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 9.5 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.
3. Not available on battery units
Example
The configuration number for a PDS with a vacuum flourescent display, a 45-key elastomeric keypad, a
RS-232 interface, a 7.5 to 12 VDc linear power suppy in a black case would be:
PDSVFD45EKR2-2-BK

Document 15803(1.0.0.0) vii
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 PDS 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
PDS45R2 Base Unit with 45-key Keypad & RS-232 55 mA
PDS45R2 Base Unit with 45-key Keypad & RS-422 65 mA
Current Draw for Options
N Supertwist Display Add 10 mA
NL Supertwist LED Backlight Add 185 mA
NEL/TEL Supertwist Backlit Display Add 70 mA
VFD/TVFD Vacuum Fluorescent Display Add 300 mA
KL Backlit Keypad Add 80 mA
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—PDSNELR2:
RS-232 Option 55 mA
Supertwist Backlit Display 70 mA
Calculated Total Current 125 mA
Example 2—PDSNLKLR2:
RS-232 Option 55 mA
Supertwist LED Backlit Display 185 mA
Backlit Keypad 80 mA
Calculated Total Current 320 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 Voltage
range.
3. Look at the corresponding Maximum Input Voltage Allowed where the intersection
occurs to find the maximum useable voltage for your terminal configuration.

Maximum Input Voltage Allowed
Using Example 1 and the chart above, the 125 mA drawn by the PDSNELR2
intersects with 13 volts. If the maximum supply voltage to the terminal is greater
than 13 VDC, it requires a -H power supply configuration.
Using Example 2 and the chart above, the 320 mA drawn by the PDSNLKLR2
intersects with 8.13 volts. If the maximum supply voltage to the terminal is greater
than 8.13 VDC, it requires a -H power supply configuration.
To clarify, if your system is supplying 12 VDC, the power is acceptable for the
PDSNELR2 (Example 1), but not for the PDSNLKLR2 (Example 2). Applying 12 VDC
to the PDSNLKLR2 (Example 2) will damage it.

About Two Technologies
Two Technologies has been producing rugged hand held and panel mount terminals and
computers for over fifteen years. By implementing state of the art design and manufacturing
techniques, we revolutionized hand held terminals and computers inside and out. Today, Two
Technologies offers over a dozen cost-effective solutions serving virtually every market.
About the PDS
The PDS is a rugged, full featured programmable hand held terminal that is ideally suited to
a variety of applications where a level of complexity above that found in simple ASCII
terminals is required.
You can program the PDS using Assembly, C or 2BASIC programming languages. With its
comprehensive Applications Program Interface (API), you can access a variety of services
provided by the operating system, from simple display manipulation to high-level
operations.
PDS Features
Two Technologies offers PDS terminals with the following features. You can find additional
information regarding specifications in Appendix A.
Power
The PDS is available as a line-powered or battery-powered unit. Line-powered units use a
7.5-12 VDC linear regulator. If needed (depending on current draw), a 5 VDC (±5%)
transformer and optional 9.5-28 VDC switching regulator are also available.
Battery-powered PDS terminals come equipped with a rechargeable Nickel Metal Hydride
(NiMH) battery that has exceptional charge life without the “charge memory” characteristic
of conventional nickel cadmium batteries. . Battery-powered terminals can also operate on six
AA alkaline batteries.
Memory
The PDS features 448 K-bytes of Flash EEPROM, 512 K-bytes of battery-backed static RAM
Display
PDS 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,
extended temperature and vacuum fluorescent displays, as well as optional character sets,
such as Latin 1 or European are also available.

Keypad
Securely framed and clamped into place, the keypad surface provides excellent splash
resistance and prevents curling or peeling of the keypad overlay. Keypad layouts include 45,
30, and 20 keys available with standard or custom graphics and 32 and 15 keys available with
custom graphics. Keypads can be made from your choice of elastomeric or membrane
material.
Interface Options
Interface options for PDS terminals include RS-232, RS-422 or CMOS/TTL protocols.
Communication (up to 19,200 bps) with a host device is through a modular 6-pin connector.
Emergency Stop Switch
An emergency stop switch is optionally available. The stop switch has a push-off, turn-reset
motion. A fully depressed E-Stop opens all the circuits and can bring the machinery to a
complete halt.
Wireless Radio
With the optional RF Module, you can transfer a standard asynchronous serial data stream
over-the-air between devices. No configuration is required. It uses standard AT commands
for changing parameters. Simply output serial data from the RS-232 port into the RF module
to send FCC & ETSI approved, frequency hopping spread spectrum data.
Durability
Like all Two Technologies' products, the PDS is remarkably rugged. The case consists of
Cycolac ABS, one of the most durable, chemical-resistant materials available on the market
today.

Operation
10
Battery-Powered Units
Battery-powered PDS terminals come equipped with a rechargeable Nickel Metal Hydride
(NiMH) battery that has exceptional charge life without the “charge memory” characteristic
of conventional nickel cadmium batteries. Depending on configuration and use, operating
time on a full charge can last up to 24 hours. Battery-powered terminals can also operate on
six AA alkaline batteries
.To turn on a battery-powered unit, press any function key. The terminal should turn on and
a blinking cursor should appear on the display.
To turn off the unit, press the CTRL and F5 keys.
Power Saver
To conserve power, a built-in power saver will turn off the terminal after ten minutes of
inactivity. After eight minutes, the terminal will emit short warning beeps spaced twenty
seconds apart. Twenty seconds after the fifth beep, the terminal will shut down. Any key
press or character received by the terminal will reset the power-saver timer.
Recharging the Unit
By default, when the battery power level is low, the message “LOW BATTERY” will flash on
the last line of the display approximately every seven seconds. The message remains
displayed for one second, and then restores to its previous condition.
The recharging time required for a full charge depends on the initial state of the battery. With
the terminal off, this time should not exceed eight hours. Partially discharged batteries or
extended periods with the charger left connected will not adversely affect battery life or per-
formance.
Because the internal battery charger senses several conditions, including temperature, you
should charge the unit away from any known or potential heat sources. Units exposed to
temperatures in excess of 90 degrees Fahrenheit during the charge cycle may experience
incomplete charging and reduced operating time per charge.
To recharge the Nickel Metal Hydride (NiMH) battery pack, plug the Two Technologies’
power supply/battery charger (Part # 13779) into the PCAT adapter and then plug the power
supply/battery charger into a 120 VAC 60 Hz power outlet.
