TECH NOTE: Model 200 DB-37 Expansion I/O Connector - AVIDdirector-M2M

The following is a definition of the Model 200's I/O Expansion Connector. It brings out the console TTL (Serial0), RS-232 (Serial1), TTL Serial that was used for the RJ-12 on the Model 100 (Serial2), and TTL1 to TTL18. TTL7 to TTL18 where used for the HVC1 to HVC4 lines on the Model 100.

The analog pins read 0V to +5V with 12 bit accuracy.

The I/O Expansion board brings the TTL1 to TTL18 lines to a Phoenix connector and provides access to the Serial2 (TTL20-TTL23) and I2C via the I/O Expansion connector. I2C is also available on J5. Here is a schematic of the I/O Expansion board ExpansionIO.pdf and the ExpressPCB files are in IO_Board.zip.
