I am unable to get the Arium ML4100 to output anything on the RS-232 port. I have tried a direct connection and a Null-Modem connection to no avail. I know that the input port is working as I can get data from the 9010 just fine with the same configuration. Anyone have a working Arium and has used the serial port successfully?<br><br>

&gt;Okay, a checksum on a single byte of FF yeilds an FF<br>
&gt;<br>
&gt;I found this to be interesting......<br>
&gt;<br>
&gt;<br>
&gt;Byte 0 = F3&nbsp; Sig = FE<br>
&gt;Byte 1 = 3E Sig = 1EE8<br>
&gt;Byte 2 = 00&nbsp; Sig = 1EE8<br>
&gt;Byte 3 = ED Sig = 225A<br>
&gt;Byte 4 = 47&nbsp; Sig = 56B6<br><br>
Byte 12 = ?? Sig =910E<br>
Byte 13 = 00 Sig = 20F6<br><br>
<br>
&gt;<br>
&gt;It isn't using the last read byte as the divisor is it?<br>

&gt;&gt;&quot;Rom Signature is a four-digit HEXADECIMAL number that is a shorthand<br>
&gt;&gt;representation of the data obtained in an area of ROM memory. The ROM<br>
&gt;&gt;signature is obtained by successively dividing the data in ROM by a binary<br>
&gt;&gt;number (they DON't say what the @!$%#$@% number is! - JR). The resulting<br>
&gt;&gt;signature identifies the data from which it is obtained, and provides a<br>
&gt;&gt;convenient way of&quot; (....blah blah, no other description of the process).&quot;</blockquote><br><br>
