Page Center User Manual
Page 24
After initiating a page, and receiving the ID= prompt, the Entry Device can respond in one of two different
ways. One way puts the PAGE CENTER into an Automatic Mode, and the other ways puts it into a Manual
Mode.
Automatic Entry of a Page
Entry Device
PAGE CENTER Action
Comment
<ESC>PG1<CR>
The Entry Device tells the PAGE CENTER transmitter that it
wants to automatically send a POCSAG page by ending this
sequence.
<CR><ACK><CR>
or
<CR><NAK><CR>
or
<ESC><EOT><CR>
The PAGE CENTER will respond within one second of the
ACK sequence signifying that the Entry Device has
successfully logged on to the PAGE CENTER. If paging
entries cannot be accepted, it will respond with the NAK
sequence or the ETX sequence, which should force the Entry
Device to disconnect.
<ESC> [p <CR>
This "go ahead" sequence tells the Entry Device that it is OK
to go ahead and send over the information for the first page
or pages. The p is always the lower case "p".
<STX>
PagerID<CR>
Message<CR>
<ETX>
Checksum
<CR>
This Pager/Message Sequence Block tells the PAGE
CENTER the ID (the Pager Number in the PAGE CENTER's
database) of the pager this the Message is to be sent to. The
checksum is computes as shown later in this document. The
total number of characters sent from the Entry Device per
sequence should not exceed 255.
Repeat the above
Pager/Message
Sequence Block as
many times as
required, if more
pages are to be sent.
<EOT> <CR>
When the Entry Device does not want to send any more
pages, it sends this EOT sequence, to tell the PAGE CENTER
that it is finished with this automatic session.
Pages Accepted
<CR>
or
Invalid Page
Entered<CR>
or
<Message><CR>
One of these status messages will be returned at the end of
the session. They are for information purposes only.
<CR><RS><CR>
This is only sent if there was an error in this session,
probably due to an invalid pager ID or a message type
mismatch.
PAGING EXCHANGE
DISCONNECT <CR>
<ESC> <EOT>
The End of Transaction message sent from the PAGE
CENTER to the entry device, telling it to disconnect.
