Description
Industrial Design, Inc. currently manufacturers and sells three different Serial touch Screen Controllers:

TS-101
PC/104-16 based Serial Touch Screen Controller Add-On Board with its own integrated Extra Serial Port

TS-109
Stand-alone Serial Touch Screen Controller Board with an RS-232, DB-9, Female Serial Interface and external Power Supply for use with an existing standard RS-232 Serial Port.

TS-110
Stand-alone Serial Touch Screen Controller Board with an RS-232, 10-pin Header, Male Serial Interface with Data Cable-supplied power for use with an RS-232 10-pin Header/Power Serial Port.

Product Overview

The TS-101 is a PC/104 16-bit Add-On Board containing both DynaPro's SC3 Serial Touch Screen Controller and an integrated, on-board Serial Port for direct interface of this controller to a PC/104 capable computer system without the use of any of the existing serial ports in the system. The integrated Serial Interface (COM Port) can be set at any 8-bit boundary I/O address between 000H and 7FFH and can use any of the free Interrupts in the system.

The TS-109 and the TS-110 both contain the same SC3 Serial Touch Screen Controller as the TS-101, but the controllers connect to the system via one of the system's existing serial ports. The two controllers are, essentially, the same, but the TS-109 has a "normal" DB-9, Female Serial Interface connector for use with a "normal" Serial Port and also needs between +5V and +12V power supplied from an external source, whereas the TS-110 has a 10-pin, Male Serial Interface Header for flat-ribbon based serial connection through which the power may also be supplied. The TS-110 - was built for direct-connect use, and provides both the serial data and the power supply in the same 10-pin ribbon cable.

All of these Serial Touch Screen Controllers allow the use of a normal, 4-wire, 5-wire or 8-wire Resistive Touch Screen instead of, for instance, a Mouse. The controllers are delivered complete with User Manual and the latest version of DynaPro's Touch Screen Driver Software for any of the Operating Systems shown below. These drivers emulate a standard Mouse Input, and can, therefore be used with any software requiring Mouse based input.

The Touch Screen add-on glass is easily mounted in front of an LCD Panel (please specify screen size!) or a CRT Screen, and is integrated into the system via one of these Serial Touch Screen Controllers.

The Touch Screen Software Drivers make the Touch Screen act like a normal Mouse input. These Drivers are available for several different operating systems, like MS-DOS, WINDOWS 3.1x, WINDOWS FOR WORKGROUPS, WINDOWS 95/98, WINDOWS NT or UNIX (please specify operating system when ordering)!

The use of Touch Panels is especially GREAT for use in both industrial and/or military environments, in environments with heavy moisture, dust, contamination, mechanical shock or vibrations. In addition, a typical use is in 'INFORMATION KIOSKS', factory floor input and information devices, or other public or industrial information retrieval systems.

How to install the module under WINDOWS 95/98

On the COM Port you are going to use to connect the Serial Touch Screen Controller to the system:

1. Make sure the COM Port is installed and active.

2. Note the I/O Address and the Interrupt Number for the COM Port you are going to use.

Make sure the PC's power is OFF. Now connect the Serial Touch Screen Controller to the desired COM Port on the Computer:

1. For the TS-109, connect it to a DB-9 Male connector of an available COM Port. Also connect the Power supply to the Controller (it uses +5V to +12V)

2. For the TS-110, connect it to the COM1 Port on INSIDE's PanelLink receiver Board, or to COM2 Port on INSIDE's Single-Board Computer with the supplied Data-Power Cable (See cable drawing below). Note that any standard pin-out 2*5 pin male header COM Port connector where Pin 10 carries +5V to +12V can be used.

3. Connect the Touch Screen's connecting wire to the Serial Touch Screen Controller Screen Input connector. Note that this connector is keyed to prevent incorrect insertion)

Switch the PC ON and allow Windows 95/98 to load. If it is not already installed, or if Windows 95/98 does NOT discover a newly installed serial port automatically when it loads, then install the new serial port into Windows (Note: you can skip this step if the port was already installed):

1. Enter Control Panel (Start button, Settings, Control Panel, or: My Computer - Control Panel Icon)

2. Double-click the Add New Hardware Icon

3. Click Next

4. Select No and click Next

5. Select Ports (COM & LPT) and click Next

10. Click Calibration

11. Click Calibrate

12. Follow the screen prompts (upper left, lower right and then 3/4 up+right)

13. Click or touch OK

14. Click or touch Exit

Your TS-109 or TS-110 Serial Touch Screen Controller and Touch Screen are now ready for use!

Trouble Shooting:

The most typical error is incorrect setting of Input/Output Address and/or Interrupt Number for the COM Port whereto the Serial touch Screen Controller is connected. These should be checked both in the Systems Settings and in the Touch Screen Configuration Settings.

To check System Settings, go via: Control Panel, System, Device Manager, Ports (COM & LPT), Communications Port (COMx), Properties, Resources, Input/Output Address and Interrupt Number.

To check Touch Screen Settings, go via: Touch Screen Configuration, Interface, Interrupt Number and Input/Output address (while you are at it, check the Advanced setting for correct number of wires)

If you alter any of these settings, you will have to re-start windows before the Touch Screen will work and/or can be calibrated.

Note also: You must Calibrate the Touch Screen before you can use it, as shown above.

Enclosed here for reference, are the typical pin-outs and signals of a normal 2*5 pin Serial COM Port Header. Notice that these are the same signals, and map 1-to-1 with the signals, in the normal DB-9 Female COM Port connector, except for pin 10 (+5 to 12V) which is NOT present in the DB-9 connector!

Combined Serial Data and Power Flat-Ribbon Interface Cable for TS-110

This note shows how to make the cable that is mounted between the TS-110 2*5 pin male shrouded header and a typical 2*5 pin male shrouded COM Port header on a typical SBC or other board.

Cut a 10-wire flat ribbon cable to 18" (or any other length that the customer wanted) Mount a 2*5 pin female IDC Connector on the one end.
Slide a second connector over the other end, but leave it non-attached, to allow the customer to mount this connector at the length he wants and cut the cable. That's it. Pack it up and ship it. You're done!

Customer: Remember to press the top of connector 2 in place before use!
