okay, first i want to show what i was going off of and what i was trying to check. to quote kruetz:
"First tests after successful assembly
Check all the connections, measure resistance across 15V terminals, Motor power supply terminals and motor terminals, no short circuit should be present.
Connect the encoder cable (with the pins 8 and 2 jumpered on the encoder side), RS232 cable to PC, USB cable to PC, and 15 Volt power supply. Connect the motor terminals to the right connector, but don't power on the motor power supply for this test. Do not insert the UHU chip on its socket yet.
Turn on the 15 V power supply and check the 5 volts between the 15V power supply GND terminal and pin 10 of the UHU chip socket. If OK, turn off the 15 V power supply and wait about 10 seconds for the voltage to drop to zero, then insert the UHu chip on the socket"
now if i understand correctly, i should be checking for 5vdc on pin 20? which is directly accross from pin 10? and this is all on the socket for the microcontroller?
sorry, just want to avoid any confusion!  |
