7. Log to USB Drive. This check box field is used to indicate to the RMU5 that it should use the internal optional
USB drive card for storage of log files and data log files. If the internal optional flash drive is not installed, this
check box should be un-checked.
8. No Debug Events. The RMU5 system log can output very detailed logging messages to aid in diagnosing potential
problems. This verbose logging can create large files quite quickly. To reduce the amount of information that is
logged, so that only critical events and information events are shown, uncheck this box.
9. Log File Path. This field is used to select the destination directory for the log files. With the internal optional USB
drive card installed, this field should be set to "Hard Disk\".
10. AC Fail Flag Register. When the RMU5 is used in MODBUS slave mode, failure of AC input power may be polled
by requesting the data from the holding register indicated by this field. The AC failure indicated in the MODBUS
register is latching and requires the host to reset the flag. This field sets the start of the MODBUS register block
used for accessing this function.
11. Realtime Clock Registers. When the RMU5 is used in MODBUS slave mode, the internal real time clock may be
queried or set by a remote master. This field sets the start of the MODBUS register block used for accessing this
function.
12. GPS Status Registers. When the RMU5 is used in MODBUS slave mode, the optional GPS timing control module
may be queried by a remote master. This field sets the start of the MODBUS register block used for accessing this
function.
13. Fixed Point Readings. When the RMU5 is used in MODBUS slave mode, it is possible to switch the readings
representation format from IEEE 754 floating point to 16-bit fixed point. In 16-bit fixed point mode, the range of
readings values is from -327.67 to 327.67. This option would be set if the RMU5 is used with a MODBUS master
that is incapable of utilizing floating point representations for data.
14. Alarm Reporting Window Starting/Ending Hour. In communications modes other than MODBUS, the RMU5 will
autonomously report alarms to the host. These two fields determine at which times the RMU5 can report alarms to
the host. The alarm allowable times are inclusive of the limits values entered. Note that all times on the RMU5 are
UTC times—local time zone is not taken into account. Note that this setting is not applicable to Skywave IsatM2M
and MODBUS communications modes.
15. Periodic Reports. In communications modes other than MODBUS, the RMU5 can be programmed to periodically
send data reports to the host. The fields in the group allow the hour and minute time of day of the reports to be
selected. The number of days between reports can also be selected. To enable this feature, check the "Periodic
Enable" check box. . Note that this setting is not applicable to Skywave IsatM2M and MODBUS communications
modes.
16. Allow Reports On. In communications modes other than MODBUS, the RMU5 can be programmed to periodically
send data reports and alarm reports to the host. The check boxes in this group can be used to limit the days of the
week when reports will be sent. . Note that this setting is not applicable to Skywave IsatM2M and MODBUS
communications modes.
