Table 8.47 outlines the response message.
TCM: Differential Remote Station Status
$PASHS,NME,TCM,x,c,[f]
This command enables or disables the RTCM rover data message, where x is the
port, A or B, c is ON or OFF, and f is the optional message output rate ranging from
0.05 to 999 seconds depending on the measurement update rate option installed.
If the command is set without a period, the DG16 uses the period set by the

this message period has been set, the period resets to the PER setting.
