PCMCIA 1 Port RS232 CHAPTER 2 INSTALLING IN YOUR COMPUTER Installing the Card This card is hot plug compatible it may be inserted into your pcmcia type 2 slot when the machine is either off or powered on. Please refer to your machine user guide for detailed instructions on inserting a PC card. Chapter 2 Page 5

CHAPTER 3 SOFTWARE INSTALLATION Introduction. This section describes the software installation procedure allowing the PCMCIA 1 port RS232 to be configured within the Windows 95, Windows 98, Windows Millenium and Windows 2000 operating systems. Windows 95 Installation Insert the card into an available type2 socket. This can be done even if the machine is powered ON. If installing from a "power off" condition Windows 95 should then load normally. During the booting process, Windows 95 will detect the card and briefly display a message box indicating the detection process. Windows will then display the "Update Device Driver Wizard", requesting insert any disk which came with the card. Insert the Serial Solutions CDROM installation disk or the Serial Solutions floppy disk into an appropriate drive and click 'Next'. Chapter 3 Page 6

This can be done even if the machine is powered ON. If installing from a "power off" condition Windows 98 should then load normally. During the booting process, Windows 98 will detect the card and briefly display a message box indicating the detection process. Windows will then display the "Update Device Driver Wizard", requesting insert any disk which came with the card.

Settings available in this window are: Baud Rate. Data Bits. Parity. Stop Bits. Flow Control. Change to suit remote device. Restore Defaults - When clicked, this will reset the selected port to the default values of: Baud Rate: 9600 Data Bits: 8 Parity: None Stop Bits: 1 Flow Control: Xon / Xoff Maximum Baud Rate Setting These settings allow access to the faster data rates available on this card. The faster rates are not enabled by default for compatibility purposes. The faster data rates are only available directly from your application if it uses the standard Windows dialogue for serial port settings. Baud Rate Multiplier This enables applications that do not use the standard Windows serial port configuration dialogue to access the faster data rates. e.g. with this option enabled, an application which selects 115,200 baud will actually set the hardware to the fastest possible rate of 921,600 baud. In other words the baud rate is multiplied by a factor of 8. Chapter 3 Page 18

Windows 2000 Installation Insert the card into an available type2 socket. This can be done even if the machine is powered ON. If installing from a "power off" condition Windows 2000 should then load normally. During the booting process, Windows 2000 will detect the card and briefly display a message box indicating the detection process. Windows will then display the "Found New Hardware Wizard", requesting insert any disk which came with the card.

PCMCIA 1 Port RS232 RS232 Pinouts & Port Cabling CHAPTER 4 RS232 PINOUTS AND PORT CABLING. Introduction. This chapter gives details of the 9 and 25 pin RS232 pin outs, cabling and connections, with information on how to connect the serial ports of two PCs and how to make a selftest loop back connector. The RS232 Standard. The RS232 standard is ancient in computer industry terms. Introduced in 1962, it is now widely established. RS232 is a slow, short distance, single ended transmission system (i.e. only one wire per signal). Typical RS232 maximum cable length is 50 feet with a maximum data rate of 20K bits per second. Figure 4-1. RS232 Point To Point Connection. TTL D R TTL Ground Ground RS232C Standard 1 Driver 1 Receiver Line Length Max Data Rate 50 Feet = 15m 20 Kbits/sec Chapter 4 Page 33

PCMCIA 1 Port RS232 RS232 Pinouts & Port Cabling Serial Port Pin Outs. The pinouts of the 9 and 25 pin Male D connectors are given below. Figure 4-2. Serial Port RS232 Pin Outs. PIN 6 - DATA SET READY (DSR) PIN 7 - REQUEST TO SEND (RTS) PIN 8 - CLEAR TO SEND (CTS) PIN 9 - RING INDICATOR (RI) PIN 1 - DATA CARRIER DETECT (DCD) PIN 2 - RECEIVED DATA (RXD) PIN 3 - TRANSMITTED DATA (TXD) PIN 4 - DATA TERMINAL READY (DTR) PIN 5 - GROUND (GND) 9 Pin connector: 25 Pin connector: PIN 20 - RING INDICATOR (RI) PIN 22 - DATA TERMINAL READY (DTR) PIN 2 - TRANSMITTED DATA (TXD) PIN 3 - RECEIVED DATA (RXD) PIN 4 - REQUEST TO SEND (RTS) PIN 5 - CLEAR TO SEND (CTS) PIN 6 - DATA SET R EADY (D SR) PIN 7 - GROUND (GND) PIN 8 - DATA CARRIER DETECT (DCD) 9 Pin D Serial Port RS232 Cables. To connect to the AT style RS232 Serial Port like those found on the PCMCIA 1 Port card you will need a cable terminating in a 9 way female D connector. It is sound practice to use cables with screws fitted that will allow you to fasten the cable securely to the PC card. In general, you will need to make up a "cross over" cable to correctly interface the PC to the RS232 port of another computer or device. Traditionally, making up the cross over cable has been Chapter 4 Page 34

PCMCIA 1 Port RS232 RS232 Pinouts & Port Cabling considered a black art. However, provided you have the pin outs and handshake requirements of both sides of your RS232 connection, the cross over cable becomes a matter of common sense. The cross over cable is simply to ensure that the right signals going out of one RS232 port go into the appropriate lines of the other RS232 port. 9 Pin D Serial Port Connection To Another PC. Suppose we want to connect the AT style 9 pin D Serial Port to the serial port of another IBM PC. See Figure 4-3. 1) Connect the earth lines. Line 5 of Serial Port 2 to lines 1 & 7 of the other PC. This gives the two devices a common earth level. 2) Connect the Transmit and Receive lines together. Line 3, TXD, Port 2 goes to line 3, RXD, of the other PC. Line 2, RXD, Port 2 goes to line 2, TXD, of the other PC. This allows each to receive data transmitted by the other. 3) Connect the Port 2 DTR line, pin 4 to the other PC DCD, pin 8 and CTS, pin 5, lines. Also, connect up the other PC DTR line, pin 20 to the Port 2 DCD, pin 1 and CTS, pin 8, lines. This allows the receiving device to signal when it can no longer accept data. The receiving device sets DTR false when it is unable to receive any more data. The sending device reads DTR on its CTS and DCD pins. It should stop sending when CTS goes false. 4) Connect the Port 2 RTS line, pin 7, to the other PC DSR line, pin 6. Also, connect the other PC RTS line, pin 4, to the Port 2 DSR line, pin 6. This RTS line is used to let the other device know that it is ready for data exchange. Figure 4-3. 9 Pin D Serial Port To Other PC Cable. Chapter 4 Page 35

PCMCIA 1 Port RS232 RS232 Pinouts & Port Cabling 9 Pin D Serial Port To A Modem. If you are connecting a MODEM to a 9 pin D Serial Port then you will NOT need a cross over cable and a straight through cable connected as the 9 to 25 pin adapter given in Figure 4-5. 9 Pin D Serial Port Loop Back Connector. A loop back connector can be used to echo RS232 data transmitted by a serial port back into its own RS232 receiver. In this way, the function of the serial port can be tested. For an AT style Serial Port use the a female 9 way connector wired as in Figure 4-4.
