VECTOR PACKET
The Vector Field follows the Address Field in the FLEX protocol. Each Vector Packet must be matched to its
corresponding Address Packet. The ID of the vector packet is the word number where the vector word was
received in the frame. This value corresponds to the
WN
bits sent in the associated address packet. The phase
information in both the Address Packet and the Vector Packet must also match. It is important to note for long
addresses, the first message word will be transmitted in the word location immediately following the associated
vector. See
"
Message Building
"
on page 59 for a message building example. In this case, the word number
(identified by
b
6
to
b
0
) in the Vector Packet will indicate the message start of the second message word if the
message is longer than 1 word.
There are several types of vectors - 3 types of Numeric Vectors, a Short Message / Tone Only Vector, a Hex /
Binary Vector, an Alphanumeric Vector, a Secure Message Vector, and a Short Instruction Vector. Each is
described in the following pages. One of the modes of the Short Instruction Vector is used for assigning
temporary addresses that may be associated with a group call.
The Numeric, Hex / Binary, Alphanumeric, and Secure Message Vector Packets have associated Message Word
Packets in the message field. The host must use the
n
and
b
bits of the vector word to calculate what message
word locations are associated with the vector. Both the message word locations and the phase must match.
Four of the vectors (Hex / Binary, Alphanumeric, Secure Message, and Short Instruction) enable the S5T8701 to
begin the all frame mode. This mode is required to allow for the decoding of temporary addresses and / or
fragmented messages. The host disables the All Frame Mode after the proper time by writing to the decoder via
the All Frame Mode Packet. See
"
Building a Fragmented Message
"
on page 61 and
"
Operation of a Temporary
Address
"
on page 64 for more information. For any Address Packet sent to the host (except tone-only
addresses), a corresponding Vector Packet will always be sent. If more than two bit errors are detected (via BCH
calculations, parity calculations, check character calculations, or value validation) in the vector word the e bit will
be set and the message words will not be sent.
