### PC Card Adapter Flow
|
|
|
|
Psion --> rs232 --> max3243cai --> ttl --> Siemens CAB C165 LF --> PCMCIA
|
|
|
|
### Notes
|
|
* The C165 does not have hardware flow control pins (just rx/tx) so must bit-bang the flow control.
|
|
* The cable has 10 pins and is socketed - looks like molex
|
|
* Cable wires:
|
|
* Black (sheathed)
|
|
* Blue
|
|
* Brown
|
|
* Red
|
|
* White
|
|
* Yellow
|
|
* Black
|
|
* Green
|
|
* Orange
|
|
* Red/White
|
|
* Looks like there are 2 extra wires in the cable that aren't used and cut down.
|
|
|
|
### ToDo
|
|
* Identify wires
|
|
* First will just continuity test against the max3243
