MX51x LAN Crossover (Null) Cable Diagram

The interface between the two (or more) units takes place over a high speed (100 Mbps)

data link. The master unit must be connected to the smart GPS antenna unit (MX421,

MX521A, MX525A, or MX575A). The master unit receives the position data then transfer

it to the slave unit(s) at a one second rate (the same as the position calculation). Due to

the high speed data link, there is virtually no visible position delay between the two (or

more) units.

When two (or more) units are first configured as master and slave(s), the master listens

for a configuration polling message from the slave(s). Once the master recognizes

the slave’s polling message, the Common Data Base (see Table below) is downloaded

from the master to the slave(s). This function also takes place each time the units are

powered up.
