Alternatively, the PL-485-BT is equipped with an RJ45 jack that carries the same
RS485 A(+), B(-) and GND signals among the eight pins within the jack (see Figure 1
for pinout). This port is very practical since it can be used to quickly connect to
ProLon controllers that are equipped with a similar RJ45 jack using standard CAT5
cable (plug-and-play). This approach saves time since there is no need to cut and
strip wires.
NOTE: The RJ45 jack is NOT an ETHERNET port. The PL-485-BT does NOT SUPPORT
ETHERNET.
OPERATING TIPS & TROUBLESHOOTING
POWER & CHARGING
The PL-485-BT is equipped with a rechargeable Lithium-Ion battery. It charges via the USB port. It is also equipped
with an ON/OFF button. The switch must be in the ON position for the converter to operate as a communications
device (Bluetooth or USB). When the converter is not being used, switch to the OFF position to conserve battery
life. The converter’s battery can still be charged even when the switch is in the OFF position.
Upon Power-Up, the POWER LED will be ORANGE for a brief period of time (approx. 45 sec) while the battery level
is being calculated internally. After this period, the POWER LED will be:
•
Blinking RED when USB unplugged
•
Solid RED when USB plugged and charging
•
Solid GREEN when USB plugged and the battery has been fully charged
The current battery level can be displayed anytime in the ProLon Focus Application. The POWER LED remains OFF
when the switch is set to the OFF position.
Note: While a Bluetooth connection is open, USB to RS485 communication is disabled. (The converter battery will
still continue to be charged when USB is plugged even if Bluetooth is active).
ONCE FULLY CHARGED, THE BATTERY CAN LAST APPROXIMATELY 15 HOURS WHILE ACTIVELY
COMMUNICATING TO A PROLON SYSTEM, AND UP TO 22 HOURS WHEN IDLE (POWER SWITCH LEFT ON). IF
THE POWER SWITCH IS OFF, THE CONVERTER CAN LAST FOR SEVERAL WEEKS.
THE BATTERY TAKES APPROXIMATELY 2-3 HOURS TO COMPLETELY CHARGE UP AGAIN.
