    Depending on the option you ordered, you should find (in addition to this manual) the following items inside the shipping container: ä ä ä ä ä PCL 840 with Opt 8B • One PCL-840 8-port RS-232 card • One 1.5 m DB-62 to DB-62 cable • One RS-232 connection box •...
  • Page 13 It should be free of marks and scratches and in perfect working order on receipt. As you unpack the PCL-840, 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-840 card. Align the hole in the retaining bracket with the hole on top of the expansion slot.

  • Page 15: Card Configuration

    Card Configuration The PCL-840'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 16 Default Factory settings for the PCL 840 • I/O address: 1st port 0x180 2nd port 0x188 3rd port 0x190 4th port 0x198 5th port 0x1A0 6th port 0x1A8 7th port 0x1B0 8th port 0x1B8 • Configuration Access Port (CAP): 0x180 •...
  • Page 17 For example, if the PCL-840 is to be installed under SCO UNIX system as the primary (or first) eight port board, you can designate the PCL-840'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 18 The PCL-840's driver determines the configuration of the installed cards by reading a data file, GEN DRV.CNF. When you first install the PCL-840, 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 19 After the screen shows up, move the cursor bar (using the arrow keys or the mouse) to the PCL-840 field and press ENTER. The screen shown below will appear. Setup Here you can set the configuration for each of the PCL-840 cards installed in the system.
  • 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-840 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.
