Appendix A
Determining Number of RS-485 Ports Needed
A-2
Turn off, tag and lockout the breaker that supplies power to the IQ Control
Box.
1. Go to each IQ Control Box and determine/record its mode/role setting (DIP SW 1 – See “Setup Switch
Chart” on page
15.) or refer to site documentation to identify IQ Control Boxes that are set to standalone and/
or manifolded mode and their assigned STP/tank.
2. If in Standalone mode, up to four independent IQ Control Boxes may be daisy chained to a single RS-485
port.
3. If in one of the manifolded modes, IQ Control Boxes must only be connected to IQ Control Boxes on the same
manifold (one RS-485 port per manifold).
4. Manifolded and direct mode IQ Control Boxes may be combined on the same TLS-450PLUS and may share a
single RS-485 Comm Module as long as they are connected to different RS-485 ports.
5. After determining the number of RS-485 ports needed for the site, it is recommended to install the site RS-
485 cables.
