Power Up Sequence
After powering up the PLR, the HB LED indicator should toggle at a rate of 10 times per
second and the four status LEDs should remain blank.
Bootstrap Messages
If the PLR is in bootstrap mode, the HB LED indicator will toggle at a rate of 10 times per
second. If the PLR is in production mode, it will toggle at a rate of one time per second.
Refer to Figure 31 for the codes that are shown on the status LEDs during the bootstrap
mode. If an error occurs, the ERR LED lights up along with the error code on the other
three status LEDs.
ERR 0 1 Code 2
bdb - waiting to receive valid bootload frame type
bnb - bootload file is not for this device (wrong node address, file type, etc.)
bFb - error condition (usually a checksum error), PLR will retry up to 16
times before stopping
b-b - FPGA unable to configure

Production Mode
If there are no errors or status messages to report, the status LEDs remain blank during
production mode. Refer to Figure 32 for messages that may be shown while the PLR is
operating in production mode. If an error occurs, the ERR LED will light up along with the
error code on the other three status LEDs.
