MASTER CARD: INPUTS AND OUTPUTS NUMBERING

We are going to define the numbering for inputs and outputs when we connect 4 Master cards via USB Expansion card. The connection diagram and the connectors identification is:

For each Master card, J1 is the bus where displays card is connected. J2 and DB9 are the outputs connectors, J3 and J4 are the inputs connectors.

For the first master card, the numbering would be:

  DB9

For the rest of cards, we have just to add to every value the number of inputs (72) and outputs (64) available in one Master card.

Master 1:

• J2: 11 to 48
• DB9: 49 to 55
• J3: 00 to 35
• J4: 36 to 71

Master 2:

• J2: 75 to 112
• DB9: 113 to 119
• J3: 72 to 107
• J4: 108 to 143

Master 3:

• J2: 139 to 176
• DB9: 177 to 183
• J3: 144 to 179
• J4: 180 to 215

Master 4:

• J2: 203 to 240
• DB9: 241 to 247
• J3: 216 to 251
• J4: 252 to 287
