Page 5: Function
W&T RS232 Multi Computer Adapter RS232 Multi Computer Adapter, Model 85603 The W&T RS232 Multi Computer Adapter 85603 permits a bi-directional connection of two serial data sources to a peripheral device. Automatic switching between the two senders is done on a time-controlled basis: The data sender that wants first to output something automatically blocks the outputs from the other source. -
Page 6: Mechanical Features And Enclosure
Wiring assignments The RS232 ports A and B are implemented as SUB-D female connectors with DCE pin functions, and port C as a SUB-D male connector with DTE pin functions. This design ensures that the T-switch can be wired into the majority of applications with standard 1:1 cables. - Page 7 W&T RS232 Multi Computer Adapter The pinout for the individual ports can be found in the follo- wing tables. RS232 input Port A and B with DCE pin functions: Pin# Function Signal Direction always "on" output data out output data in...

Page 8: Display And Control Elements
W&T RS232 Multi Computer Adapter Display and control elements The device uses four LEDs, a green „Power“ for indicating correct supply voltage and the LEDs marked „A“ and „B“ to indicate which input channel is active. The LED marked „Error“ indicates the presence of parity or framing errors in running data traffic and can only be cleared explicitly by pressing the „Clear“... -
Page 9: Configuring The Serial Ports
W&T RS232 Multi Computer Adapter Configuring the serial ports All three ports on the T-switch can be configured for transmission rate, data format and handshake procedure completely independently of each other. This feature allows you to connect the T-switch to terminal devices which use different serial data formats. -
Page 10: Serial Format
W&T RS232 Multi Computer Adapter Serial format Baud rate, number of data bits and any parity bit which may be used can be configured separately for each port on the T-switch, so that the format can be adapted to any connected terminal device. -
Page 11: Setting The Format - Dil Switches
W&T RS232 Multi Computer Adapter Setting the format - DIL switches The DIL switch banks SW1, SW2 and SW3 have the same scope of functions for all three ports: the individual switches determine the transmission speed, the number of data bits, the parity and the handshake procedure of the respective port. -
Page 12: Modes
W&T RS232 Multi Computer Adapter Modes The RS232 Multi Computer Adapter model 85603 offers two operating modes, which are described in the following. In all operating modes two LEDs on the front panel of the Multi Computer Adapter are used to indicate which of the two available data paths is currently active. -
Page 13: Transparent Mode
W&T RS232 Multi Computer Adapter Transparent mode The data sender that wants to send something first is immediately connected to the serial terminal device. All data received on the other input of the T-switch are rejected as long as the terminal device is connected to the first data sender. -
Page 14: Diagnostic Functions
90 milliseconds 120 seconds 500 milliseconds Diagnostic functions Starting up an RS232 port is often accompanied by difficulties, since both the pin assignments as well as the transmission parameters need to agree in order to enable errorless data transmission. The RS232 Multi Computer Adapter 85603 has a settings dump function integrated that allows you to check the configuration, which can be quite useful during installation. - Page 15 After releasing the key the port set on the DIL switches SW4.3 and SW4.4 generates the following output: PU 40,6000;;SI 0.2,0.3;DT LB RS232 MULTI COMPUTER ADAPTER, 0MBYTE LB VERSION 1.x TRANSPARENT MODE (TIMEOUT MODE) LB PORT A: BAUD...
