    The PCM-3618 is a PC/104-compatible module with eight individually configurable RS-422/485 ports. It works with PC/104 CPU modules to extend additional RS-2422/ 485 ports. The PCM-3618 also features lots of functions such as high transmission speed of 921.6 kbps, shared IRQ and more. It also provides high-performance 16C550 UART communication chip with 16-byte FIFO to reduce CPU load.

    You can use this package to return the card if it should need repair. Board Layout Card Configuration Each port on the PCM-3618 card requires configuration prior to use. The DIP switches set the port to the appropriate I/O address (SW2) and different modes (SW1). The jumpers set the port's IRQ.

    Jumper and Switch Settings The PCM-3618 supports ENHANCED mode and SHAREDIRQ functionality. It can fully meet your application needs for high speed and multiple ports. The detail of spe- cific settings are described as follows: Enhanced Mode (M0) In enhanced mode, you can select a different base address. The base address deter- mines the address for each port.
  • Page 15 Independent IRQ Mode Interrupt Status Register Setup (SW1, Vector Address) This feature on the PCM-3618 is utilized in the shared IRQ. When data arrives at one of the eight ports, an interrupt will be generated in the interrupt register. The PC soft- ware can read this, and identify immediately which port generated the interrupt.

  • Page 18 Speed Selection The PCM-3618 employs a unique speed option that allows the user to choose either normal speed mode (1x) or high speed mode (8x). Speed mode is selectable at SPEED ofSW2. Normal Speed To select the baud rate commonly associated with COM ports, such as 2400, 4800, 9600? 115.2Kbps, place the switch as follows.

    The PCM-3618's driver determines the configuration of the installed cards by reading a data file, GEN-DRV.CNF. When you first install the PCM-3618, 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.
