connected to device
-terminal strips that appear outside slave box represent terminal strips not connected to device
When master is first physical device on network, as shown above, connect terminal strip to master and last
slave (slave 4) to begin network testing. Terminal strips for slaves located between the master and the last
slave are then connected, one, by one beginning with slave device furthest from master and continuing to
slave devices closest to master. Testing in the above graphic would occur first with slave 4, then slave 3,
then slave 2, ending with slave 1.

When master is not the first physical device on network, as shown above, connect terminal strip to master
and outer most slaves (slaves 1 and 4) to begin network testing. Testing in above graphic would occur first
with slaves 1 and 4, and then continuing by testing slave device 2, or slave device 3 until all network
wiring is tested.
Use below network wiring testing method when master is not first physical device on network.
Use below network wiring testing method when master is first physical device on network.
Follow wiring instructions below to avoid testing network wiring with stubs.

5200A networks must be configured point-to-point (instrument-to-instrument).
Network wiring cannot contain loops, stars, or stubs - figure 3.28.

Test Network Wiring and Configuration
Apply power to only the master and last slave device on the network. If the master
is not the first physical device on the network, apply power to the master and the
first and last physical slave devices on the network. See Network beginning on
page 93.
Step 8 Wire Communication Equipment
Communication equipment must be installed in order to communicate, either locally
or remotely, with the 5200A. The communication connection can be made locally
(RS232) or remotely with a serial to ethernet device. Only one connection method
can be used at a time. AquaManager supports both connection methods.
