CO4011 Application with Co4011 RS232 adapter with a Cable and a D-Sub-Connector to PC (Com X) MAX232 D-Sub 9 VSS 21 VCC VCC VCC VCC VCC 18 ID0 Jy Jx 1k 1k 4k7 4k7 25 2 3 8 7 6 4 5 ID1 26 OVL# OVL# RXD (TTL) TXD (TTL) 60 IN10 IN10 62 To enable the programming condition chose an identifier that forces the Pins ID0 and ID1 to low level. For example identifiers ID= 3, 7, 0x0B, 0x0F … might be used. Close the jumpers Jx and Jy. For optimised programming adapter design, the programming adapter should close the jumpers Jx and Jy directly by plugging the adaptor into the application board. For normal operation mode the programming adapter must be removed. |
