LED BOX 1 For ECAL: led@130.199.60.245

LED BOX 2 For HCAL: led@130.199.60.250

purpose: set active LED row and column bits and set Bias Voltage from single command line. Note lowercase “L” option to run as listening socket.

ð  Login as: led@LEDECAL:~/documents

ð  Run =>  ./led_sok3  (with the following command line options)

options:  

Required: -l# -> set local or socket mode 0= socket mode, 1= local mode (run from within SSH session command line)

-w# -> 0= read back only, 1= write new values
-r# -> set active row bits (0 - 31)

-c# -> set active column bits (0 - 1023)

-v# -> set DC Bias Level in unit Volts (0 or in a range from 10.## - 30.00)

NOTE: v bias is stored in DAC EEPROM, but before taking LED run, it is advised to check v bias with: ./led_sok -l1 -w0  

Write Example: Set all LEDs in all rows and column active and set bias voltage to 22.00V
