Wiring Connections
The Stride MQTT Gateway comes with a female 5-pin
plug-in connector for its power and RS-485 connection.
The gateway can be powered from the same 12 to
24 VDC source that is used to power your other
devices. Recommended DC power supplies are
AutomationDirect.com part number PSL-12-010 or
PSL-24-010.
The device uses a 2-wire RS-485 interface. It has an
internal terminating resistor, so this device must be at
the end of the communications daisy-chain.
Avoid routing signal cables near power cables (motors,
induction ovens, inverters, etc.), and use shielded cable
to connect signals. We recommend AutomationDirect
Part #L19954-1 or equivalent data cable to connect
RS-485 serial devices.
