MODEL7211 converter provides easy conversion from ITU-T G.703 E1 channel to Ethernet interface. Can used widely in connecting between WAN and LAN, monitoring, etc. The Ethernet interface is 10/100Mbps auto negotiation and can be full/half duplex. The E1 is transparent and in full rate, which can support the E1 unframed mode, including fractional E1 per request. A pair of MODEL7211 offer a cost effective solution for using existing E1 leased lines for transparent Ethernet service. Local management of the MODEL7211 Converter is provided via DIP switches. Front panel LEDs monitor the G.703 link, Ethernet LAN and serial ports for status and Loss of Sync.

MODEL1100 10/100M adaptive Ethernet optical transceiver can interconvert the electric signal of can interconvert electric signal of 100Base–TX twisted pair and optical signal of 100Base-TX. It extends the network transmission range from 100m to 100Km (single mode optical fiber). Its typical application is Ethernet long range interconnection, such as the interconnection between the equipment room of community with MAN. No configuration of the switch is needed during connection due to the adaptive function. The newly added lightning protection function guarantees the safety of the equipment. Features 1. Choice external or internal power, choice 220VDC or -48VAC 2. Accord IEEE802.3 10Base-T, 100Base-T, 100Base-F standard 3. 10M, 100M adaptive 4. Adaptive full/half duplex 5. Connect optical link and electrical link

The Model277 Series converter is equipped with a multiple interface circuit that can handle RS-232, or RS-422/485 serial interfaces andmulti-mode or single- mode fiber. Model277 converters are used to extend serial transmission distance up to 2 km (multi-mode fiber) or up to 20 km (single- mode fiber). Note that the RS-232 and RS-422/485 interfaces cannot be used on the same Model277 at the same time to convert to fiber.Auto Baud Rate Detection The Model277 Series incorporates a method for automatically detecting the serial signal baud rate by hardware. This is an extremely convenient feature for the user. Even if adevice's baud rate is changed, the signal will still be transmitted through the RS-232 or RS-422/485 to fiber converter without any problem. Features 1. Auto sense serial signal rate, zero delay automatic transmit 2. 500Kbps the highest rate 3. Supply three interface (RS232/485/422) 4. Multi-mode 2KM, signal-mode 20KM
