Product information:

The OM-10B modem transmits and receives serial asynchronous and synchronous data over a pair of optical fibers. The interface can be set to EIA530, EIA530A, RS232, or RS485. The modem is data rate transparent from DC to 128K Baud. Data, two clocks, and all hand-shake lines are passed across the link. There are two models of the OM-10B, a DCE and a DTE. The OM-10B-DCE connects to Data Terminal Equipment such as a computer. It has an onboard bit rate generator which outputs standard clock frequencies, if a clock is desired for synchronous communication. The OM-10B-DTE connects to Data Communication Equipment such as a modem.

Switches on the side of the OM-10B are used to select any of the following interfaces: EIA-530, EIA-530A, RS-232, EIA-485 -2 wire. The modems will work with different interfaces at each end. For instance, one end may be configured as EIA-530 and the other as RS-232.
