1.5v is not a valid TTL logic low (0) or a TTL high (1). Set to active high and it should measure ~5v. Then see if you can jog the motor in + and - directions. You should be able to jog it both directions in the MDI panel also. If that works, change the keyboard arrow key definitions to get that working correctly as well.
