CHAPTER 5
SWITCH AND JUMPER SETTING

The Plug and Play features let hardware configuration for IRQ and I/O address is detected by BIOS automatically, so that it need not switch and jumper setting. However if you need change RS422 or RS485 mode, you need set the jumpers, the on board switch also can be used to identify card number by the users (if you do not set the switch, the PnP BIOS will assign card number automatically).

JP1 (Jumper 1)      Select high speed mode or normal speed mode.

JP2 (Jumper 2)      Select high-speed mode or normal speed mode.

SW1 (Switch 1)       Identifies card number.

1. Select High Speed or Normal Speed Mode

        JP1    

The JP1 and JP2 are used to select high-speed mode or normal speed mode; the clock is 7.3728MHZ for high speed mode, and 1.8432MHZ for normal speed mode. For high speed mode, the baud rate speed up to 460K.

 2. Card Identifier

The switch is used to identify card number, default setting is card 15 , and there are two methods to set the card number:

•  PnP mode

Just plug in PCCOM PCI bus 2 port adapter into PCI slot, the PCI BIOS will allocate I/O address to each adapter automatically and assign card number start from 0 to each adapter. You may set any card number at PnP mode, and you need use software tools to distinguish port id. Almost all of the operating systems run at PnP mode.

•  Manual mode

Set card number by card identifier switch, the PCI BIOS will assign pre-allocated I/O address to each adapter. Please set different card number to each adapter (do not duplicate card number setting).
