4.When applying GPS instruction, COM1 has to be applied in Master mode, i.e. M1312 has to be enabled to sending request. In addition, M1314 = ON indicates receiving completed. M1315 = ON indicates receiving error. (D1250 = K1, receiving time-out; D1250 = K2, checksum error)

5.Associated M flags and special D registers:

No.	Function
M1312	COM1 (RS-232) sending request
M1313	COM1 (RS-232) ready for data receiving
M1314	COM1 (RS-232) data receiving completed
M1315	COM1 (RS-232) data receiving error
M1138	Retaining communication setting of COM1
D1036	COM1 (RS-232) Communication protocol
D1249	COM1 (RS-232) data receiving time-out setting. (Suggested value: >1s)
D1250	COM1 (RS-232) communication error code

6.Before applying the received GPS data, please check the value in D+9. If D+9 = 0, the GPS data is invalid.

7.If data receiving error occurs, the previous data in D registers will not be cleared, i.e. the previous received data remains intact.
