    Alternatively, it is possible to synchronise units by means of communications, using the GE-LOCAL communications software, or manually by means of the MMI. If the IRIG-B input is used it has priority over time setting by communications, since the time read by IRIG-B is much more accurate.

    Gate 1 (PORT 1 and PORT 2 connectors) and 2 (PORT 3 connector) are independent and the unit can serve them simultaneously. The communications protocol is the same as that used for the rest of the GE digital protection systems and requires the use of the GE-LOCAL software. The instruction book for this program, which facilitates dialogue with the relay, is supplied with the unit.
