Quick Tips
CONNECTION
The best way to connect devices in a MODBUS RTU is a 'DAISY CHAIN' method.
MAXIMUM DISTANCE
You may encounter problems when powering gas sensors beyond 500 yards from one control
panel, in this instance, contact your supplier.
TERMINAL RESISTANCE
Signal communication issues may occur. To avoid this, terminating at each end of a chain may
help the quality of the data signal by turning on the 120ohm terminal resistor switches.
GROUNDING
If you are encountering noise or irregular or abnormal problems with a Modbus link, the problem is
likely related to grounding, incorrect shielding or wiring main power next to Modbus wiring.
CABLES TO USE
A shielded and twisted pair cable is used. The shielding can be of 2 types: braided [like a mesh of
thin conducting wires] or like a foil [consisting of a thin sheet of metal covering the twisted wires].
PROTECTION
High concentrations of alcohol found in many products may damage, deteriorate or affect the gas
sensing elements of Detectors – such as; wine; deodorants; stain removers; thinners etc.
IDENTIFICATION
Remember to individually ID each connected detector by configuring the ID switches on the circuit
board. Make a plan, map and/or note of the location of all connected detectors for tracing and
locality purposes.
