INTRODUCTION TO THE RAMSEY URC1:
The Ramsey URC1 is a microprocessor controlled remote control that uses
DTMF for turning voltage levels up and down, pots up and down, timers on
and off, and outputs on and off. It uses the 0-9 digits as well as the * and #
digits of a DTMF encoder, but can also use A-D tones for password
protection. Having two levels of password protection, the master (who owns
or runs the URC) can prevent the user (anyone else) from changing the
states of selected controls, which prevents a user from turning on something
that does not need to be turned on. A six digit display shows the valid codes
that were pressed, and shows errors along the way. The display blanks
during passwords as well as when the unit is finished being accessed to save
on power.
NOTE TO NEWCOMERS: If you are a first time kit builder you may find this
manual easier to understand than you may have expected. Each part in the
kit is checked off as you go, while a detailed description of each part is given.
If you are to follow each step in the manual in order, and practice good
soldering and kit building skills, the kit is next to fail-safe. If a problem does
occur, the manual will lead you through step by step in the troubleshooting
guide until you find the problem and are able to correct it.
