POWER SUPPLY REQUIREMENTS
The ADC-16 may be powered from any DC voltage source which will supply 200 ma within a voltage range of 9 to 14
volts. The recommend power supply for use with a single ADC-16 card is the PS-GP-1 (wall transformer supply).
IMPORTANT: Use caution when connecting the power source, reversed polarity may cause damage. The heat
dissipation of the 7805 regulator on the ADC-16 will be greatly reduced with a 9 volt power source. The PS-9VDC-500
or PS-9VDC-1000 wall transformer power supplies may be used to power both the ADC-16 and expansion card(s)
without the need for additional regulators. Please note that the PS-12VDC-500 and PS-12VDC-1000 are unregulated
supplies and may produce voltages as high as 18 volts (see pages 7 & 8).
POWER SUPPLY FUSING: A 500 milliamp (.5 amp) in-line fuse should be installed in series with the (+) power supply
lead to protect the power supply and the ADC-16 from damage (or order with the /T option).
SET-UP AND TESTING
Upon receiving your ADC-16, you should connect and test the operation of the hardware to verify proper operation.
Please set-up and test the ADC-16 as follows (Windows computers):
(1) Plug the serial cable into COM 1 of your computer and connect the other end to the terminal block on the ADC-16
(as shown on page 2). If you did not order a serial cable, a cable may be fabricated by soldering the wires to the proper
connector as shown on the following pages. Care should be taken to prevent any static discharge on the ADC-16 by
touching a metal ground before handling the ADC-16 and associated circuits. Use caution not to set the ADC-16 or
associated hardware on a metal surface or damage could result.
(2) Connect the power supply (part # PS-GP-1) to the six position terminal block at the bottom of the ADC-16. Be sure
to observe the (+) and (-) connections on the ADC-16 (reversed polarity may cause damage). Connect the RTC-16
terminal block to ports #1 and #2 on the ADC-16. The ribbon cables for the RTC-16 should be routed underneath the
ADC-16 so that the RCT-16 is on the right side of the ADC-16.
(3) The ADC-16 is set to 9,600 baud at the factory. This is the proper setting for use with the test software which is
provided on CD with your order. NOTE: If any of the analog ports have been configured for temperature input, skip
this section and complete the set-up and testing requirements which are described in the TE-8 technical reference.
If your operating systems is Windows 95, 98, ME, or Windows 2000 you must use the Universal App on the installation
CD for testing your ADC-16. Windows XP, Vista, Windows 7, Windows 8 and up users may install the .Net App* which
uses the Microsoft .Net Framework. Click the install App button on the installation CD startup window or run setup.exe
in the folder Windows Data Acquisition Program. If prompted about an older file, keep your newer file. Once installed,
run the ADC-16 program. The program defaults to Com 1. Other Com ports may be selected if required.
*Please note that the Microsoft .Net Framework must be installed on your system. If the .Net Framework is not installed
on your computer, the ADC-16 installation program will attempt to download and install the .Net Framework from the
Microsoft web site through your internet connection. This may take 5 minutes or longer. In order for the .Net
Framework to install correctly, your computer must be up to date with Windows update (Windows XP must have
service pack 3 installed). This is especially important with Windows XP and Vista. You may update your computer by
clicking on the start button, All Programs, Windows Update and clicking on "Check for Updates".
Your screen should show a row of eight or sixteen numbers. The top 8 numbers represent the analog inputs for port #1
and the bottom 8 numbers represent the analog inputs for port #2. The numbers may be fluctuating as a result of noise
on the analog inputs (this is normal).
(4) Test each analog input by connecting each input (one at a time) to the reference (-) terminal on the RCT-8 or RCT-
16 (see page 4). Your screen should show a "0" for that input. After this is completed, connect each input (one at a
time) to the reference (+). Your screen should show a "255" for 8 bit inputs or "1023" for 10 bit inputs for each input. If

WARRANTY AND CARE OF THE ADC-16
The ADC-16 Analog to Digital Converter is warranted against factory defects for a period of 90 days from the date of
purchase. The ADC-16 has proven to be extremely reliable in actual operation during field tests. We recommend that
the ADC-16 and associated hardware be installed in a suitable enclosure (4 mounting holes are provided on the
circuit board) and that reasonable precautions be taken to protect the circuit from static discharge. The most likely
damage to occur is that caused by lightning discharge through the power supply or serial I/O lines. The best way to
prevent this type of damage is to install a Power Protector (Part # SP-120 or Surgebuster #120K15A) in the electrical
outlet which supplies power to the hardware. Shielding the analog input lines will provide additional protection. If
further protection is desired, install a TransZorb across the power input to the interface card (part #SP-12K) and to
the RS-232 lines (part #SP-232K).
