Model TC1200 RS-232 Async Fiber Modem w/Handshaking                                                  Features     Product or Application Questions (click here)   Async Data Rates Up to 120 Kbps 3 Independent Channels (or 1 Ch. w/Handshaking) 5 Control Signals (RTS, CTS, DTR, DSR & CD) Multimode or Single Mode (850/1300/1550nm) Multiple Diagnostic LEDs Local & Remote Loopback Functions Sturdy Compact Metal Case High Temperature (-20°C to 70°C) Version Optional Description The TC1200 is a 3-channel asynchronous RS-232 fiber optic modem that provides up to five bi-directional control (or handshake) signals (RTS, CTS, DTR, DSR and CD). It offers the versatility of linking three data communications devices over a single duplex fiber or one device with a bi-directional control.  Compatible with both single and multimode fiber, it supports data rates up to 120 Kbps. Six Diagnostic indicators indicate power, electrical signal status and optic sync. It is a DCE device only and performs Local & Remote loopbacks (for diagnostics) with the flip of a switch. Because the TC1200 can also function as a 3-channel multiplexer by using the control signal channels as data channels, this benefit makes the TC1200 particularly cost effective. An extreme temperature version (-20°C to 70°C), Model TC1200T, is also available.
