1.0 Connection guide
The SMIC cable is designed to communicate as a one to one device. Networking is not supported with
standard SMIC cables. If networking is needed for more than one Operator Interface, consult factory for special
cable requirements.
1.1 Installation Guidelines
Environmental Considerations
The SMIC cables are designed for use in a clean environment. It is designed to operate from 32 to 113 °F (0 to
45 °C) temperatures, as found in most industrial environments. It is not be suitable for use in applications where
it is exposed to the elements.
The SMIC cables are not NEMA rated. This means that gases, dusts and fluids have the potential to affect
operation and or corrode the components.
Do not operate the unit in areas subject to explosion hazards due to flammable gases, vapors or dusts.
Electrical Environment
The circuitry is designed to resist the effects of electrical noise. This does not guarantee noise immunity in
severe cases. Be sure to use proper wire routing and grounding to insure proper operation.
Note:
The SMIC cables with signal conversion electronics should only be extended at the PLC end of the cable.
Caution
Restrict cable length to less than 500’ (150m) for RS485/422 devices and 50’ (15m) for RS232
devices to avoid communications problems. Communications problems cause the display to show
“PLC no response...” until communications can be established.
Shielded cable must be used for long lengths or cables run in an electrically noisy environment.
Do not run cables next to AC power lines or near sources of electrical noise.
Be sure that the cable ends have been inserted all of the way into mating connectors and are secure
Mechanical Environment
Avoid installing cables in environments where severe mechanical vibration or shocks are present.
