# psion_pccard_network
### 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
