Note:
The slave address appears as the slave subnode at node properties.
Disable the Termination Relay on all devices except for the first and last 6.
device on the network. Menus → System → Communications → Network
→ Termination Relay.
Verify that the Termination Relay is enabled on the first and last device 7.
on the network.
For master node:
8. Press

at master submenu. At assign slaves menu,
select the slave address configured in step 5 above. Press enter. Enable
one slave at a time using
softkeys . See Testing Network
- page 57 for the required testing network wiring.
Press 9. to save configuration and return to Run Screen.
Each slave must be tested one by one. Insert network termination strip 10.
and apply power to the master and the last physical device on the network.
If the master is not the first or last physical device on the network, apply
power and insert network terminal strip on the master and on the first and
last physical devices on the network. Refer to the network wiring instruc-
tions for detailed testing information beginning on page 52. Testing for
proper wiring and configuration can be done one of two ways:
A. After performing step 9, wait at least 30 seconds and then reenter the Com-
munication Master submenu. If the serial number of the slave is displayed
next to the slave address number, the communication network is wired and
configured correctly.

OR
B. After performing step 9, wait at least 30 seconds and then poll the slave
node using AquaManager. If the serial number of the slave is displayed next
to slave address number, the network is wired and configured correctly.
Apply power. Insert network termination strip to 5200A/5400 units as 11.
described in the network wiring instructions beginning on page 52. Repeat
network configuration directions starting at step 8 until network wiring
for master and all slaves has been tested.
Notes:
An Event and General alarm (if enabled) will occur if, after ten queries, -
an enabled slave does not respond to the Master.
Configuring a 5200A as a Master overrides any slave configuration that -
had been previously saved.
Slave alarms (slave alarm at master and 5200A alarm emails) will not oc- -
cur if slave node serial number is not recognized at master node at steps
10. A or 10. B above.
Termination Relay
Menus → System → Communications → Network →Termination Relay
The termination relay must be enabled on the first and last 5200A on a network. All
other devices should have the termination relay disabled.
