2.2 DESCRIPTION
The B&B Model 1140 miniature dual fiber optic modem brings
fiber to the desktop. Combining the inviolability of fiber with the
troubleshooting capabilities of V.52 and V.54 diagnostics, the Model
1140 is the best choice for your most critical RS-232 links. The
Model 1140 operates async. or sync., supports data rates to 38.4
Kbps and plugs directly into a workstation's RS-232 port. Like all
fiber optic modems, the Model 1140 is inherently immune to
RFI/EMI noise, ground loops and transient surges. The carrier may
be switch selected as either "Continuously On" or "Controlled by
RTS". The RS-232 connector is configured as DCE.
Two easy-to-read LED indicators monitor the Error and Test
modes. Drawing all necessary power from the RS-232 interface, the
Model 1140 requires no AC power or batteries to operate.
Measuring only 3.42" x 2.10" x .73", the Model 1140 is able to fit into
tight installation spaces. On the RS-232 side, the Model 1140 comes
equipped with either a male or female DB-25 connector; on the fiber
side it is available with a choice of SMA or ST connectors.
