channel over the normal white/blue wire pair and another RS-485 channel over the

yellow/violet wire pair. An additional Click! 304 is needed to convert the data sent over

the yellow/violet wire pair back to RS-232 before connecting to surge protection.

If you elect to use an alternate cable for power, you may also want to select an alternate

cable for RS-485 communications. Some options include the Belden 3105A (Paired –

There are many reliable options available for wired power and communications

connections (see Table 10).
