Step-by-step Construction File:Http://www.christmasinshirley.com/wiki/index.php?title=File:Ren-w layout.GIF

1. Solder 2mm female headers at locations H1, H2, H3, H4 or:

TX only: only H1, H2 are required

RX only: only H3, H4 are required

E-mode repeater: only H1, H2 are required.

Normal repeater mode: all four headers required

2. Solder the 16-pin DIP socket into the MAX232 location (skip if no socket is used and the MAX232 is to be soldered directly to the Ren-W board) .

3. Solder capacitors C1, C2. No polarity is required.

4. Solder electrolytic capacitor C3. Note the polarity: the + side into the square pad (top) closer to jack J2.

5. Solder 2-pin headers JP1, JP2, JP3, JP4, JP5, JP6. (Note: JP1 and JP2 are optional.)

6. Solder RJ45 jacks J1, J2

TX only: only J1 is required

RX only: only J2 is required

Normal repeater and E-mode repeater: both J1 and J2 are required

7. Solder zener diode D1. Note the polarity – the band on the diode must be facing up, next to header JP6.

8. Solder resistors R1 (orange-orange-black) and R2 (brown-black-red). R2 is only required if the optional power LED (D2) is used. No polarity concerns.

9. Solder the optional power LED at position D2. Note the polarity – the flat side/cathode/shorter lead faces to the mounting hole immediately to the right of D2.

10. Solder the 3.3v voltage regulator U1. The heat sink side faces toward JP2 (top). The need for an additional heat sink is highly unlikely as the supply voltage is only 5vdc.

11. Install the MAX232 and XBee module(s) in their respective sockets. Note the position of pin 1.

12. Install optional jumper shunts at JP5 and JP6 if necessary (see documentation).
