FLEX Message Word Definitions
FLEX CAPCODES
In order to send messages to a FLEX decoding device, the FLEX service provider
must know the device’s address, the address type (single-phase, any-phase, or
all-phase), the address’s assigned phase, the address’s assigned frame, and the
address’s battery cycle. This information is typically included in a FLEX CAPCODE.
The assignment of CAPCODEs is regulated to prevent duplication of addresses on a
system. Check with your FLEX service provider or other appropriate regulatory body
for FLEX CAPCODE assignments. The following paragraphs describe what these
parameters define.
The device address consists of one or two 21-bit words. A one-word address is called
a short address, while a two-word address is called a long address. Address words
are separated into ranges according to the following table
