The pin configuration of thisheader is as follows:Figure 40: Pin Configuration of Header J74.4: Header J6The Header labeled J6 is used for interfacing the EVB over UART to a second PCBwhich has the Host microcontroller mounted. This header bypasses the DB9connector and the 3.3V-5V level shifter ICs and a simple ribbon-cable can beused for this interface. This header can be enabled/disabled by flipping theswitches SW4 and SW5. The pin configuration of this header is as follows:Figure 41: Pin Configuration of Header J64.5: Switches SW4 and SW5The Switches SW4 and SW5 are used to select between the DB9 connector andthe Header J6 for the UART interface. In the images of the EVBs shown above,the switches are placed (to the right on the RS9110-N-11-22/24 EVB and to theleft on the RS9110-N-11-26/28 EVB) to enable the DB9 connector. If they areflipped, the Header J6 is enabled.Redpine Signals, Inc. Proprietary and confidential Page 44 |
