Connect Tech Blue Heat/Net Sync User Manual Introduction Connect Tech‟s Blue Heat/Net Sync allows remote access to synchronous/asynchronous serial devices via an Ethernet LAN or the Internet. Blue Heat/Net Sync network-enables serial communication devices that are designed to be connected to serial ports so that the devices no longer need to be tied to a single computer.
Connect Tech Blue Heat/Net Sync User Manual Understanding Virtual COM Ports In a typical serial port setup, the application communicates directly with the connected serial port hardware. Virtual COM ports differ in that the application communicates with a network protocol layer that transfers the necessary information to and from the remote serial ports.

From the command prompt of your computer, run: route add A.
Connect Tech Blue Heat/Net Sync User Manual Blue Heat/Net Sync Configuration The Blue Heat/Net Sync comprises several software components, each of which manages various functions of the Blue Heat/Net Sync. The following is a breakdown of these components.
Connect Tech Blue Heat/Net Sync User Manual program on a PC). Configuration Data Space (CDS) This is the area, in non-volatile (flash) memory, which stores the configuration parameters. CDS (Configuration Data Space) Description The Blue Heat/Net Sync has a number of configuration parameters which are stored in a nonvolatile (flash memory) area. (See appendix for list of parameters). The CDS area is stored redundantly in the flash memory along with a CRC-style checksum to ensure data integrity.
Connect Tech Blue Heat/Net Sync User Manual SCM (Serial Configuration Manager) Description The Serial Configuration Manager is one of the applications you can use to access the Configuration Data Space (CDS) settings of the Blue Heat/Net Sync. Since the CDS stores the default serial port settings, it is important that the line mode is configured prior to first use. Accessing the ports will not be possible otherwise.

Connect Tech Blue Heat/Net Sync User Manual Common Configuration Setups Static IP Setup In some networking environments it is best to have the IP address set to a fixed value. The advantage is that since it is fixed, connecting to it can be a lot simpler. Static IP is often the best choice if you are trying to connect via WAN or through a Firewall. It can be difficult to resolve the Blue Heat/Net Sync‟s IP address if you use DHCP in this instance. The default configuration is a static IP of 192.168.42.1.
Connect Tech Blue Heat/Net Sync User Manual DHCP Setup In many modern networks IP numbers are not static but are automatically assigned by a DHCP server and can change over time or on each power up. DHCP must be enabled on the Blue Heat/Net Sync because it is shipped to use a default static IP (192.168.42.1) Using SCM Log onto the Blue Heat/Net Sync. The SCM does not require a login. The default password for the SCM is password. Enter net dhcp=yes. This will turn on DHCP on the unit. Enter net dns_ip=3.

Connect Tech Blue Heat/Net Sync User Manual Figure 32: Typical Asynchronous Date Frame Serial Line Interface Tutorial RS-232 Line Interface: RS-232 is the simplest, least expensive line interface standard, the Sipex tranceivers used on the Blue Heat/Net Sync refer to RS232 as V.28 mode. It is also referred to as EIA232 and TIA/EIA232. The RS-232 specification signals levels of +3V to +15V for a logic 0 or Space, and -3V to 15V for a logic 1 or Mark.
Connect Tech Blue Heat/Net Sync User Manual mode RS-485 is fully compatible with RS-422; which is considered a subset of RS-485. The use of differential transmitters and receivers ensures RS-485 communications are reliable and robust. This means two wires are used to transmit or receive a signal. One wire carries the true or non-inverted signal; the other wire carries the inverted signal. The non-inverted signal is labelled with a (+) and the inverted is labelled with a (-).
Connect Tech Blue Heat/Net Sync User Manual Multi-drop 4-Wire, Full Duplex Communications: In a multi-drop 4-wire differntial network, two to 32 devices are connected together. Note that each RS-485 receiver counts as a device or “load”. In this multi-drop mode of communication, a master slave protocol must be enforced, that is, all communication is initiated by the master, in this case a Blue Heat/Net Sync.
Connect Tech Blue Heat/Net Sync User Manual Bus Contention on Differential Multi-drop Networks: Bus contention occurs when two or more devices enabled on a bus attempt to run the bus to opposite logic values. From the diagram above, we can see that there are multiple differential transmitters (TXD) on the bus. To avoid the bus contention problem, the differential transmitter features a tri-state, or high impedance mode controlled by an input pin (enable).
Connect Tech Blue Heat/Net Sync User Manual Termination Resistors in Differential Networks Termination Resistors in Differential Networks: Differential networks often benefit from the installation of termination resistors. Termination is rarely required for lower baud rates, for example 9600 baud or less.
