: ?t cr begin 13 emit .int 30 30ms key? until; Program to check the internal clock ticking
master-sync Set internal clock (and backup real-time clock) to the RTM time (reboot does the same thing)
2400 /sci2 Set baud rate of the GPS serial port to 2400 bps for accessing the RTM
rtm-open Enable access to the RTM module
+1ppm Change the frequency of the RTM (precision clock)
-1ppm Change the frequency of the RTM (precision clock)
cancel Restore the RTM module to normal state using the calculated trim value
: slower 2400 /sci2 rtm-open 0 do -1ppm 3 30ms loop rtm-close; Program to define "slower" and "faster" commands
: faster 2400 /sci2 rtm-open 0 do +1ppm 3 30ms loop rtm-close; Program to define "slower" and "faster" commands
n slower Change the RTM frequency by n ppm
n faster Change the RTM frequency by n ppm (maximum adjustment is ~30-40 ppm)
rtm-close Disable access to the RTM module
rtm-open 2400 /sci2 cancel rtm-close Program to restore the RTM to normal operation
4800 /sci2 Restore baud rate for GPS connection
rtm-trim ? Display a number for clock trim in the CMOS backup memory in the power distribution module
trim# dup -1 xor swap rtm-trim 2! rtm-trim backup! Program to set the trim# to CRM CMOS register
?lithium Report the state of both the battery comparator and the switch line
+rtm-battery Switch the backup on and reports the status (before and after)
reminder Set the clock into timer mode (sets a maximum off time of 10 min)
manual Start the system in timer mode
sleep Switch off the system using watch-dog reset
time wake-up Set start time in format: mm dd hh mm
.limits Display setting in the units shown in the status block
.mean Show mean voltage of power supply
.st Status reading from power distribution module
n power-down Switch off the channel
n power-up Switch on the channel—if not disabled
n enable Reenable switching on
n disable Switch off the channel and prevent further operation; monitoring is not affected
n remove Remove control and monitoring
n install Adds the channel for control and monitoring
vl vh ch set-limits Set limits of power control; vl = switch off voltage, vh = high limit, and ch = channel of PDM
o/p ? Check the semaphore status; this should show zero (i.e., no task currently outputting to the display/status)
0 0 o/p 2! Manually reset the semaphore when there is a problem to stop sending status messages
OBH available command set:
.d-day Show deploy date setting day month year
.soh Request ocean borehole seismometer health status
component unlock Unlock the component (component is of; e/w n/s z all)
