W&T Centronics > Serial Interfaces Interface Centronics > RS232, Model 28000 Function The W&T-Interface 28000 allows uni-directional connection of peripherals equipped with an RS232 port to the parallel port on a computer. Setting the Interface Before first using, the RS232 parameters for the interface need to be set using the DIL switches inside the Interface housing. The baud rate, data format and handshake procedure need to be set to the values which the connected peripheral uses.
W&T Centronics > Serial Interfaces Pin assignments for the RS232 interface The RS232 interface is implemented as a DB25 male with DTE configuration. The pin configuration is shown in the following table: pin# funktion 2 data output (TxD) 3 XON/XOFF input (RxD) 5 handshake input (CTS) 7 signal GND Pin assignments for the Centronics interface The RS232 interface is implemented as a 36-pin Centronics female. The pin configuration is shown in the following table: pin# 1 2..9 strobe data 0 ..
W&T Centronics > Serial Interfaces Connecting the Interface The Interface has a Centronics input and an RS232 output. Centronics interface The Centronics input of the Interface corresponds in its wiring and signal characteristics to the input of a parallel printer. This means that any normal printer cable permitting connection of the data source with a Centronics printer can be used to connect the Interface input to the data sender.
