Warranty Information
Seller warrants that the product specified in this agreement are free of defects in materials and
workmanship, and shall conform to the latest specifications published prior to Buyer’s acceptance of the
agreement for a period of three years.
Product specifications as defined supersede previous specifications and are complete. Any parameter
that is not specifically defined in the specifications is expressly excluded from the warranty. This
warranty does not apply to any product which have been subject to misuse, accident, alteration, or if
the unit has been serviced by anyone other than an authorized representative of Seller.
Seller’s sole obligation to Buyer for products failing to meet specifications shall be, at Seller’s discretion,
to repair or replace the non-conforming device.
After receiving a Return Authorization (RA) number and a mailing address from Seller, a defective unit
covered under this warranty may be returned freight prepaid. Any replacement or repaired product
shall carry only the unexpired term of the warranty plus any the period required for repair.
If Buyer has been expressly designated as an Original Equipment Manufacturer (OEM) by Seller, the
warranty period shall commence upon the earlier date of (i) delivery to Buyer’s first customer, or (ii)
180 days from the original date of shipment by Seller. In the events that products for which: (a) Buyer
has title and, (b) have never been used, and (c) have been in the Buyer’s possession for more than 180
days and, (d) have an unaltered date code attached, may for an established fixed fee which will not
exceed ten percent (10%) of the original purchase price, have the date code updated by the Seller and
thereby reestablish those products with a new warranty.
THE FOREGOING WARRANTY AND REMEDIES ARE EXCLUSIVE AND ARE MADE EXPRESSLY
IN LIEU OF ALL OTHER WARRANTIES EXPRESSED OR IMPLIED, EITHER IN FACT OR BY
OPERATION OF LAW, STATUTORY OR OTHERWISE, INCLUDING WARRANTIES OR
MERCHANTABILITY AND FITNESS FOR USE. TWO TECHNOLOGIES NEITHER ASSUMES NOR

Regulatory Notices
FCC Compliance
This equipment has been tested and found to comply with the limits for Class A digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a commercial environment. This equipment
generates, uses, and can radiate radio frequency energy and, if not installed in accordance with the
instruction manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference, in which case the user will be
required to correct the interference at his or her own expense.
Canadian Compliance
This digital apparatus does not exceed the Class A limits for radio noise emissions from digital
apparatus set out in the Radio Interference Regulations of the Canadian Department of
Communications
Le present appareil numerique n.emet pas de bruits radioelectrique depassant les limites applicables
aux appareils numeriques de la class A prescrites dans le Reglement sur ie broullage radioelectrique
edicte par le ministere des Communications du Canada.

Warnings
Changes or modifications to this unit, which are not expressly approved by the party responsible for
regulatory compliance, could void the user's authority to operate the equipment.
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.

Product Selection Guide
The HV ANSI Series is a line of ASCII terminals for use with computers, properly equipped
instruments and industrial machinery.
Standard configuration includes a membrane keypad, twisted nematic liquid crystal display and
modular interface connection, but other configurations are available. A suffix applied to the model
number identifies the configuration as shown below:

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.
