Contemporary Controls is offering true Ethernet media converters that have been upgraded. "The EIMC family takes advantage of new components allowing the company to achieve better cost factors, an enhanced manufacturing technique to minimise production time, and automated testing to provide reliable products at less cost to our customers," explains Joe Stasiek, sales manager.
Stasiek says the EIMC is a true media converter, converting signals between copper and fibre without any Ethernet frame store-and-forward; therefore the data experiences minimal latency.
"This product can operate in a transparent mode allowing the fibre-optic connection to be transparent to the copper ports they are interconnecting," he says. "In this manner, the link status of the copper ports truly reflects the status of each end copper port. True media converters are very important in RSTP networks. If a store-and-forward media converter (or switched media converter) is used, this can create long recovery times or cause broadcast storms to occur."
These products are built to route traffic in harsh RF/EMI environments and to expand distances up to 2 km with multimode fibre and up to 15 km with single-mode fibre. Their rugged, DIN-rail mount design will operate in a 0 to 60°C temperature range with extended voltage.
The models support full- or half-duplex mode. The EIMC-10T/F can operate at 10 Mbps and convert 10Base-T to 10Base-FL (850 nm) or it can operate at 100 Mbps and convert 100Base-TX to 100Base-SX (850 nm). Two models pass 100-Mbps data between 100Base-TX and 100Base-FX (1300 nm) multimode segments: the EIMC-100T/FT and the EIMC-100T/FC. The EIMC-100T/FCS is used for 100 Mbps (1300 nm) single-mode networks.
Two front panel DIP switches set the operational mode, allowing for greater flexibility - full-duplex, half-duplex or transparent. Each unit will auto-negotiate data rate and duplex with its copper partner in transparent mode, but only the data rate will be negotiated in either the half- or full-duplex mode. There is no auto-negotiation on the fibre side. The fibre port settings are slaved to what is negotiated on the copper side.
Several LEDs are provided for convenient front panel diagnostics. The Power LED glows green when power is applied. Each port has two LEDs. The green Port Activity LED flashes with activity while the link LED indicates the data rate by colour: green for 100 Mbps and yellow for 10 Mbps.
