Product Description

The Model 227
RS-232 High Speed Line Driver with LCD Display provides full duplex transmission from DC to 115.2 KBPS over two twisted pairs. The Model 227 includes Telebyte's unique DataSpy LCD display, which provides the user with important status information regarding the operation of the device. This LCD operates from less than one milli-watt of power thereby not affecting the operation of the Model 227. The LCD is extremely useful during the installation and checkout and whenever there are suspected problems. 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. The Model 227 does not require any power source since it steals its power from the Transmit Data signal applied to the RS-232 connector. The data I/O occurs on Pins 2 and 3 of the RS-232 connector. The DTE/DCE switch allows reversing of the connections to Pins 2 and 3 depending on whether the unit to which the modem is connected is wired as a DTE or DCE device. Data transmission between modems utilizes differential baseband signaling techniques. Common mode signal rejection capability is greater than 20 volts. These features provide for error free operation in noisy environments. The Model 227 is offered with a female RS-232 connector. The four wire line interface is a five-position terminal block and an RJ-11 modular phone connector. The four-wire line includes built-in surge protection which uses pin 1, Frame Ground, as the path for suppressing surges.
