EDIATec ECW100 Manuale di installazione
7.1. Power (Pin 1, 5)
During flight operations at least Pins 1 and 5 must be connected.
There must be a direct electrical connection between ECW100 and the aircraft
battery. This connection must be via a 1 AT fuse. Essential electrically-operated
flight instruments must not draw their power through ECW100 fuse. It must be
possible for the pilot to interrupt the power supply to ECW100 during flight by
means of a switch or circuit breaker without affecting other essential aircraft
systems. This might be necessary if the pilot suspects that ECW100 may be
interfering with another on-board system, the suspected presence of smoke,
the smell of smoke, or flying in a country where the use of ECW100 is not
permitted.
In spite of reverse polarity protection, it is important to check for correct
polarity during installation; in particular the power supply and data wires must
not be interchanged.
After switching on and the self-test routine, the unit must first capture satellite signals to
establish position. Even if the antenna has a clear view of the sky, this process can take
a few minutes. For this reason a glider tug pilot should leave ECW100 switched on during
brief waiting periods between flights. During night flights ECW100 must be switched off.
7.2. GPS Test (Pin 3, 6, 7, 8)
The GPS test is not for customers use.
7.3. Serial Data RS-232 (Pin 11, 12, 13)
In normal configuration Pin 12 transmits the most important NMEA-0183 Version 2.0
compatible GPGGA and GPRMC codes at a configurable data rate (see document "Data
Port Specifications"); also Garmin proprietary PGRMZ codes with barometric altitude
information. Further codes are provided for third party applications (e.g. external
displays). These are described in a separate document "Data Port Specifications". This
document also describes how ECW100 software may be configured.
The power for external displays can be connecting to Pin 9 (+3 V).
7.4. Intercom / Head set (Pin 14, 15)
In motor airplane the warning sound can connect to an intercom, radio or head set. It's a
standard AC signal with max. 1 V.
