To set timer1 on for 35 hours 12seconds, and off fore 10mS: 
*8101*00120035
Hook up some LEDs as shown with series resistors to the timer outputs, and 
then experiment a bit to see how this method works. Have patience as these 
codes take a little time to get used to. 
 
 
 
 
 
 
 
For the master user to exclude devices from the user: 
 
To exclude: 
 
*X[00-18]1
 
To include: 
 
*X[00-18]0
 
The access number is found on the chart with the pinouts of CON1. Since 
there is only 19 devices (0-18), any number over 18 is rejected and the 
command is aborted. 
The URC1 replies with a short then long tone to indicate “A” for acknowledge. 
 
Example to turn timer 2 off from the user: 
 
*9181
 
Where 9 is the control code, 18 is the device number, and 1 disables the 
device from the user changing it. Notice of course that you must be entered as 
a master user to change these settings. Entering a 1 disables, and a 0 
enables.
