Sensoray 417 - Manual (Page 23)

Instruction Manual 22
50Hz Reject Mode
This command changes the digitizer’s integration period from 16.7ms to 20.0ms, enabling the
coprocessor to reject 50 Hertz differential line noise. This command should be used in systems tar-
geted for 50Hz power environments.
After a hard or soft reset, the digitizer defaults to 16.7ms in order to reject 60Hz line noise. After
invoking this command, the coprocessor can be restored to the 60Hz rejection mode only by a hard
or soft reset.
Note: all timing specifications assume the 417 board is operating in the 60Hz rejection mode.
COMMAND: (100)
RESPONSE: NONE
VB Code Example:
‘*****************************************************************
‘ This procedure switches the 417 to the 50Hz Reject Mode.
‘*****************************************************************
Sub Set50HzRejectMode(BasePort As Integer)
Call SendByte (BasePort, 100)
End Sub
