5-3.5.4 Innotech Repeater Modules
The Innotech Repeater modules IR11 and IR12 (Figure 5-12) can be used with both the Genesis II
Direct Digital Controller and MPCII Mid Points Controller. The repeater’s function is to rebuild each
data byte before retransmitting it.
When a repeater is added to a network it eectively creates two separate networks.
This means users must apply all the rules to each side of the repeater as if they were actually two
completely separate networks. All primary network rules apply without variation. All repeaters do
have So Earth features. They do not negate the need for a hard earth on either side of the repeater
network sections. It is not recommended to earth both ports (1 & 2) right at the repeater as this
would defeat some of the advantages of the port isolation. Port 2 (remote port) should always be
earthed on the remote side.
