Connect Tech Blue Heat/Net Sync User Manual
Revision 0.01 63 63
Protocol Descriptions
The Blue Heat/Net Sync supports a variety of protocols. The following is a brief explanation of
each and how they are implemented.
ARP
Address Resolution Protocol, a method used to find a unit‟s Ethernet MAC address from its
Internet address.
BOOTP
Bootstrap Protocol, a protocol that allows a unit to boot from the network instead of using
information stored on the Blue Heat/Net Sync (typically in Flash memory).
DHCP
Dynamic Host Configuration Protocol, a protocol that provides a means to dynamically
allocate IP addresses to computers on a local area network. The system administrator assigns
a range of IP addresses to DHCP and each client device on the Local Area Network requests
an IP address from the DHCP server. The request and grant process uses a lease concept with
a controllable time period. The Blue Heat/Net Sync offers this as a configurable option; it
can either be turned on or the user can set a fixed IP on the unit.
HTTP
HyperText Transfer Protocol, a standardized Protocol that Web Browsers use to connect to
web pages. It is used to provide web based configuration tools on the Blue Heat/Net.
IP
Internet Protocol, a common addressing scheme for modern networks. Used in conjunction
with TCP to form TCP/IP (see below)
RARP
Reverse Address Resolution Protocol, a method to find a unit‟s Internet address from a MAC
or Ethernet address.
TCP
Transmission Control Protocol, a lossless protocol, requiring a handshake to insure that data
is not lost during transmission. Used in TCP/IP to form the main data transfer pathway
between Blue Heat/Net Sync units and the host computer.
Telnet
A terminal-protocol that can be run over TCP/IP to connect to a remote unit. It is one of the
methods used to configure the Blue Heat/Net Sync unit.
TFTP
Trivial File Transfer Protocol, a protocol used to download firmware to the Blue Heat/Net.
UDP
User Datagram Protocol, a protocol used when handshake is not critical. It is used by TFTP
(see above) and for auto discovery of the units.
