Installation

The alarm relay is rated to 220VDC or 2ADC or 60W maximum. The alarm connections provided at the power
connections are a duplicate of the those available via the junction box and described in section 4.4.
A chassis ground stud is provided on the rear panel of the transceiver. Note that the transceiver chassis is
isolated from the incoming power supply so this stud must not be connected to power supply ground.

PC data connection
A 9 way D-type connector is provided on the rear panel of the
Smarter Track Class A
transceiver. This
interface allows direct connection to a PC RS232 interface and can be used for installation, diagnostics or
external display connection. The default configuration for this interface allows connection of an ECDIS or
charting system and duplicates the ‘External display’ port in the junction box.

The pin allocation for the 9 way D-type socket on the rear panel of the transceiver is shown in Table 7.
