422lp9r driver

Model LP9R is a port-powered two-channel RS to RS converter. It converts TD and RD RS lines to balanced RS signals. The unit is powered from the RS handshake lines DTR and www.doorway.rug: driver. Model LP9R is powered from the RS handshake lines DTR and RTS. One of these handshake lines must be asserted (high) in order to power the unit. (See Table 1). The RS driver is enabled when RTS is asserted. RTS must be asserted in order to transmit data. The RS receiver is always enabled. If DTR. to control the driver, Model BBLP9R can be used as an RS to RS 4-wire converter. To ensure reception, it is recommended that DTR is asserted. In order to maximize the amount of power available to the RS driver, the RS handshake lines are not looped back (tied together). As a result, the following handshake.

RS is a point-to-point serial communications standard that defines a differential (or balanced) interface using two separate wires for each signal. Differential signals on twisted pair cables allow very high data rates in environments despite electrical noise and varying ground potentials. Model LP9R is a port-powered two-channel RS to RS converter. It converts TD and RD RS lines to balanced RS signals. The unit is powered from the RS handshake lines DTR and RTS. One of these handshake lines must be asserted (high) in order to power the unit. DTR is always asserted and the RTS is used to control the driver, the LP9R can be used as a RS to RS 4-wire converter. To insure reception, it is recommended that DTR is asserted. In order to maximize the amount of power available to the RS driver, the RS handshake lines are not looped back (tied together). As a result the following handshake lines will appear as disasserted (low): CTS, DCD, and DSR.
