Page 8: Description
The number of ICs is decreased, allowing for a compact half-size board. The switchless and jumperless design allows the PCL-749 to be easily configured via software. To meet the next generation require- ment of high-speed transmission, 16C550 FIFO UARTs are used. -

Page 12: Initial Inspection
It should be free of marks and scratches and in perfect working order on receipt. As you unpack the PCL-749, check it for signs of shipping damage (damaged box, scratches, dents, etc.). If it is damaged or it fails to meet specifications, notify our service department or your local sales representative immediately. -

(save the screw to secure the interface card retaining bracket). Remove the anti-vibration card clamp if supplied. 6. Carefully grasp the upper edge of the PCL-749 card. Align the hole in the retaining bracket with the hole on top of the expansion slot. -
Page 14: Card Configuration
Card Configuration The PCL-749's advanced design eliminates the hassles with switches and jumpers during card configuration, making it ideal for industrial applications that require low MTTR. Instead, the card is configured entirely through the included easy-to-use setup software. Type IO IRQ at the DOS prompt and follow the on-screen instructions. - Page 15 Default Factory settings for the PCL 749 • I/O address: 1st port 0x180 2nd port 0x188 3rd port 0x190 4th port 0x198 • Configuration Access Port (CAP): 0x180 • IRQ channel: 10 (shared by four ports) Since there is no visual indication of the card's configuration address port (CAP), you may not be able to execute the configuration software if you forget the CAP.
- Page 16 For example, if the PCL-749 is to be installed under SCO UNIX system as the primary (or first) eight port board, you can designate the PCL-749's I/O base to 0x280, IRQ to 4 and interrupt vector to 0x2C0 by simply selecting SCO UNIX (Arnet Compatible) on the menu.

Page 17: Driver Installation For Dos Users
The PCL-749's driver determines the configuration of the installed cards by reading a data file, GEN DRV.CNF. When you first install the PCL-749, and each time you change the card's address and IRQ, you will need to run the card setup program to save the settings to the configuration file. - Page 18 Driver selection screen After the screen shows up, move the cursor bar (using the arrow keys or the mouse) to the general serial board field and press ENTER. The screen shown below will appear. Setup screen PCL 749 User's Manual...
- Page 19 Here you can set the configuration for each of the PCL-749 cards installed in the system. Set the IRQ, base address, baudrate, buffer size and port number to match the card's configuration. Do this by moving the highlight to the field you want to set up. Press ENTER and a menu will appear, allowing you to select the correct setting.
- Page 20 If any of your ports have the same setup, you can define them all at one time by pressing F5 to bring up the Group Setup screen shown below. Group Edit menu When you are finished setting up the ports, press the ESC key to return to the previous windows.
- Page 21 – you do not have to install it in the CONFIG.SYS file. To install the PCL-749 card driver change to the directory or floppy disk containing the driver files and type GEN-DRV. You should soon see the following message: PC ComLIB Serial Communication Driver (Ver x.xx)
- Page 22 Programming The following code fragment illustrates how the library functions can simplify card programming, reducing setup time and avoiding bugs. The following C program shows a simple data transfer test. It uses a PC-ComLIB function call to send data between Port 1 and Port 2 at a rate of 57.6 Kbps.

Windows 3.1 provides a versatile and easily configurable interface that supports up to four COM ports with a standard driver. The PC-ComLIB Standard Windows COMM Driver, along with PCL-749, allow users to install up to six serial ports under Windows 3.1. - Page 24 COM1 (0x3F8, IRQ4), while designating COM2-5 on IRQ3 for the four ports on a PCL-749 card. Note: If using a serial mouse, it must be installed on either COM1 (0x3F8, IRQ4) or COM2 (0x2F8, IRQ3), and must have its own dedicated IRQ.
