(we're not kidding - we get a lot of e-mails with questions that are already addressed in the Frequently Asked Questions web page)

After soldering all components for TEMP05, carefully insert all IC’s in their sockets, observing polarity while doing so. Connect a terminal (or PC running your favorite terminal emulation software) to connector P1. Now connect the power and observe the following.

1. The LED should initially flash red and then steady out to a blinking green.
2. The PC or terminal should display a start-up message.

If the LED is flashing red instead of green, then you have connected the LED backwards. If the LED is not on, the software is not running, the power is not on, or there is a connection problem somewhere. Double-check for solder bridges between PCB pads.

OK, you should be up and running now. If you did not install the optional DS18S20 connect one now (turn the power off first!) to connector J2 (J6 if you have installed the optional RJ-12 connector). Only 2 pins need be connected, however a connection is required between the VDD and GND pins of the DS18S20 if you are using parasitic power. Refer to the spec sheet for the device you are using to determine how to identify the DQ, VDD and ground pins, or see Figure 1.  If you wish to provide local power to your sensors, use the 3rd terminal of J2 provided for that purpose.  J6 also includes a source of +5V.

Power back up, if necessary, and then configure the unit for the devices you have connected. I recommend that you use the ERA command to erase the EEPROM first.  This will remove any previous information that may have been stored in the EEPROM.  Next use the INI command to search for any DS18S20's connected to the 1-Wire bus.  If you get any error messages, it is most likely a result of a bad connection to the DS18S20(s). Verify them.  Typically, a "OW bus error" message indicates that a sensor has been installed in reverse, or that there is a short on the bus.

Now program the configuration by using the SET command. Just type SET and the program will prompt you for the required settings; logging interval, Relay Timer interval, F/C display and wind direction reverse setting.

To verify you are working, you can use the TMP command to perform an immediate sensor reading. The output of the TMP command should look like Figure 2 below (the exact output will depend on what type and how many sensors you have installed).
