<STX>
(Hex code 02) is used to mark the beginning of a string of message characters to be transmitted.
For paging message types of 1 to 4 Beeps (defined by the ‘T’ character above), this character
and all following characters are ignored by the paging transmitter, until another
<SOH>
is
encountered.
This character may have one or no leading commas separating it from the cap code.
X...X
A string of 0 to 256 alphanumeric message characters to be transmitted. For paging message
types of 1 to 4 Beeps, this character and all following characters are ignored by the paging
system, until another
<SOH>
is encountered.
<ETX>
(Hex code 03) is used to mark the end of a string of message characters to be transmitted. For
paging message types of 1 to 4 Beeps, this character and all following characters are ignored by
the paging system, until another
<SOH>
is encountered.
<EOT>
(Hex code 04) is used to mark the end of a Transmit Paging Message command string. All
following characters are ignored by the paging system until a
<SOH>
character is encountered.
<CR><LF>
(CR is Hex code 0D, LF is Hex code 0A)
These characters are ignored by the paging system unless contained within a message string
and are used only for formatting output on a PC.
The
<CR>
and
<LF>
characters are optional.
Example 1:
<SOH>A,5,46180,<STX>This is a test<ETX><EOT><CR><LF>
Will send the message “
This is a test
” at 512 bps to an alphanumeric pager with cap code 0046180.
Note:
The POCSAG alphanumeric character set is the entire ASCII 7 bit character set.
Example 2:
<SOH>N,5,0765155,<STX>412-3433<ETX><EOT><CR><LF>
Will send the message “
412-3433
” at 512 bps to a numeric pager with Cap Code 0765155.
Note:
The POCSAG numeric character set allows Hyphen
( - )
, space, left bracket
( [ )
, and right bracket
( ] )
characters in
addition to the normal numeric character set.
Example 3:
<SOH>N1765155<STX>412-3433<ETX><EOT>
Will send the message “
412-3433
” at 1200 bps to a numeric pager with cap code 0765155.
