                Board ID may be between 1 and 24 if using "Four Aspects per head" mode

                <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.

            </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.
