Append Prefix “AP”
Up to 6 ASCII Characters can be prepended to the UBS-200L output data stream. Issuing “AP” followed
by the hexadecimal values of the 6 ASCII characters causes the characters to be pre-pended to the data
stream. There is no delimiter between the prefix and the remaining data stream. If a delimiter is
required, it must be specified as one of the 6 ASCII characters. All 6 characters must be specified. Use
“00” <NULL> characters if a prefix of fewer than 6 characters is required. See examples in Figure 12.
For reference, an ASCII table is included in Appendix 5 – ASCII Table.
Issuing “AP” with no parameter turns the feature off.
