the bit pattern (the least significant bit is on the right). The bit
pattern read from the port will be displayed until you press another

• Remote Interface Operation: From the remote interface, you can read
an 8-bit byte from one port or a 16-bit word from both ports using the
following commands. If you are going to read both ports simultaneously,
you must send the command to port 01 and neither port can be
included in the scan list.
SENS:DIG:DATA:BYTE? (
@302) Read port 02
SENS:DIG:DATA:WORD? (
@301) Read both ports together
To redefine the scan list to include a digital read (8-bit read only),
send the following command.
