What if I need to cover more than 700 feet (213 meters)?
You can cover much greater distances by using Series 90-30 communications option modules. For
example, Genius Bus Controller Modules (GBC) can communicate at distances up to 7,500 feet
(2,286 meters) over a shielded twisted-pair cable, as shown in Example 1 below. Or, serial
communications with Communications Coprocessor Modules (CMM) using the RS-485 standard
can cover up to 4,000 feet (1,219 meters), as shown in Example 2 below. And virtually unlimited
communication distances can be attained with modems and telephone lines or radio transmitters.
Also, there are numerous networking options available such as Ethernet or WorldFIP.
