to the OpSw Number. For example, SE8c OpSw 1 is represented as "114.01".
The top-most row above reflects the Board Address configured on the "Basic" sheet.
OpSw value 0 = "T"hrown. OpSw value 1 = "C"losed. Basic
Board ID may be between 1 and 24 if using "Four Aspects per head" mode or may be between 1 and 36 if using "Two aspects per head" mode.
This roster entry will only access the specified SE8C if the Board ID, on the "Basic" sheet, is correct when the
programmer is opened.
If the Board ID has been changed since the programmer was opened, the programmer will attempt to access the
SE8C address which was specified in the Roster entry when the progammer was opened.
After making a change to the Roster entry's Board ID (Active Address) on the "Basic" sheet, save and close the programmer
window and re-open the Roster entry to ensure that the the programmer will use the modified Active Address for accesses
to the device.
Note that BDL16x and PM4x documentation refers to Board Address, while DS64 and SE8C documentation refers to
Board ID. These are equivalent concepts.
Basic SE8c OpSw Settings See the "Basic" sheet for the programmer's limitations with
respect to Board Address. Users should
keep careful records of any such change to each SE8C's configuration. will (by default)
control the signal heads using Switch addresses which cannot be
actuated by the typical LocoNet throttle.
Similarly, when using "Two aspects per head" mode with the SE8C configured
with a Board ID in the range 18 thru 36, the
SE8c will (by default) control the signal heads using
Switch addresses which cannot be actuated by the typical LocoNet
throttle.
If you wish to be able to control SE8C signal heads using a typical
throttle, be sure to use a Board ID number below the
ranges listed above.
This implied switch address configuration may be overriden
by setting OpSw17 to "Closed" and then issuing a turnout
control message on LocoNet.
See Digitrax SE8C documentation for details. equivalent of the DCC track signals. This means that
the SE8C will only react to switch control messages
on the DCC track signal, by default, so the command
station track power must be on. If using the SE8C
on a "Standalone" LocoNet, it will be necessary to configure the
SE8C to take its switch control messages
from "LocoNet messages",
instead of from the "DCC track signal". Dark".
Note that when JMRI is flashing a signal head, there will
be two LocoNet messages for each flash of the lamp. This can be
a significant amount of LocoNet traffic if many signal heads are
flashing.
Additionally, the LocoNet switch commands are passed to
the DCC track signal by the command station. The command
station can only process a limited number of LocoNet
switch control messages. When LocoNet traffic exceeds that
capacity, the command
station will reject the switch control message. This can manifest
as "missed" flashes, "stuck lit"
and "stuck off" signal heads, as well as excessive LocoNet
traffic. This problem may be mitigated by using the
SE8C on a "Standalone LocoNet" and configuring the
SE8C to take switch control messages from "LocoNet messages".Operating Mode
