Important ordering information: There is no minimum order, but in order to provide parts for as many people as possible, there is a maximum order amount of $100. Orders that exceed that limit will be automatically refunded. Also, as of March 2011, international shipping is now available. Shipments to the United States, Canada, or Mexico are trackable and insured. Shipments to all other countries are not trackable, and are also not insured.

Assembling the Tex PC board is very simple. As usual, working from the smallest to the largest parts will facilitate keeping the parts in place while soldering. The above Parts List reflects this approach, and you can simply install the parts in order from the top to the bottom of the Parts List.
The following procedures should be observed as you populate the board:
- Thorougly clean the board before soldering. A "Scoth-Bright" plastic abrasive pad works well for this purpose.
- Solder the 6-pin header in place as shown in the above photos.
- Solder resaistor R3 in place as shown in the above photos.
- Resistors R1 and R2, and capacitor C1 are all installed underneath the machine-pin socket. The best way to do that is to insert those three parts, but before you solder them in place, test-fit the 8-pin socket to be sure that it can be fully inserted into the board. (Be sure to observe its correct polarity.) You may need to bend one or two of the parts to get everything to fit correctly. You can also use a sharp hobby knife to shave a little plastic from from the socket where necessary. When the socket is fully seated on the board, leave it inserted and solder R1, R2, C1, and the socket in place.
- The IR-LED can be mounted on the PC board in three different ways:
- If you fully insert it into the PC board from the top (observing the correct polarity), the LED will point forward, which is a suitable orientation for breadboard circuits.
- If you fully insert it into the PC board from the bottom (observing the correct polarity), the LED will point backward, which is also a suitable orientation for breadboard circuits.
- If you want to use the Tex board in a hand-held transmitter circuit, you can insert the LED into the PC board from the top(observing the correct polarity) and, before soldering it in place, bend its leads 90 degrees so that the LED points directly up. That way, when the board is held horizontally (as it would be in a remote control), the LED will point forward. With this configuration, you may also want to replace the right-angle header with a straight one, so that the Tex board will be parallel to your main hand-held project board.
In order to test your complete Tex PC board, you will either need a functional Rex board or a breadboard IR receiving circuit. If you have any problems getting your Tex PC board to function properly, email me at Ron@JRHackett.net and I will do what I can to help.
