4.2.11 CV Inquiry with Verbal Feedback in Ops Mode (CV64)
63
To inquire about the current value of any non-indexed CV using Verbal Feedback in Ops Mode:
•
Set CV64 to the number of the CV you wish to query.
•
Hear the verbal message
CV n equals m
where
n
is the CV number and
m
is the value of that CV.
If the CV is indexed (e.g., CVn.PI.SI where n is the CV number, PI is the Primary Index, and SI is the secondary
index, if any),
•
First set CV49 to PI
•
Next set CV50 to SI (if there is a secondary index)
•
Then set CV64 to n
•
You will hear a verbal report similar to that in the example below
For example, if you want to inquire about the Bell Volume, which is CV52.8 (see
Table 8
), set CV49 to 8 and then set
CV64 to 52. You will hear,
CV five two point eight equals ‘Y’
(where ‘Y’ is the current volume setting).
Note
:
If you enter either ‘17’ or ‘18’ into CV64, you will hear the full Long Address ID number spoken out.
4.2.12 Enable/Disable Horn-Triggered-Doppler Shift (CV51.2)
•
Set CV49 to 2.
•
Set CV51 to 0 to disable Horn-Triggered-Doppler; set CV51 to
1 to enable.
4.2.13 Enable/Disable Automatic Horn Warning Signals (CV51.20) – Versions 8 and 9 only
You can use CV51.20 to enable (or disable) the following automatic horn warning signals that can be generated by
the Quantum Titan sound-decoder. This scenario imitates the actions required of a prototype
locomotive engineer
when he starts and stops his locomotive
.
•
Two short Horn blasts when the locomotive first starts to move in FWD,
•
Three short Horn blasts when the locomotive first starts to move in REV,
•
One short Horn blast when the locomotive comes to a stop.
To enable or disable these Horn warning signals, perform the following steps:
•
Set CV49 to 20.
•
Set CV51 to 0 to disable all Horn Warning Signals, or set CV51 to
17 to enable all three of the Horn Warning
Signals listed above.
If you want to enable a different horn warning scenario from those specified above, please refer to the definition of
CV51.20 in the
NMRA DCC Reference Manual for QSI Quantum 3, 2, and 1 Equipped Locomotives
[3]
.
If you wish to
modify the timing, duration, and/or number of Horn blasts in a Horn Warning Signal scenario, please refer to the
definition of CV120.PI.SI
64
in this same reference manual.
4.2.14 Speed-Matching
if you wish to consist two locomotives together, in order to avoid mechanical damage to one or both locomotives in the
consist, it is important that the velocities of the two locomotives closely match each other over the entire range of
speeds at which they operate.
If you are speed-matching a locomotive that has a Quantum or Quantum Titan sound-decoder to another locomotive
whose decoder does
not
have Regulated Throttle Control (aka, BEMF) you almost always need to turn off BEMF in
the Quantum-or-Quantum-Titan-equipped locomotive (first set CV49 = 4; then set CV56 = 0; see Section 4.2.5)
before trying to speed-match. You may also need to reduce or eliminate any momentum that is specified in CV3 and
CV4.
The Quantum or Quantum Titan
sound-decoder in your Atlas Gold Series locomotive provides two ways to match
locomotive speeds, which will be explained in the next two subsections.
63
This option is not affected by CV62 (Disable/Enable Verbal Announcements).
64
PI
stands for
Primary Index
;
SI
stands for
Secondary Index
. Refer to Section 4.2.2 of this document or to Sections 5.1 to 5.3 in the QSI DCC
Reference Manual [3] (pages 93 to 98 in Version 5.1.0) for an explanation of the Indexed CVs used in QSI sound-decoders.
