Decoders are programmed when the command station sends programming information to them through the rails This information is sent as a broadcast message to any decoder that is listening This means that you could reprogram all the locos on the track with one keystroke To prevent this it is useful to add an isolated programming track as described in Section 5 2 Set Decoder Address Setthe rotary selectors to the desired address 01 98 2 Press the ADR button to select and send that address to the decoder The decoder will now answer to the new address Set Configuration Variables CV s 1 Set the rotary selectors to the CV number that you wish to set then press the F1 CV button This tells the decoder which CV you wish to change 2 Once you have selected the CV you wish to change use the rotary selectors to set the value of that CV Now press VL to select and send that value for the CV previously selected To change additional Configuration Variables repeat steps 1 and 2 as many times as necessary 3 resume normal operation press RUN STOP and PROG buttons simultaneously to take the UT2 out of Programming Mode 4 Press RUN STOP and ON to turn track power back on Table II Most Commonly Used CV s Ad 1 Loco Address 0 98 decimal Start Voltage Vstart 0 99 decimal 06 Mid point Voltage Vmid 0 99 decimal 29 Table III Configuration Register Values The
