Version 2.5 features

Version 2.5 starts with number keys (small buttons) assigned to function control. No need to press ‘FG1’.
In control mode, the ‘ALL’ button initiates the following 3 commands:
  • ‘ALL’, ‘HALT’      All loco emergency stop
  • ‘ALL’, ‘0’           All loco reset (zero speed, forward direction)
  • ‘ALL’, ‘5’           All batteries off
​​​In CV mode, the ‘ALL’ button initiates global addressing, which must be used to program SoundTraxx decoder CVs
CVs 128 and 120 only work for SoundTraxx decoders and their use requires the following procedure:
  1. Be sure to turn off all decoders except the one to be programmed
  2. Switch the throttle to CV mode. Display will show “C”
  3. Press ‘ALL’. Display will show “CA”.
  4. To adjust sound volume, press ‘FG1(CV#)’ multiple times as display cycles      through CVs; C1,  C2,  C3,  C4,  C5,  29, until “2.8” is displayed.
  5. Press ‘FG2(CV=)’ and display will show “70”. This is a prompt suggesting 70% of maximum sound volume.
  6. ​Press ‘Enter/Send’ if 70% is acceptable. If not, use number keys to enter an alternative (for example, ‘5’,‘0’ to select 50%) before pressing ‘Enter/Send’. Display will show “50”, but actual value transmitted to decoder will be 50% of 255.
CV120 is horn/whistle select. SoundTraxx decoders include a selection of sound files and experimenting with different horn/whistle sounds is an interesting way to add some uniqueness to a loco roster. The procedure is similar to CV128. Press ‘FG1(CV#)’ repeatedly until display shows “2.0”, Then press ‘FG2(CV=)’ and enter a number from SoundTraxx list. Default choice is zero.
‘ALL’, ‘5’  All batteries off. This command has been added as a convenience for operators with a large roster of battery powered locos. However, it only works when a decoder function output has been wired to the BPS battery-off terminal (which is default wiring for an S-CAB system). ‘ALL’ addresses the message to all locos and every active decoder will respond if the message is repeated a few times (3 is usually enough). Once pressed, ‘ALL’ is latched, so ‘5’ button repeats the command.

Planning

The primary objective is to install battery power in a locomotive.
