MODEL LT1200

Asynchronous RS-232 Modem w/Full Handshaking

Model LT1200

  • Async Data Rates up to 128 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
  • Applications

Typical applications include linking remote terminals or printers to host computers, tail circuits to existing multiplexers and extending data communications links. Fiber Optic Modems are also ideal for connecting data communications devices in harsh manufacturing or outdoor environments where EMI or RFI interference, ground loops and lightning are prevalent.

Description

Pocket Rocket modems are designed for local and campus networks up to distances of approximately 5km multimode and 80km single mode. Distances can vary depending on the size and type of fiber optic cable, number of connections and type of fiber optic connectivity device(s) used in a given network.

The LT1200 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 128 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 LT1200 can also function as a 3-channel multiplexer by using the control signal channels as data channels, this benefit makes the LT1200 particularly cost effective.
