Page 3: Chapter 1: Introduction
Chapter 1: INTRODUCTION The 232BRC acts as a translator between devices with incompatible asynchronous serial communications. Each port uses a dedicated UART and includes a 16 kbyte receive buffer. Each port can be independently configured for data rate, data format, and handshaking. -
Page 4: Checklist
Checklist Examine the shipping carton and contents for physical damage. If damage is found, file a claim with the shipper immediately. The following equipment should be in the shipping carton: 1. RS-232 Baud Rate Converter model 232BRC 2. Instruction Manual 3. -
Page 5: Chapter 2: Operation
Chapter 2: OPERATION Each port receives data from its connected device, buffers the data, and sends it out the opposite port when that port’s handshaking indicates it is ready to receive data. Each port is set to match the requirements of its connected device through the setup software. -
Page 6: Port Connections
Software(XON/XOFF) Handshaking: Each port can be independently configured for software handshaking. Software handshaking is normally used in communications links where the main data stream is one way, such as to a printer. The main sending device is expected to hold off its data when it receives the XOFF(13 Hex) character, and resume sending when it receives an XON(11 Hex). -
Page 7: Led Indicators
LED Indicators The 232BRC has three LED indicators. The first, labeled “POWER” indicates that power is applied to the converter. The other two, labeled “PORT A BUFFER” and “PORT B BUFFER” indicate that data is present in that port’s receive buffer. Note that the buffer LEDs indicate buffered data only. -
Page 8: Chapter 3: Setup Software
Chapter 3: SETUP SOFTWARE Introduction The 232BRC comes with simple setup software for configuring the A and B ports. The software can run on any PC compatible computer using Microsoft Windows 95, 98, NT, or 2000 operating system. Once the ports are configured, all parameters are saved in non- volatile memory so the 232BRC can be powered down and used anywhere without the loss of configuration data. -
Page 9: Setup Tutorial
Setup Tutorial Step 1: Start the software by double clicking the 232BRC Setup icon on the desktop. Step 2: Select the serial (COM) port that will be used to configure the 232BRC. Step 3: Connect the 232BRC Port A to the PC COM port selected. Install the setup jumper, and power up the 232BRC. -
Page 10: Final System Installation
Step 4: Connect the 232BRC to be copied to the serial (COM) port of the PC. Install the setup jumper. Apply power to the 232BRC. Step 5: Click Next. Step 6: Select Save As from the File menu. Save the configuration to disk. -
Page 11: Appendix A: Cable Charts
Appendix A: Cable Charts All charts give full pinouts. Only pins 2 & 3 are required for basic operation. Pins 7 and 8 are needed for hardware (RTS/CTS) handshaking. If the connected device requires DTR or DSR, these signals are available on pins 4 and 6 respectively. See Appendix B for a block diagram of the 232BRC. - Page 12 Chart A.6.
