Figure 12. Using the termination plugs supplied with the ES4000A for mixed
wet- and dry-line operation. In this example, channels 5 and 6 are powered from
a PS2000L Power Supply (wet lines), while channels 3 and 4 are operated without
power (dry lines). Any remote station connected to channel 3 or 4 must supply its
own power.For example, a US2000A that is powered by a PS-L Power Supply
could be connected to channels 3 and 4. The advantage of dry-line operation is
that intercom stations may be operated over a much greater distance.

tion about the cable num-
bers, see page22.
