AlphaSense "FF" models expect incoming data to have a special format.

Below is the format for data strings arriving at the AlphaSense serial or network interface port. Each sub-string will not have any specific length limitation, as AlphaSense will parse the string and allocate memory dynamically. The overall length should be kept under 275 characters currently, and don't forget to keep the message content length within any limits imposed by the wireless messaging provider being used (some are as short as 80 characters). AlphaSense will deliver very long messages, but the provider may either truncate them, or simply not deliver them at all!

Here's the format for incoming data, and description:
(Firmware Ver. 5.0 and up see Note below - you have additional features)

&aaa..._bbb..._ccc...<CR>

& - the "start-of-block character, (ASCII code 38 decimal)

aaa... - phone number to access alpha paging system, including any

PBX prefix, dialing code, etc.

_ - "delimiter character" the underscore character.

bbb... - the destination wireless device(s) ID or PIN number

_ - delimiter character

ccc... - the message content to appear on the wireless device(s)

<EOB> - a character used to denote end-of-block or "end of message"

This EOB character may be selected by the user through the AlphaSense "FF" models Initial Setup Menu. Enter it at the prompt that reads "Incoming End-of-Block Character). The value is defaulted to the "carriage return" (CR) character (ASCII code 13 decimal). A table of codes for other characters may be found here.
