This project is my attempt to deal with the fact that no matter how many cables and adapters I collect I never seem to have the right cable/adapter.
A tee connector is a connector with 3 connections, a Tea connector is built in a Twinings Tea case and has 8 connectors, two of each common RS232. So it is a Octopus Tea Connector.
Step 1: Materials
A Twinings Tea Can: I like Prince of Wales Tea, seems to stimulate the RS232 signals.
Colored Wire, stranded fairly fine. Colored wire makes keeping track of the connections much easier.
DPDT Switch. You need this if you are using a 3 wire connection and want to have a null modem option.
Wire nuts or heat shrink tubing. For making or insulating the connections. Heat Shrink Tubing
Misc small nuts and bolts.
Step 2: Tools
Soldering Iron, wire cutters, and wire strippers.
Screwdriver, needle nose pliers......
Step 3: Mark It Up.
Step 4: Cut It Out.
Step 5: Wire It Up.
Cut 8 wires of each color, I used about 8 inch long wires, you could probably use shorter one. Tin the wire ends and the connector ends. I just lay the wire on the connector and reheat the solder. Not the fanciest or strongest connection around, but seems ok. If you like insulation insulate it now. Heat shrink tubing can make a really neat job of it. I actually used some insulation stripped from a phone cable, seemed ok.
I connected the 4 connectors for the lower layer together, with an extra wire for the receive and transmit and ground, these will connect to the upper level. At this point you may appreciated the fact that the wires are color coded. I used a wire nut for some and when I ran out of them just twisted them together and soldered, then finished of with heat shrink tubing. Then I put the connectors in the lower level of the tin. Half way done!
Repeat for the upper layer of connectors, but tie the extra wires from the lower level in this connects the two layers together. ( if you use the null modem option below, do not connect the layers together, except for the ground, put an extra set of wires on the top layer and run the receive and transmit to the double pole double throw switch together. All the way done!!
