The alternative is to use a cable as shown below. You will need to use a power supply to supply

power for the PAC serial ports when using this type of cable, as the handshaking lines are not able

to supply power to the PAC. The loop back connections on the PAC end don't actually do anything

as these same connections are made internally and so these can be left off.

1.3.3.8 How much logic ?

Problem

How much logic is possible in the PAC ?

Solution

Unfortunately, there is no simple answer to this question. The PAC is intended for small amounts

of logic. To implement large amounts of logic, use a Colour C-Touch, HomeGate, Schedule Plus

or multiple PAC units.

There are several things that can be done, which are discussed in detail in the How Much Logic Is

Possible topic of the logic help file.
