S-CAB Radio Documents

S-CAB Quick Start Guide
With these 3 pages and an hour or two at the work-bench, you will have S-CAB radio tested with a decoder and ready for your first installation.
S-CAB Throttle User Guide
Just about everything you need to know about S-CAB Throttle in 13 pages. Explains the throttle's basic design and, more importantly, the logic behind its controls. With experience and knowledge of how S-CAB works, you won’t need tedious cook-book instructions to become an expert user.
Tweaking Decoder performance
If decoder and motor characteristics are well matched and loco control performs to your satisfaction, don’t tweak. If loco performed nicely before decoder installation and you are not satisfied with control after installation, some tweaking will help.

S-CAB Radio Receiver

A radio-ready decoder is assembled by combining the radio receiver (current model is LXR v2.1a) with the decoder requested by a user.
Although LXR is not available as a separate item), the following dimensional information may be helpful.
Since sizes are similar, LXR and decoder are generally packaged back-to-back to create a compact package. However, receiver and decoder are only connected by 3 wires and can be separated when specifically ordered this way.
The antenna can be separated from the receiver only by using coax cable, which is stiff and difficult to handle in HO sized spaces. For very short range radio reception (5 to 8 feet), the antenna can be replaced by a 3 inch length of wire.
Since metal surfaces reflect radio transmission, antennas don't perform well if fully enclosed in metal containers (a brass loco, for example). Vertically mounted in a tender coal load works well.

BPS Test
Please plug in battery and perform this BPS test before continuing installation. This test proves BPS is working correctly.
Battery Shutdown using TSU-1000
With some decoders, a DCC command can be used to turn off the BPS battery and prevent slow discharge when a loco is not in use. This document describes use of a Tsunami TSU-1000 command to shut down battery
