Each string value will be referred to as S1, S2, etc. within the remainder of the Script Record. .
With respect to the Sensor Record that refers to this Script Record, these values can be inputs to
Data Output Records as specified in Section 10.4.4.
SET_CHECKSUM type, modulus [, offset]
Defines how checksums will be calculated within the Script Record. The permitted checksum
types are listed below.
273
The checksum type can be entered in either uppercase or lowercase.
CRC_16 (standard CRC-16).
CRC_CCITT (standard CRC-CCIT)
XOR (Logical XOR between all characters within the delimiters is used in NMEA messages).
SIMPLE (ASCII sum of all characters within the delimiters).
The modulus
274
defines which portion of the calculated checksum will be used. for example, a
modulus of 100 means that only the portion of the calculated checksum that is below 100 will be
used. As another example, a modulus of 256 means that only the portion of the calculated
checksum that is below 256 will be used.
The SIMPLE checksum type requires both the modulus and the offset applied to the ASCII sum
before the modulus is taken.
Action Commands
NO_COMMAND
No action is taken.
TURN state channel
Turn the specified channel to the state that is ON or OFF. state is either ON or OFF. channel is
a value between 1 and 5 or 18 and 23. The channels are as follows:
Channel Meaning
1 5 V Switched Voltage A
2 5 V Switched Voltage B
3 12 V Switched Voltage A
4 12 V Switched Voltage B
5 12 V Switched Voltage C
18 - 23 Digital Output
WAIT time
Wait for the specified length of time in milliseconds, and then flush the buffer. Wait times from 1
millisecond to 5 minutes (300,000 milliseconds) are permitted.
273
Contact Coastal Environmental Systems for other checksum types if none of these meet your requirements.
274
A modulus is used to calculate the remainder generated when dividing two numbers.
