It depends on the digit numbers for ASCIIof the data part.Try to make the length of the message sent from the GT different from the length of the response to thereadout command sent from the external device, to enable to distinguish them according to the length.Phone: 800.894.0412 - Fax: 888.723.4773 - Web: www.clrwtr.com - Email: info@clrwtr.com
