This is done via JP6 and JP5. Table 5-11: COM2 RS-232/422/485 setting (JP3, JP4. * RS-232 RS-422/485 2 1 2 1 JP3 JP4 2 6 1 5 2 6 1 5 JP4 JP3 6 5 6 5 * default setting Table 5-12: COM2 RS-232/422/485 setting (JP5. * RS-232 RS-422 RS-485 246 246 246 135 135 135 * default setting The IRQ and the address ranges for COM1, 2, 3, and 4 are fixed. However, if you wish to disable the port or change these parameters later you can do this in the system BIOS setup. The table overleaf shows the default settings for the panel PC’s serial ports. PPC-120/140 User's Manual COM1 and COM2 are one set. You can exchange the address range and interrupt IRQ of COM1 for the address range and interrupt IRQ of COM2. After exchanging, COM1's address range is 2F8 ~ 2FF and its request IRQ is IRQ3: and COM2's address range is 3F8 ~ 3FF and its interrupt IRQ is IRQ4. COM3 and COM4 are another set. Their selectable function is the same as the COM1/COM2 set. Table 5-13: PPC-120/140 serial port default setting.

The board has two connectors to support these displays simultaneously; one for standard CRT VGA monitors and one for flat panel displays. CRT display port information can be found in Section 3.9 - VGA Port. The pin assignments for the flat panel display connector, backlight connector and other related connectors are described in the appendices. 5.4.1 LCD panel power setting (JP6) The panel PC's’s PCI SVGA interface supports 5 V and 3.3 V LCD displays. By changing the setting of JP6, you can select the panel video signal level to be 5 V or 3.3 V. Table 5-16: Panel VCC setting (JP6. * 5 V 3.3 V 123 1 1 23 * default setting Configuration of the VGA interface is done exclusively via the software utility. You do not have to set any jumpers.

This is an invaluable protective device for standalone or unmanned applications. Setup involves one jumper and running the control software. (Refer to Appendix B.) 5.5.1 Watchdog activity selection (JP15) When the watchdog timer activates (i.e. CPU processing has come to a halt), it can reset the system or generate an interrupt on IRQ11. This can be set via jumper JP15 as shown below: Table 5-18: Watchdog activity selection (JP15. * System reset IRQ11 3 13 2 2 1 1 * default setting Chapter 5 Jumper Settings and Connectors PPC-120/140 User's Manual 6 PCI Bus Ethernet Interface This chapter provides information on Ethernet configuration. • Introduction • Installation of Ethernet Driver -Installation for MS-DOS & WINDOWS 3.1 -Installation for ...
