Note:
It is essential that wires be terminated cleanly. Nicks (stray wires, not -
cleanly terminated) can result in unreliable network communication.
CAUTION : Run high and low voltage wires/cables through separate bulk-
head and conduit.

Terminate wires as described using category 5 cable: (color scheme may 5.
be different than described below.)

Pair #2 wires: solid orange and white with orange stripe -
1 wire green -
Secure unused wires to avoid potential for shorting -

Figure 3.26 is a wiring diagram for the most common 5200A network configura-
tion where a master 5200A is the first physical device in the network. Additional
network diagrams are provided after step 8.
Figure 3.26
Wire all network terminal strips prior to network testing, but only con- 6.
nect a network terminal strip to the first and last devices on the network
(*see note below). Configure network menu and follow testing procedure
as described - see page 93. Slave devices are tested one by one as they are
added to the network. Network testing cannot be done if stubs exist (**
see note below).
Notes:
*If the master is not the first physical device on the network, place network -
terminal strip on the master and on the first and last physical devices on
the network. (In this case two slaves will need to be tested at the same
time.) - figure 3.27.
**A stub is created when the last wired network terminal strip is not con- -
nected to a network slave - figure 3.24.
