Using the DB210/220 as an auto reversing booster
The DB210/220 can be configured as an auto reversing booster. The DB220 dual
booster can be configured so that 1 or both of it’s boosters are configured for
auto reversing. With the DB210 setting the switch to ON will cause the booster
to be auto reversing. With the DB220 dual booster you have the option of either
configuring either one or both of the boosters to be auto reversing. Set the
AUTO REV switch to 1 and the R1A and R1B track outputs will be auto revers-
ing. Set the AUTO REV switch to 1&2 and both R1 and R2 track outputs will be
auto reversing.
In order for auto reversing to work a reference booster must be used. This can
be either your command station or another booster. In the case of the DB220
when only R1A and R1B output are set for auto reversing the R2A and R2B
outputs can be used as the reference booster. Visit www.digitrax.com for more
information on auto reversing.
Use the figure 2 as a guide to configuring the DB210/220 for Reverse Loops.
Note that the DB210/220 connections to the track are NOT directly connected
to the track of any other booster or command station on your layout. In every
case Digitrax requires double gapped isolation for each booster and command
station.
