AE BUS (HOST) COMMUNICATIONS

The following sections describe the AE Bus (Host) port communications.

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
Pinnacle.
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 Figure 4-
16):
• Header (address and the length of Data field)
• Command Number (the commands are listed in Table 4-18 on page 4-63)
• Optional Length byte
• Data
• Checksum
