I/O CONFIGURE
This field allows you to select the data format for the User Data field.
• ASCII selects ASCII character entry.
• Hex selects hexadecimal character entry. This choice is available for sending
messages that require non-English language character sets.
When the User Data field is selected, the front-panel knob is used to enter
characters.
HP-IB Example
"CDMA:SMS:MDM 'Hex'"
sets the User Data field data format to hexadecimal.
Operating Considerations
If you select Hex the Test Set expects an even number of hex characters to be
entered in the User Data field. Each pair of hex characters represents a byte of
data. If an odd number of hex characters is entered in the User Data field , the least
significant four bits of the last byte will consist of zeroes.
