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). ---- Unit number: 4130 belongs to Engdahl/RBD Damaged LM1815. Unknown reason. Also some unsure funktion of some parts. Test everything. Please change it, or change is to Hall if not possible without board replacement. ---- Unit number 11658. Belongs to Engdahl Brand new unit.
