9.3 SDxP Packet
The packet is broken up into 2 parts: the Header and the Payload
Header
The header is used to carry general information, such as is shown in the C
programming structure below:
typedef struct { eType
type; char[21]
uName; char[21]
password; uChar
desc;
uChar param;
uint16 seq;
} THeader
Variable Description
type Enumerated type that tells the SDxP server what type of packet is being sent. See the Types
subsection for a full list of packet types.
uName This variable MUST contain a valid user on the target Axess Elite.
password This variable MUST contain the password for the specified user.
desc This variable is the type descriptor that describes the type of data that is being sent. By
extension, it lets the server know what the payload is. There is a different set of descriptors for
each type class. See the Descriptors subsection for a full list of descriptors by type.
param Reserved for future use. Optional parameter that may be passed to the server in addition to the
descriptor.
seq The packet’s sequence number. Used as part of the security scheme.
Payload
The payload is determined by a combination of the type class and the descriptor. The payloads are described by
the descriptor; see the Descriptors subsection for details.
