Additional information:

Due to different customer systems and configurations, the serial communication and functionality needs to be revised. The difference between hwA and hwB is regarding flowcontrol of comports when set to RS422. The table below shows the difference:

hwA (previous products):
- Transmit is always enabled in RS422
- Does not support RS422 bus mode

hwB (current products):
- RTS has to be set HIGH to enable transmit in RS422
- Supports RS422 bus mode

hwC (future products):
- Jumper to change between hwA and hwB
- Supports RS422 bus mode

RTS (Request To Send) is a RS232 signal used for flowcontrol.

Solution:
In future revision Jakob Hatteland Display will implement hwC which will enable customers to choose between hwA and hwB functionality; and thus widen our product functionality towards customer needs. This revision is currently under development, and a final effective implementation date is not yet set.
