As you unpack the PCL-846/847, 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-846/847 card. Align the hole in the retaining bracket with the hole on top of the expansion slot.
  • Page 14 The ports on the PCL-846/847 card have jumpers and DIP switches which require configuration before the card is used. DIP switches set the port I/O addresses and speed modes. Jumpers set the port IRQs. The board is shipped with default settings. If you need to change these settings, however, see the following sections.
  • Page 15 Next, you will need to select an I/O base address, and port IRQ (interrupt request) numbers for the PCL-846/847 . The card base address can be set using the DIP switches on the card. The DIP switch labelled "MODE 1" will set the card to standard or enhanced mode, as shown below.
  • Page 16 In the enhanced mode, the card base address is set by the user. Select an address which is not already being used by another card in the system. If you are installing more than one PCL-846/847 card in your system, set the cards to different base addresses. DIP switches on S1 control each card's base address, as shown below.
  • Page 17 The switch sum is set to 2F8: 200 + 80 + 40 + 20 + 10 + 8 (HEX). Note: On the PCL-846/847, the address line A9 does not appear on the DIP switch, as it is permanently hardwired to hex 200.
  • Page 18 JP14 Select an IRQ which is not already in use by another card in the system. If you are installing more than one PCL-846/847, set them to different IRQ numbers. Jumper Bank JP11 controls the card IRQ. Simply place the jumper on the desired interrupt level as shown in the following figure.

  • Page 21 The PCL-846/847 employs a unique speed option that allows the user to choose either normal speed mode (1x) or high speed mode (8x). This high speed mode is selected using switch S1. To select a baud rate commonly associated with COM ports , such as 2400, 4800, 9600.
  • Page 22 Otherwise, the driver output will remain in high impedance status. If a jumper is set to "ON," the driver is always enabled, and always in high or low status. The user must select a mode before beginning RS- 422 applications. PCL-846/847 User's Manual...
  • Page 24 The PCL-846/847's driver determines the configuration of the installed cards by reading a data file, GEN-DRV.CNF. When you first install the PCL-846/847, 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.

Set the IRQ, base address, baud rate, 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.
