Sabre 1555 RFID & Bar Code Reader Programmer’s Reference Manual
4-22
Not Accepted Command (NAC = 0x15)
NAC is followed by a one-byte parameter indicating the type of problem encountered
(Table 4-18).
Product Version Identification (PVI = 0x16)
The PVI command is used to obtain the P/N and firmware version of the product or a
subpart of the product (Table 4-19).
The syntax is as follows:
<STX> < PVI > < peripheral number > <FM> <CHK> <ETX>
The product response is as follows:
<ACK>
<STX> < ASI > <PVI> < “string” ><FM> <CHK> <ETX>
where “string” format = “board_part_number firmware_revision_number”
For example, “Sabre 1555PDT 2.08C.”
A space character (0x20) is used to separate each field. If the peripheral number does
not exist, a NAC response is returned.
Resend Last Message (RLM = 0x19)
RLM requests that the last message be resent.
