Development Serial Communication Commands

A-4 | Dycor CG1000-RTP Oxygen Analyzer
These commands are used during initial serial communication design.
Echo (A)
Test the serial protocol and line integrity.
Any text sent to the CG1000-RTP is echoed back to the host.
Bad Command (B)
Just returns a bad command (error code 01) reply.
Acknowledge (C)
Returns a simple acknowledge.
This command can also be used later to check that the controller is on-line
and ready to communicate.
Data Format (J)
Check how data is output through the serial link.
For each variable that is accessible through the Read Number and Write
Number commands, a string is returned that describes the format of the
number. This response data consists of three characters:
Format
F Float
H Hexadecimal
u unsigned decimal
Due to the nature of EEPROM memory, each location in the memory has
a limited number of writes allowed (approximately 10,000). The location
character can be used to determine where the data is stored internally to
the CG1000-RTP and act accordingly.

r read only
