Data Comm for Business, Inc. (DCB), a leader in manufacturing innovative data communications equipment since 1981, announces their new EMB-2 Modbus Gateway. This new ethernet to serial Modbus gateway connects serial RTUs running Modbus protocols to a Modbus/TCP host. The Ethernet side of the gateway communicates at 10 or 100Mbs using 10/100BaseT, and the serial side uses either RS-422/485 or RS-232 in point-to-point mode, or RS-485 2-wire in multi-point mode. The unit contains two serial ports, so the interfaces may be mixed, or multiple strings of RTUs run from a single gateway.

Data Comm for Business, Inc. (DCB), a leader in manufacturing innovative data communications equipment since 1981, announces their new EtherBridge asynchronous Ethernet bridge. This new bridge connects mission-critical LANs over most any asynchronous wide area network. Its applications range from security and traffic control to financial transactions, process industries and SCADA applications. Read the announcement here.

Under constant scrutiny by local public utility commissions, independent system operators (ISOs) throughout the country must, first and foremost, ensure the fail-safe reliability of their operations. Without the continuous up-to-the-second monitoring and analysis of field data, ISOs cannot carryout their mission as arbiter and guarantor of the electric grid upon which its constituents rely.

Although our new location is only about 10 miles away, we not only have a new address, but the mail is delivered from another town... so the address changes, the phones change, but the confusion is becoming a thing of the past. New contact information is on the web here.

Conitel uses a 31 bit long data word, instead of the common 10 bits for ASCII asynchronous data. DCB's new product development will allow Conitel protocol, the ulitimate older style protocol (legacy) to operate over a modern and cost effective frame relay network.

Why convert the old Conitel equipment to frame relay networks? Because it is very cost effective. The alternatives include changing out an entire SCADA system which can cost up to $50,000 per location when a new computer system, a new RTU and all the labor is tallied up. And staying with the old analog phone lines may cost 20% to 50% more than frame relay lines.

The DCB BPF is the answer for migrating Conitel, Racal-Redac, Modbus, DNP, and other SCADA systems to frame relay. DCB has all the pieces. The DSU's, 202T modems and the BPF FRAD. Call or email for more information.
