The PTB-100 Programming Track Booster is a handy tool for anyone who uses DCC! This device facilitates programming as well as gives some comforting feedback during the programming process. You will instantly know if your decoder has received the programming instruction (or not!) by way of indicator lights on the circuit board. So why might you want (or need) a PTB-100? Certain command stations allow you to read a CV during Service Mode programming, which is useful to verify its current setting. Sometimes trouble reading or verifying CVs may be due to the design of the command station and the decoder itself. All decoders communicate back to the command station using what’s called an acknowledgement pulse, which is defined in NMRA RP-9.2.3 as “an increased load on the programming track of at least 60mA for at least 5ms.” Like most decoders, SoundTraxx Digital Sound Decoders generate the acknowledgment pulse by momentarily applying power to the motor. If the decoder is otherwise working properly (i.e., responds properly on the mainline to speed and direction commands), but the command station is having trouble reading CV data from the decoder, it may be due to incompatibilities between the electrical requirements of the sound decoder (which are different from conventional decoders due to the added audio circuitry) and the electrical characteristics of the programming track. In this case, you will need to use a programming track booster, such as the PTB-100. The PTB-100 amplifies the programming track signals to levels that work best with SoundTraxx Sound Decoders. It is easy to install and inexpensive. An advantage to using the PTB-100 is that it also provides short circuit detection and some helpful diagnostics. The PTB-100 is neither needed nor recommended for use with the Zimo MX1 or the Lenz LVZ100.

This product is specifically designed to be used with DC and/or RailPro products. It cannot be used with DCC products. The AR-1 is used to power special configurations of track such as below. Track configuration like below would cause a short circuit if connected without the use of an AR-1. Note that if you follow Rail ’A’ around you will notice that it connects to Rail ‘B’! That is just like putting a piece of metal across Rail ’A’ and Rail ‘B’ which would cause a short circuit and would cause a power supply to shut down. The solution to power special track configurations like below is to add insulation gaps and power the sections with an AR-1. The AR-1 can also be used to isolate small sections of track, limiting the impact of short circuits if derailments occur to just one area of your layout. Features: All Solid State Design Simple Connection with Only 4 Wires No Adjustments Necessary Provides Short Circuit Isolation for a Section of Track Status Indicator Light Fast and Secure Spring Clamp Connecters Fully Enclosed Circuit Board Electronics Size: 4.60 x 3.00 x 1.18 inches Our all solid state design has many advantages over relay based designs. With the relay based designs we tested you could see the locomotive jerk when it crossed the gap at slow speeds. With our AR-1 we saw no visible change in speed at all! Further, compared to relay based designs, solid state units are far less likely to fail, switch many times faster and all without that annoying relay clicking sound.
