Chapter 2: SETUP Inspection Your 3PCIOSD1x serial card was tested for proper operation before shipment. It should be in perfect mechanical and electrical condition upon receipt. The card is normally pre-configured for RS-232 operation. The data clock speed is set by one jumper to x1 (normal) operation or to x4 operation. The operating mode of the card is set using 8 jumpers: 4 jumpers select RS-232 operation or RS-422/485 operation, one jumper sets RTS for RS-232 & RS-485 modes or Send
