LED Locations

ProtoCessor Module LEDs

PWR LED

When the PT-Link II is ﬁ rst powered up, the “PWR” LED should light

up and stay on continuously. See Figure 21. If the LED doesn’t light up,

check that the ProtoCessor is installed correctly and ﬁ rmly connected

to the Base Board.

GPI05 LED

The “GPI05” LED will light up when the Base Board and the ProtoCes-

sor Module have established communications. See Figure 21. This can

take up to 3 minutes depending on the number of units connected to

the PT-Link II . If it fails to light up after 3 minutes, check that the

ProtoCessor is installed correctly and ﬁ rmly to the Base Board.

LON LED

Once the unit is powered up, the “LON” LED will blink continuously

until the PT-Link II has been commissioned. Once commissioned, the

“LON” LED will remain off.

LA LED

Once the unit is powered up, the “LA” LED must be blinking constantly.

See Figure 21. If this LED is constantly on or off, the Module is not

working properly and needs to be replaced.

TX & RX LEDs

The “TX” and “RX” LEDs work together to indicate that communication

is being established with the desired protocol network. If both LEDs

are blinking, then communication is working properly. See Figure

21. If not, check the protocol network wiring and the baud rate in the

conﬁ guration ﬁ le.

D14 & D15 LEDs

The “D14” and “D15” LEDs work together to indicate that commu-

nication is being transmitted and received from the USB Port when

performing an update to the PT-Link II software.

If all of these tests are made and the controller still doesn’t operate,

please contact WattMaster Controls Technical Support at our Toll Free

number—866-918-1100—for assistance.
