6.3 PC Networking Applications
Every remote-PC must have a unique address. This unique address
is similar to the module address of the 7000 series. We call it a “slave-PC
address”. The module address of the 7000 series is limited to 256, but the
slave-PC address is unlimited. The user can connect thousands of PCs in
one RS-485 network by using a repeater, the 7510.

Refer to “NAP7000S User Manual” for software details. Using this
software, the host-PC can send out commands to remote-PCs, just like
sending commands to the 7000 series modules. The remote-PC will
receive these commands and execute the command if the destination
addresses matches it’s local address.

These remote-PC and 7000 series modules can use the same RS-
485 network. The host-PC can send out the 7000 series commands and
send out PC-networking commands at different times. The modules and
remote-PCs will receive their command respectively. This makes the
network very low cost, with high flexibility and reliability. This unique
feature is not found elsewhere in the world.
