The above picture shows all the connectors used for making external connections to the CC18. These are:<\/p>\n\n\n\n

Bidirectional digital I\/O 0-3, 4-7, 8-11 and 12-15<\/h6>\n\n\n\n

There are four 6-pin connectors for 16 I\/O points which can each be used as an input or an output. Each connector has 4 signal pins as well as connection to the positive supply voltage and to 0V (common, ground). The wiring for these is detailed separately elsewhere for\u00a0input mode<\/a>\u00a0and\u00a0output mode<\/a>.<\/p>\n\n\n\n

Analog<\/h6>\n\n\n\n

This 4-pin connector is for connecting to the two analog inputs. In addition to the two actual analog input pins the connector has +5V and 0V brought out to facilitate using potentiometers or ratiometric sensors.<\/p>\n\n\n\n

Power<\/h6>\n\n\n\n

This 3-pin connector is for applying power to the CC18. The wiring is described under\u00a0CC18: Power supply<\/a><\/p>\n\n\n\n

Comms.<\/h6>\n\n\n\n

This is the connector you connect to for programming the CC18. This is NOT an RS232 connector. A PC232 programming cable adaptor is required for connecting to a PC for programming.<\/p>\n\n\n\n

SPx<\/h6>\n\n\n\n

The SPx expansion scheme is documented\u00a0elsewhere<\/a>\u00a0in the SPLat Knowledge Base. This connector is for expansion boards like the\u00a0XBIO16<\/a>.<\/p>\n\n\n\n

X1-X2<\/h6>\n\n\n\n

Xwire<\/a>\u00a0bus connections. The two connectors are identical and wired in parallel. The lefthand pin as shown is 0V (ground). The righthand pin is bidirectional serial data.<\/p>\n\n\n\n

A1\/A0<\/h6>\n\n\n\n

Configuration jumpers setting the\u00a0Xwire<\/a>\u00a0address. If you are not using Xwire you can read these using the\u00a0XwireGetJumpers<\/a><\/code>\u00a0instruction and use them in your program for selecting user options.<\/p>\n","protected":false},"excerpt":{"rendered":"
