•
Odd parity
•
One start bit, eight data bits, one stop bit
•
Low-order bytes are transmitted before high-order bytes.
The host computer must finish one transaction with the HPG generator before
it initiates another one, either with the same unit or any other unit.
Note:
The HPG generator sends data through pin 2 (
TXD.D
). This pin must be
connected to the receive pin (
RXD.D
) on the host computer’s serial
connector. The receive pin is normally pin 2 for a standard, 9-pin serial
port and normally pin 3 for a standard, 25-pin serial port.
AE BUS PROTOCOL
The AE Bus protocol uses pure binary data (nothing is coded in ASCII) and is
designed to facilitate direct communications between a host computer and the
HPG generator.
The AE Bus message packet combines a set quantity of bits and bytes in such
a way that groups of information can be sent over communications lines at
one time. Five types of information (fields) make up communications message
packets (see
):
•
Header (address and the length of Data field)
•
Command Number (commands are listed in
•
Optional Length byte
•
Data
•
Checksum
