CV Definitions:

              OpSws Short Address gt 0 <html>The "CV" column in the table above shows "OpSw" numbers, where the value "114." is pre-pended <p>to the OpSw Number. For example, SE8c OpSw 1 is represented as "114.01". <p><p>The top-most row above reflects the Board Address configured on the "Basic" sheet. <p><p>OpSw value 0 = "T"hrown. OpSw value 1 = "C"losed. </html> Basic <html><p> 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. <p> <p>This roster entry will only access the specified SE8C if the Board ID, on the "Basic" sheet, is correct when the <p>programmer is opened. <p> <p>If the Board ID has been changed since the programmer was opened, the programmer will attempt to access the <p>SE8C address which was specified in the Roster entry when the progammer was opened. <p> <p>After making a change to the Roster entry's Board ID (Active Address) on the "Basic" sheet, save and close the programmer <p>window and re-open the Roster entry to ensure that the the programmer will use the modified Active Address for accesses <p>to the device. <p>Note that BDL16x and PM4x documentation refers to Board Address, while DS64 and SE8C documentation refers to <p>Board ID. These are equivalent concepts. </html> Basic SE8c OpSw Settings <html><span style="color: black;"><h2><strong>Operating Mode</strong></h2></html> <html><span style="color: black;"><h2><strong>Signal Head Characteristics</strong></h2></html> <html><span style="color: black;"><h2><strong>LocoNet Characteristics</strong></h2></html> <html><span style="color: black;"><h2><strong>Inputs Characteristics</strong></h2></html> <html><span style="color: black;"><h2><strong>Outputs Characteristics</strong></h2></html> Notes <html><span style="color: black;"> <h2><strong>Notes on SE8C Roster Entries and Programming </strong></h2></html> <html></strong><ul> <li>The SE8C <em>must</em> be in its normal operating mode in order to respond to this Roster entry's read and write operations.</li> <li> <p>See the "Basic" sheet for the programmer's limitations with respect to Board Address.</li> <li>This Roster entry is neither able to query nor change the SE8C to determine the addresses which control the signals. <p>Users should keep careful records of any such change to each SE8C's configuration.</li> <li>When using "Four aspects per head" mode with the SE8C configured with a Board ID in the range 13 thru 24 the SE8c <p>will (by default) control the signal heads using Switch addresses which cannot be actuated by the typical LocoNet throttle. <p>Similarly, when using "Two aspects per head" mode with the SE8C configured with a Board ID in the range 18 thru 36, the <p>SE8c will (by default) control the signal heads using Switch addresses which cannot be actuated by the typical LocoNet <p>throttle. <p>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 <p>ranges listed above. <p>This implied switch address configuration may be overriden by setting OpSw17 to "Closed" and then issuing a turnout <p>control message on LocoNet. <p>See Digitrax SE8C documentation for details.</li> <li>By default, the SE8C requires that its switch control messages arrive on the LocoNet cable's low-voltage <p>equivalent of the DCC track signals. This means that the SE8C will only react to switch control messages <p>on the DCC track signal, by default, so the command station track power must be on. If using the SE8C <p>on a "Standalone" LocoNet, it will be necessary to configure the SE8C to take its switch control messages <p>from "LocoNet messages", instead of from the "DCC track signal".</li> <li>JMRI's "SE8C Signal Head" assumes that the SE8C is configured in "Four aspects per head" mode.</li> <li>JMRI's support for flashing aspects on SE8C signal heads assumes that the SE8C is configured for "Fourth aspect is <p>Dark". <p>Note that when JMRI is flashing a signal head, there will be two LocoNet messages for each flash of the lamp. This can be <p>a significant amount of LocoNet traffic if many signal heads are flashing. <p>Additionally, the LocoNet switch commands are passed to the DCC track signal by the command station. The command <p>station can only process a limited number of LocoNet switch control messages. When LocoNet traffic exceeds that <p>capacity, the command station will reject the switch control message. This can manifest as "missed" flashes, "stuck lit" <p>and "stuck off" signal heads, as well as excessive LocoNet traffic. This problem may be mitigated by using the <p>SE8C on a "Standalone LocoNet" and configuring the SE8C to take switch control messages from "LocoNet messages".</li> <li>For the purposes of this Roster entry, SE8C OpSws are listed as "CV"s. </ul></html> CVs CV CV-Tabelle Taula-CV Tabulka CV CV-tabel Short Address eq 0 This sheet intentionally un-populated.
