Function Bit: The Function Bit is the single hex character following the preamble.
This character tells the Transmitter which bit to turn ON in the POCSAG
message sent. Characters are:
(Hex 01) Non Priority Alert for Numeric Pagers.
(Hex 02) Priority Alert for Numeric Pagers.
(Hex 03) Non Priority Alert for Alphanumeric Pagers.
(Hex 04) Priority Alert for Alphanumeric Pagers.
Cap Code: Cap Code is a seven digit data string which contains the address
information of the Pager to be used.
Cap Code Prefix: Is the first 3 digits of the Cap Code. ONLY Cap Code Prefixes
of 000 and 008-199 are allowed. If the first 3 digits of the Pagers cap code are
[000], the Transmitter will convert the last 4 digits (Pager number) of Cap Code
by multiplying by 8.
Example: Cap code information sent to the Transmitter = [0000111].
The Transmitter sends to the Pager address [0000888].
If the first 3 digits of the Pagers cap code are not [000], the Transmitter will
send the Cap Code information as sent.
Example: Cap code information sent to the Transmitter = [1230111].
The Transmitter sends to the Pager address [1230111].
Separator: A separator is used between the Cap Code and the message sent . It
supplies information as shown in the table.
Messages:
Alphanumeric Pagers can be sent a maximum of 120 alpha characters
(using separator Chr$(02) orChr$(0A)).
Numeric Pagers can be sent a maximum of 16 numeric characters (using
separator Chr$(0B) or Chr$(03)).
Glowster and CommPass use message characters as controls.
Example: To send default alert three to a Glowster or CommPass,
send the hex string to the Transmitter: FF FF FF 01 3P 3P 3P 3P 3P
3P 3P 03 0D] where PPPPPPP is the 7 digit Pager number. See Cap
Code for more information.
Example: To send a alert, other than the default, send the hex string
to the Transmitter [FF FF FF 01 3P 3P 3P 3P 3P 3P 3P 03 3A 3A 0D]
where PPPPPPP is the 7 digit Pager number and AA is the alert.
