Electrostatic Discharge (ESD)
Electrostatic discharge (static electricity) can have unpredictable
adverse effects on any electronic device. Although the design of the
HV ANSI Series incorporates extensive ESD-related precautions, ESD
can still cause problems. It is good practice to discharge static by
touching a grounded metal object before inserting cards or
connecting devices.

1. A linear regulator (7805A) with a minimum input of 7.5 V and a maximum voltage of 28.0 V that dissipates one watt of
power thereby limiting maximum permissible input voltage according to current draw of terminal.
2. A switching type voltage regulator with a minimum input of 9.0 V and a maximum voltage of 28.0 V. Since input
voltage is not dependent on the terminal’s current draw, it is suitable for all options.

Power Requirements
Power Supply Options
Depending on the current draw requirements, the terminal may require the use of different power
supplies. Use the configuration number listed below (see previous page) to determine the correct power
supply:
•"-1"—requires connection to a 5-volt ± 5% regulated power source.
•"-2"—requires connection to a power source between 7.5 and 12 VDC that can source adequate
current. However, depending on a unit's total current draw, an input of up to 28 VDC may be
applied. See chart on next page.
•"-H"—requires connection to a power source between 9.5 and 28 VDC that can source
adequate current. However, input voltage is not dependent on a terminal’s current draw and
may be used with all terminal options.
Calculating Total Current Draw
The table below summarizes the current draw requirements for HV ANSI Series terminals in various
configurations (measured at its interface connector). Values listed are approximate due to variations in
individual components—actual values may vary.
Current Draw for Basic Configuration
Configuration Description Draw
HVR2 Base Unit with RS-232 35 mA
HVR4 Base Unit with RS-422 33 mA*
Current Draw for Options
NL LED Supertwist Backlit Add 185 mA
NEL/TEL Supertwist Backlit/Extended Temperature Backlit Add 45 mA
VFD/TVFD Vacuum Fluorescent Display/Extended Temperature VFD Add 300 mA
KL Backlit Keypad Add 80 mA
LED LED Indicators Add 4 mA per LED
Operational Current Requirements
Handshake Low Add 3 mA
Handshake Floating (not connected) Add 1 mA
*Worse case measurement, based on 4000 feet of cable, terminated with a 120-Ohm resistor.
To calculate the total current draw for your terminal configuration:
1. Read the model number on the back of your terminal.
2. Using the model number and the table above, add the current draw for each option to that of
the base unit.
Example 1—HVNEL30R2-ANSI:
RS-232 Option 35 mA
Supertwist Backlit Display 45 mA
Calculated Total Current 80 mA
Example 2—HVNL30KLR2-ANSI:
RS-232 Option 35 mA
LED Supertwist Backlit 185 mA
Backlit Keypad 80 mA
Calculated Total Current 300 mA

Determining the Maximum Input Voltage Allowed
The maximum input voltage allowed is based on a unit’s current draw.
To determine the maximum input voltage allowed based on current:
1. Calculate the maximum current draw using the table on the previous page.
2. On the following chart, locate the Calculated Total Current on the Calculated Operating
Current axis of the chart, and then move to the top of Operating Voltagerange.
3. Look at the corresponding Maximum Input Voltage Allowed where the intersection occurs to
find the maximum useable voltage for your terminal configuration.

Calculated Operating Current (mA)
Maximum Input Voltage Allowed
Using Example 1 and the chart above, the 80 mA drawn by the HVNEL30R2-ANSI intersects with
17.50 volts. If the maximum supply voltage to the terminal is greater than 17.50 VDC, it requires a -
H power supply configuration.
Using Example 2 and the chart above, the 300 mA drawn by the HVNL30KLR2-ANSI intersects
with 8.33 volts. If the maximum supply voltage to the terminal is greater than 8.33 VDC, it requires
a -H power supply configuration.
To clarify, if your system is supplying 12.00 VDC, the power is acceptable for the HVNEL30R2-
ANSI (Example 1), but not for the HVNL30KLR2-ANSI (Example 2). Applying 12.00 VDC to the
HVNL30KLR2-ANSI (Example 2) will damage it.

Overview
1-2
About the HV ANSi Series
Specifically designed for industrial applications, HV ANSI Series terminals are rugged with fully
functional ASCII capability and selectable operating parameters.
You can change nearly every aspect of its operation from display mode to function key definitions via
menu selections or direct host control using ANSI and Private mode escape sequences.
HV ANSI Series Features
Two Technologies offers the HV ANSI Series with the following features. You can find additional
information regarding specifications in Appendix A.
Display
HV ANSI Series terminals come with a standard 80-character monochrome liquid crystal display that
features the standard U. S. ASCII character set as dark characters on a light background. Cursor and
view angle settings for the display can be menu or host-controlled.
Backlit and extended temperature displays, as well as optional character sets, such as Latin 1 or
European are also available. HV ANSI Series terminals also give you the ability to create up to three
custom characters not supported in the display's font table.
Keypad
Securely framed and clamped into place, the keypad surface provides excellent splash resistance and
prevents curling or peeling of the keypad overlay. Standard keypad layouts include 20 (4 rows x 5
columns) and 30 (6 rows x 5 columns) keys available with standard or custom graphics. Keypads can be
made from your choice of elastomeric or membrane material.
Options for 40-key HV ANSI Series terminals include up to five 5 LEDs (across the top row) a backlit
keypad. Custom keypad layouts are also available.
Switches and Indicators
You can program up to five function keys (keyboard dependent) with up to 20 characters each and
store this information in non-volatile memory.
Five host-controlled LED indicators (located within each key on the top row) are available as an option
on 40-key HV ANSI Series terminals ordered with ANSI compatibility.
Interface Options
Interface options include RS-232, RS-422 and CMOS/TTL protocols. Communication (up to 19,200 bps
standard, higher speeds available on a custom basis) with a host device is through a modular 6-pin
connector.
Durability
Like all Two Technologies' products, the HV ANSI Series terminal is remarkably rugged. The case
consists of Bayblend ABS polycarbonate blend, one of the most durable, chemical-resistant materials
available on the market today.

1. Plug one end of a 1210 modular cable into the modular connector on the bottom of the
terminal. Plug the other end into the PCAT adaptor.
2. Plug the PCAT adapter into the host device.

2. Using a Two Technologies’ power supply (such as a Two Technologies 1226-1 linear power
supply for units with a -2 power supply configuration), plug the power supply connector into
the PCAT adapter and then plug the power supply into a 120 VAC 60 Hz power outlet.
3. The terminal should turn on and a blinking cursor should appear on the display. If the
terminal does not turn on, refer to the Troubleshooting section of this manual for help.
Display Operation
Standard HV ANSI Series terminals display the U.S. ASCII 96 character set. However, other character
sets, such as such as Latin 1 or European, are also available as an option. Characters appear on the
display at the current cursor location.
Cursor Position
Typically, the cursor moves from left to right as the terminal displays characters (unless altered by
Escape commands). The cursor is selectable as a block (enabled), hidden (disabled), blinking and non-
blinking.
Whenever a character appears in the last position of the top three rows, the cursor will move to the
leftmost position on the next row. By default, the terminal will hide the character in the last position on
the bottom row (Position 80) with the cursor until it displays the next character. In which case, the
screen will scroll up one row, the hidden character will appear in Position 80 and the cursor will appear
in the rightmost position on a new bottom row. As an option, you can display a character in Position 80
and hide the cursor before the terminal display the next character.
For additional information about cursor and display options, see Chapter 3: Manual Configuration, and
Chapter 5: ANSI Mode Host Commands.

Keypad Operation
The standard 30 position keypad consist of uppercase letters, digits 0 through 9, punctuation marks,
symbols, function keys and keys for Escape (ESC), Space (SPACE), Backspace (BACKSP/BKSP),
Control (CTRL), Shift (SHIFT) and Enter (ENTER). You can program the SHIFT key to operate in
normal or locked mode. In the locked mode, pressing a modifier key will toggle its respective state.
Transmission of control characters will cancel the control state. If both the Shift and Control states are
active, lowercase alphabetic characters will replace corresponding uppercase alphabetic characters. All
keys, with the exception of CTRL and SHIFT, may be re-assigned with user-programmed characters or
character strings from the key output definition menu. For information about control states, refer to the
Shift Lock parameter setting.
On terminals with 30 and 40-key keypads, you can program up to ten function keys. On terminals with
20-key keypads, you can program up to four function keys. You can change these values and enter up
to 20 characters per key (including non-printing characters) or enter special hex codes to control the
transmission and display of characters between the host and terminal. For more information, see
Chapter 4: Function Key Programming.
The standard 20 position keypad consist of the digits 0 through 9, functions keys and keys for Yes
(YES), No (NO), Backspace (BKSP), Space (SPACE) and Enter (ENTER).

LED Indicators
Five host-controlled LED indicators are available as an option on HV ANSI Series terminals with 30 and
40 position keypads (four LED indicators are available for terminals with 20 position keypads). LEDS
indicators are available in red, amber or green. You can control the LEDS by using ANSI Escape
commands. See Chapter 5: ANSI Mode Host Commands for more information.

Operating Modes
HV ANSI Series terminals have several operating modes. The default mode is Terminal mode. It allows
the terminal to display characters, respond to commands sent by a connecting device, and send
characters to the connecting device as keys are pressed. Other modes, described later in this manual,
enable you to set operating parameters and program function key definitions.
Host Control
The design of HV ANSI Series terminals allows a connecting device (or “host”) to control its functions
through the transmission of a string of special characters.
Referred to as “Escape commands” (because each character string begins with the ASCII escape
character), these character strings enable the host to move the cursor to any position on the display,
clear selected regions of the display, sound a beep, alert or key click, program the function keys and set
any of the operating parameters.
HV ANSI Series terminals have two sets of built-in Escape command modes, ANSI and Private. The set
in use is determined by the setting of the Escape Mode parameter.
When set to ANSI mode, the terminal recognizes a command set compatible with the American
National Standards Institute Standard X3.64.
When set to Private mode, the terminal recognizes a smaller, non-standard set of commands.
The host can change the current Escape mode type at any time by issuing the corresponding Escape
command.
Information about using ANSI and Private Mode Escape commands appears later in this manual.
