Command: SPx [Parity Command]
Applicable Options: SP0 / SP1 / SP2 (Please refer ‘H’ Command menu for applicable meanings of
mentioned options)
The change of parity configuration can be done using this command. Different options for the parity
settings are as below:
NOTE: It is necessary to change the value of data bits in hyperterminal settings along with the Parity, if
user changes the parity of GPS Master Clock Model MC-1-M COM2 terminal as per applicable value
mentioned below:
SP0: No Parity
8 data bits
SP1: Odd Parity
7 data bits
SP2: Even Parity
7 data bits
Same as SBxx command, the communication stops as soon as you finish the command and press ‘Enter’
once. This is because the protocol settings at GPS Master Clock Model MC-1-M and HyperTerminal do
not match. To correct this, follow the steps 2 and 3 of SBxx command. Now correct the parameter to
match with desired/set ones. In this case, take care of changing the databits to 7, when the parity is either
even or odd.
After setting the parity in this setting window, follow the steps 5 and 6 of the SBxx command. The time
data will again re-appear. You can check present settings using ‘L’ command.
NOTE: The parity settings will not be effective in NMEA output on terminal COM1.

Command: SSx [Stop Bit Command]
Applicable Options: SS1 / SS2 (Please refer ‘H’ Command menu for applicable meanings of
mentioned options)
The number of stop bits in the serial communication can be set as 1 or 2 using this command. The
options are simply two:
SS1:
One stop bit
SS2:
Two stop bits
The steps to follow are same as SBxx and STx command.

Command: Z
This command is to enter the time offset of any particular region/country with reference to the UTC. Every
country local time works at some time offset with respect to UTC. Time offset can be positive or negative
