Product Description
The Model 225 RS-232 Transformer Isolated Multi-Drop Line Driver with LCD Display provides the capability of supporting a multi-drop environment typically used in polled networks using controlled carrier. This feature can be strapped constantly on or it can be controlled by the Request-To-Send, RTS, signal. The Model 225 operates at any data rate up to 19.2 KBPS with a range of 4 miles. DTE/DCE switching allows the Model 225 to operate in all configurations. The Model 225 incorporates line coupling transformers to provide isolation between communicating modems and protection against AC and DC surges on the four wire line. The Model 225 is available with either a male or female DB25 connector. The Model 225 includes Telebyte's unique DataSpy LCD display, which provides the user with status regarding the operation of the device. The LCD aids during the installation and checkout. The graphic display presents the user with live status of the transmit and receive data signals, TD and RD, and control signals, CTS, RTS, DSR, DCD and DTR.
