION 6 " PEN*KEY 6400 Computer
The screen modes govern which portion of the larger VT220 terminal’s screen the PEN*KEY computer 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 PEN*KEY computer’ s window.
As the cursor moves within the window, the PEN*KEY com­puter’ s display window moves to keep it centered. When the cursor moves off the right, left, top, or bottom edge of the larger 80x24 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 PEN*KEY computer’ s display, the window moves to show the cursor . When you use corner mode with the gold-col­ored 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.
6-2 VT220/ANSI Terminal Emulation Programmer’s Reference Guide
SECTION 6 " PEN*KEY 6400 Computer
The PEN*KEY computer moves the window by a multiple of the page size. As the cursor moves off the edge of the PEN*KEY computer’ 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 move the cursor beyond an outside boundary, an error tone sounds.
Screen Lock Mode
Screen lock mode allows a specified screen size to be set up and locked. Only the commands issued to the selected screen size are operated on. For example, if the host sends characters to the display, and the number of characters to display is greater than the number of columns specified, the last column(s) on the screen are overwritten.
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.
