The Boltek BGW312 Ethernet Serial Server allows an EFM-100 and/or LD-250 to be remotely located any distance from the display computer using Ethernet to relay the data. Adding a long-range Wi-Fi Ethernet bridge also makes wireless operation possible up to several miles.

LD-250 and/or EFM-100 data flows over Ethernet as if it was connected directly to your PC.


The BGW312's COM1 connector has been optimized for the EFM-100's EFA-10 fiber optic adapter, providing sufficient port power for the adapter. The COM2 connector is available to connect to the LD-250.
