16 Remote Automated Control Requirements
16.1.1
The S2000 system is designed to provide remote automated control of the UV
spot curing system from a PC.
16.1.2
The S2000 PC software requirement specification below is used to describe
the communication protocol between the S2000 unit and a PC.
WARNING:
If the user does not observe and adhere to the protocol and
command timing specifications, abnormal unit operation will result!
16.2 Com Port Configuration:
Baud rate:
19200
Data bits:
8
Parity:
None
Stop bits:
1
Flow Control:
None
16.3 Message Format and Protocol:
16.3.1
All commands sent to the S2000 and responses from the S2000 include 3
pieces of data: the command section, a CRC
8, and a carriage return (“\r” in C
code or chr$(13) in basic code). The CRC8 (one byte value) is entered as a
hex string. Please refer to CRC8 routine for details in section 16.7
16.3.2
When the carriage return character (CR) is received, the S2000 will respond
with an error message if there is a problem.
For example:
Error Message Response:
“Err67\r”
16.3.3
If there are no errors, the S2000 will respond as indicated below. In the
example, the XX presents one byte CRC8 value.
Note:
The command “CONN18\r” must be sent out first to establish
communication with the connected PC. If a “READY0A\r” is received from
the S2000, communications can commence with the unit, otherwise, the
command “CONN18\r” should be resent until the response “READYOA\r” is
received.
