Reading from/Writing to ID Tags
• Read ID
ID Tag Memory Maps Refer to page 159.
The NVASC attribute can be used only with the V700-L22-V2.
With the V700-L22, if the MID data contains non-visible ASCII characters:
s = 0, MID item length = 0, SSACK = “EE” execution error
• Write ID
ID Tag Memory Maps Refer to page 159.

• NVASC = “NOM”
1) If the MID data contains non-visible ASCII characters:
s = 0, MID item length = 0, SSACK = “EE” execution error
2) If the MID data does not contain non-visible ASCII characters:
Normal response
• NVASC = “ALL”
A normal response is returned even if the MID data contains non-visible ASCII characters.
• NVASC = “STD”
1) If the MID data does not contain visible ASCII characters:
s = 0, MID item length = 0, SSACK = “EE” execution error
2) If the MID data contains non-visible ASCII characters:
The non-visible ASCII characters are deleted and a normal response is returned.
• NVASC = “EXT”
1) If the first data in the CID in the range defined by CIDOF and CIDLN is NULL, an “EE” execution error is returned.
2) If there are no visible ASCII characters between the start of the range defined by CIDOF and CIDLN and NULL, an “EE”
execution error is returned.
3) Any non-visible ASCII characters between the start of the range defined by CIDOF and CIDLN and NULL are deleted
and the MID is returned along with a normal response.
• When the specified target is invalid:
s = 0, MID item length = 0, SSACK = “CE” communications error
• If SSACK is not “NO” (normal), the List of Status will be a list structure of 0 items.

• If an MID that is under the length set for the CarrierIDlength attribute is specified, an error occurs and the MID data is not
written.
