Configuration of the FLEX
CAPCODE
8.6.1
G
ENERAL
A CAPCODE specifies a decoder address, the collapse
value of the address and whether single-phase, any-phase
or all-phase address. The PCD5008 supports
single-phase and any-phase operation. The FLEX
protocol provides a standard mechanism to derive phase
and frame in which an address should be transmitted.
If this mechanism is not used, a CAPCODE also specifies
the phase and frame assigned to the address.
8.6.2
CAPCODE
FORMAT
The FLEX
CAPCODE consist of a series of decimal and
alphabetic fields, see Fig.16 for the field definitions.
When the FLEX
standard pager collapse value of 4
(battery cycle of 16 frames) is used, the pager collapse
field can be omitted.
The collapse value is a number between 0 and 7 and
defines how often the decoding device looks for messages
on the FLEX
channel. For a given collapse value b, the
decoding device looks in every 2
b
frames. Thus an
address with an assigned base frame of 3 and a collapse
value of 5 typically looks for messages in frame 3 and
every 32 frames thereafter (i.e. frames 3, 35, 67 and 99).

field, represents the frame number if
standard frame and phase
embedding rules are not used.
Roaming capability, optional
alphabetic character 'P'
indicates no roaming capabilities.
Pager collapse (battery cycle),
optional 1 digit decimal field
(mandatory if frame number
field is included) indicates pager
collapse value.
Address field, mandatory 7, 9 or 10 digit
decimal field, contains the information from
which the BCH address codewords for this
CAPCODE are derived.
CAPCODE type, mandatory
alphabetic character, indicates rules
for deriving phase and frame from
address field.
