Installation and Wiring
Step 7 Wire Network
Multiple 5200A, 5400 and 5500D-1, 5500D-2, 5500D-4 instruments can be net-
worked using the RS485 network ports. A node network consists of one master and
up to 31 slaves. On a network, the master is the point of access for the AquaManager
PC soware program. In addition, the master sends all serial to ethernet device
emails. Communication hardware (RS232 or serial to ethernet device) is installed
on the master instrument (node) only.
RS485 network wiring can span distances up to 4000 feet (1220m). This maximum
distance (4000 ft) is for the total network distance, not the distance between net-
worked units (*see Notes below). RS485 ports are optically isolated for safety, to re-
duce noise, and to help eliminate ground loops. No further isolation is required.
Network trac refers to the constant communication between the master and all
the slaves on the network. For example, slave node 3 is congured to generate an
alarm if the temperature drops below 70°F. e master node is congured to send
alarm emails via TCP/IP using the serial to ethernet device. e master node sends
an email alarm when slave node 3 reports a temperature value below 70° F (after
alarm hold off time) to the master.
AquaManager is a valuable tool for monitoring and controlling node networks.
Notes:
- *Use an RS485 Line Extender/Booster for distances over 4000’ (1220m).
Communication failures may occur without it. Mount the booster in an
area where it is protected from moisture.
- Multiple networks connected to a PC via RS232 require separate PC COM
ports for simultaneous AquaManager mapping and autopolling.
- Legacy 5200s can not be on the same network as 5200As, 5400s or 5500D-
1, 5500D-2 and/or 5500D-4 instruments. However, Legacy 5200s can
communicate with AquaManager and Legacy 5200 data will be stored in
the same database as 5200A, 5400, 5500D-1, 5500D-2 and 5500D-4 data.
- Network trac speed operates at ~ 230 KB and is not user selectable.
- Remove network terminal strip from any networked slave that is not
powered. Network rewiring is required if a stub (*see next note) is cre-
ated when a slave is taken o the network. See valid network congura-
tion - gure 3.28
Note:
- *A stub is created when the last wired network terminal strip is not con-
nected to a network slave - gure 3.24.
