Why is the voltage out of range on the Johnson Controls Gateway BAS Bus Terminal Block?
If the voltage is significantly outside the specified range when measuring the BAS Bus Terminal Block, it is possible that the transceiver or associated circuitry is damaged. Double-check that switch S2 (BAS EOL) is in the 'ON' position during measurement; otherwise, the voltage readings will be inaccurate.
What to do if the firmware update does not start automatically on Johnson Controls Gateway after inserting the USB?
If the firmware update on your Johnson Controls Gateway does not start automatically after inserting the USB, try cycling power to the SC-EQ board. You can do this by removing and reconnecting the power plug on the SC-EQ board.
What to do if Johnson Controls Gateway SC-EQ fails to validate the firmware?
If the Johnson Controls Gateway SC-EQ fails to validate the firmware at initial power up or after a firmware upgrade, try cycling the power to the SC-EQ and updating the firmware again.
What to do if Johnson Controls York Smart Equipment SC-EQUIP Gateway SC-EQ could not load a firmware update?
If the Johnson Controls Gateway SC-EQ could not load a firmware update, attempt to load the firmware update onto another USB thumb drive and perform the update again.
What to do if BS BUS LED is off and SC-EQ board isn't communicating on Johnson Controls York Smart Equipment SC-EQUIP?
If the BS BUS LED is off steady and the SC-EQ board isn't likely seeing valid communications, use a DC voltmeter to perform simple voltage measurements on the SC-EQ board and BAS communication bus.
How to fix 'no firmware present' error on Johnson Controls York Smart Equipment SC-EQUIP Gateway?
If there is no firmware present on the Johnson Controls Gateway, perform a firmware update to resolve this issue.
Why are voltage readings fluctuating during communication on Johnson Controls York Smart Equipment SC-EQUIP BAS Bus?
If you observe fluctuating voltage readings during communication on the BAS Bus, ensure the bus is properly terminated. The voltage readings may vary somewhat depending on bus loading and the type of voltmeter used.
What to do if Johnson Controls Gateway SC-EQ is not responding?
If the Johnson Controls Gateway SC-EQ is not responding when polled by the BAS system, the MAC address should be checked to see if it is set to the desired address.
Why is the power LED not illuminated on my Johnson Controls Gateway?
If the power source is present at the SC-EQ power terminals, then the Johnson Controls Gateway SC-EQ is faulty.
