MD-63 RS-422/485 Fiber Modem
The MD-63 can be used for point to point communication between equipment with RS-422/485 interfaces. Fiber optic cable is completely immune to external interference, which makes this unit ideal for harsh industrial environments. Another reason may be the need for a high level of security as fiber optic cable is very hard to tap. The MD-63 can handle data rates up to 1.5 Mbit/s and is available both in a multi- and single mode fiber version.
