Parity Selection (RS-232)
You can select the parity for RS-232 operation. The meter is configured for even
parity with 7 data bits when shipped from the factory.
– Select one of the following: None (8 data bits), Even (7 data bits), or Odd (7
data bits). When you set the parity, you are indirectly setting the number of
data bits.
– The parity selection is stored in non-volatile memory, and does not change
when power has been off or after a remote interface reset.
– Front Panel operation: set the parity under the 4: PARITY command in the I/O
menu.
See also “To Set the Parity” on page 211.
– Remote operation: use the following commands to set the parity:
SYStem:COMMunicate:SERial:PARity {EVEN|ODD|NONE}
If you change the parity over the remote interface, you may lose control of the
meter.
