The master verifies the fact that unit 6 is a Model ___D. Refer to
Table 3-2 "D Series Controller to SyriXus Series Pump" for the
model name returned for each of the SyriXus series pump
models.
In this example, the master and the network controller are a
single unit. If they were separate units, the master would send
the inquiry to the network controller; then the network
controller would send the message to the slave unit the next
time it is polled. The slave would respond with the message to
the network controller. The next time the master is polled, the
message would be relayed.
