T : HOST ACKNOWLEDGES UNIT RESPONSE
3
If the HFV generator receives an ACK (15h) from the host computer, it returns to the
normal waiting state. If the HFV generator receives a NAK (06h) from the host
computer, the HFV generator retransmits the response packet. The HFV generator
continues to retransmit in response to NAK transmissions until the host computer
stops the cycle. If the HFV generator receives no response, it assumes an ACK and
returns to the waiting state.

AE BUS COMMUNICATIONS TRANSACTION EXAMPLE

Figure 4-11 is a simplified graphic showing the steps in an example communications
transaction between a host computer and an HFV generator.

The following sections describe the command status response (CSR) codes returned
by the HFV generator in response to a command as well as the AE Bus commands for
