Communication Protocols

Three communication protocols are available:
OEM communications protocol
Data Terminal (DT) protocol
CAN protocol
The XLP 6000 firmware automatically detects the communication protocol.
The DT protocol can be run via an ASCII data terminal because no sequence
numbers or checksums are used. For instructions on using a Microsoft Windows
Terminal Emulator, see "Using DT Protocol with Microsoft Windows" in this
chapter.
Note: Tecan Systems recommends using the OEM protocol for RS-232 and
RS-485 interfaces. It provides increased error checking through the use of
checksums and sequence numbers.
Once the XLP 6000 detects either the OEM or DT protocol, it will ignore the other
protocol until the next power cycle.
OEM Communication Protocol
OEM communication is a robust protocol that includes automatic recovery from
transmission errors. Table 3-3, OEM Protocol describes each setting within the
OEM communication protocol.
