Data Input Checking Method
By selecting [MENU] -> 9.SERVICE -> 6.MAINTENANCE -> 1.I/O MONITOR and
opening the "IEC-61162" tab on the I/O MONITOR window, IEC data inputted
between TB6-#3 (GNSS RD-A) and #4 (GNSS RD-B) can be monitored.
Monitoring is independent of the following settings:
• [MENU] -> 5.SYSTEM -> 4.POSITION -> POSITION setting
• [MENU] -> 9.SERVICE -> 3.RT SETUP -> 1.SETUP -> FORMAT setting

4.3.5 [5. DATE/TIME]

Date/Time data are used to timestamp on printouts of DSC communication LOG and
TEST results. When Date/Time data ZDA or RMC is inputted (in order of priority
presented), "EPFS" will be displayed in the [SOURCE] column.
If no data is inputted, "INTERNAL" will be displayed in the [SOURCE] column, and
data with date and time set manually will be set to RTC mounted on the T-CPU board.
If RTC time deviates from ZDA or RMC time (in order of priority presented) by 10 or
more minutes, adjust the RTC time to ZDA or RMC time (in order of priority
presented).
GGA and others are not used to update RTC due to a lack of date data.
Reference)
"TIME" included in DISTRESS MESSAGE and "UTC" displayed on the RT
window and the SCAN window is positioning time included in positional data in use.
ZDA or RMC sentence is used (in order of priority presented) for time data for
timestamp data.
However, the handling of RMC data varies with the setting of Submenu-2
"FORMAT" in [MENU] -> 9.SERVICE -> 3.RT SETUP -> 1.SETUP ->
"FORMAT."
