AVs GH655AV GH656AV Description Service Preconfig 2x PWRD RS232 5V/12V Service Preconfig 4x PWRD RS232 5V/12V If you order either AV, the factory will configure the serial port power jumpers so that 12V will be on the DSUB pin 1 and 5V will be on the DSUB pin 9. If you order AV# GH655AV, the TWO serial ports on rp3000 will be configured. If you order AV# GH656AV, FOUR serial ports will be configured for power; however, you must first order the Powered Serial card AV# KH887AA option before selecting this AV since there are only 2 serial ports on the rp3000. Adding the powered serial card provides a total of 4 serial ports. AV# GH656AV can then be selected so all four serial ports are configured for power. Below is a diagram showing the jumper settings for each of these optional preconfigured AV numbers: CAUTION: Always unplug the rp3000 from power when configuring jumpers. rp3000 motherboard: Serial/COM 1 - P16, Serial/COM 2 = P17 Powered Serial Card: Serial/COM 3 - J4, Serial/COM 4 = J5 58 Chapter 6 Removal and Replacement Procedures
