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,JP3,JP4,JP5 (Jumper 2,3,4,5)  

      Set for RS232 RTS&CTS loopback only.

    JP2,JP3,JP4,JP5

  SW1 (Switch 1)

      Identifies card number.
Under the RS485 mode, all the RS485 Ports are set to receive mode automatically, while one port use to send data to the other port, it needs to set RTS signal to 1, to enter driver mode, then send message or dat. After sending message, it needs to set signal to 0 to enter receive mode again.

1. Select High Speed or Normal Speed Mode

        JP1

                  

The JP1 is 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 PCI BUS 4 CHANNELS RELAY OUTPUT / 4 CHANNES PHOTO ISOLATOR INPUT 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).


¡EThe card number starts from 0 to 15.
