DescriptionCompact and reliable, the TC1504 Fiber Optic Modem links synchronous data communication equipment requiring RS-422/RS-449 interfaces. It supports synchronous data rates up to 2.048 Mbps with an external clock.
Transparent to the data, the TC1504 combines external clocking and data into an optical composite signal for transmission between local and remote units. It is DCE/DTE switchable.
Diagnostics include local and remote Loopback and visual indicators for power, Receiving Timing, Receive Data, Transmit Timing, Transmit Data, and Optic Sync. DIP switches are provided for the Local and Remote Loopback functions, Slave Clock, and DCE/DTE configuration.
The TC1504 will work with all types and sizes of multimode (850nm/1300nm) or single mode (1300/1500nm) fiber optic cable. Fiber optic connectors are ST or FC. The electrical connector is a male DB37. Power is 9 to 12VDC or 115/230VAC with an external power cube. An extreme temperature version (-20ºC to 70ºC), Model TC1504H, is also available.
