I. General Description
The DiMAX® 203B Digital Booster is based on the same technical specifications as the Di-
MAX® 200Z central station. The DiMAX 203B features 3 discrete output amplifier stages
which deliver 0 Amps permanently ( 2 Amps in peaks) depending on the setting and the
operational mode. An overload protection and a temperature controlled fan are integrated.
The DiMAX 203B Digital Booster provides 3 operational modes: booster, booster with a re-
verse loop function, and booster with a braking function. In addition the DiMAX 203 is inde-
pendant of any digital protocol which makes it usable with NMRA compatible systems or any
other digital system.

Booster

MASSOTH
Connect the power supply cables to the green 2-pole connector with a regular screw driver
and insert the connector into the main power socket on the rear panel of the DiMAX 203B
Digital Booster (as shown in illustration 3). Do not tin the cables! Utilize core cable ends or
twist the cables well before tightening the mounting screws.
3.3 Fuse
The DiMAX® 203B Digital Booster is powered by an external power supply (transformer,
switching power unit, battery). The power supply input is fused with a separate fuse on the
rear panel of the DiMAX® 203B Digital Booster (see illustration 2).
A 0 Amp slow-blow fuse must be used.
3.4 Track Hook Up
The DiMAX® 203B Digital Booster features 3 power outputs which may be connected in par-
allel. For the first test operation connect output # to the track. Parallel operation is explained
later in Chapter 5. .
Connect your track power cable to the black 2-pole terminal. Mind the correct polarity. Do not
tin the cables! Utilize core cable ends or twist the cables well before tightening the mounting
screws.

3.5 Hook up of Control Components
The DiMAX® 203B Digital Booster features two terminals on the front panel. These terminals
may be utilized to connect a Central Navigator (see note page 2), DiMAX bus components as
e.g. feedback module, train detector, or the DiMAX transducer to the DiMAX® 203B Digital
Booster. The DiMAX transducer will enable you to use LGB MTS II components with the Di-
MAX system.
The Master terminal is reserved for the Central-Navigator (see note page 2) only!
The Slave terminal may be used as a regular control bus terminal for DiMAX components.
These terminals may only be used for the operation of a Central-Navigator (see note page
2) in conjunction with DiMAX components!
A regular Navigator does not work, when connected to this jack!
3.6 Hook Up with a DiMAX®, LGB® o er Lenz® central station (or compatible)
The rear panel (Illustr. 2) provides two options for connecting bus components.
The DiMAX® 203 Booster may be connected to a Lenz® central station (or compatible) with
the 3-pole Lenz® CDE jack.

See the manual of your central station for the correct wiring!
The DiMAX® 203 Booster connects to a DiMAX® or LGB® central station (MTS II or III) via
the 4-pole booster bus terminal. Utilize the booster interface cable to hook up the booster to
the central station.
