Ask for return address before sending back, I will change adress 2016-08-30.
Please send out the units 2-3 at a time. As soon as they are ready.
RS232 serial communications
Please note that devices with dual WBO2 (and old devices) have NFET on EC18/pin17 (2nd WBO2 heater), not GND as most new devices.
- That means RS232 connection with GND only on EC18/17 (RS232 GND not connected to EC36/26) will fail to communicate, or worse: sometimes communicate, but unreliably. (eg. communicate with engine off, but frequent comm disconnects with engine running).
