  • Page 27 You can attach up to two floppy disks to the PCM-4890's on-board controller. You can use any combination of 5¼" (360 KB and 1.2 MB) and/or 3½" (720 KB, 1.44 MB, and 2.88 MB) drives. A 34-pin daisy-chain drive connector cable is required for a dual- drive system.
  • Page 28 DB-25 connector. The cable has a 26-pin connector on one end and a DB-25 connector on the other. The PCM-4890 supports one parallel port. The port is designated as LPT1 and can be disabled or changed to LPT2 or LPT3 in the system BIOS setup.
  • Page 29 The PCM-4890 can drive an 8 W speaker at 0.5 watts. Ensure that alternatives to this specification do not overload the card. The front panel LED indicator for hard disk access is an active low signal (24 mA sink rate).
  • Page 30 The PCM-4890 offers four serial ports: three RS-232 and one RS- 232/422/485. These ports let you connect to serial devices (a mouse, printers, etc.) or a communication network. The serial port connectors are mounted on the right hand side of the card.
  • Page 31 IRQ5/10 COM4 IRQ5/10 The PCM-4890's SVGA interface can drive conventional CRT displays and is capable of driving a wide range of flat panel displays, including electroluminescent (EL), gas plasma, passive LCD and active LCD displays. The card has two connectors to support these displays, one for standard CRT VGA monitors and one for flat panel displays.
  • Page 32 The PCM-4890 provides a bias control signal on CN2 which can be used to control the LCD bias voltage. It is recommended that the LCD bias voltage not be applied to the panel until the logic supply voltage (+5 V) and panel video signals are stable. Under normal operation the control signal (ENAVEE) is active high.
  • Page 33 The PCM-4890 is equipped with a high performance 16-bit Ethernet interface which is fully compliant with IEEE 802.3 10Mbps CSMA/ CD standards. It is supported by all major network operating systems and is 100% Novell NE-2000 compatible. Configuration of the Ethernet is very easy and can be done via the RSET8019.EXE program included on the utility disk.
  • Page 34 10BASE-T connects to the PCM-4890 via an adapter cable to a 10- pin polarized header (CN13). For 10BASE-T RJ-45 operation, an adapter cable converting CN13 into a standard RJ-45 jack is required. The Network Boot feature can be utilized by incorporating the Boot ROM image files for the appropriate network operating system.
  • Page 35 An on-board watchdog timer reduces the chance of disruptions which EMP (electro-magnetic pulse) interference can cause. This is an invaluable protective device for standalone or unmanned applications. Setup involves two jumpers and running the control software (refer to Appendix A). You can enable or disable the watchdog timer by reading the I/O ports with your program.

  • Page 73 The PCM-4890 is equipped with a watchdog timer that resets the CPU or generates an interrupt if processing comes to a standstill for whatever reason. This feature ensures system reliability in industrial standalone, or unmanned, environments.
  • Page 74 Jumpers J19 and J20 control the watchdog settings. The default configuration of the timer is enabled with system reset. To enable the watchdog timer, you must write a program which reads I/O port address 443 (hex) at regular intervals. The first time your program reads the port, it enables the watchdog timer.
