2.4.6 External Alarm Port (J8) - DB9 (F) [IO Board Version 001]
An external alarm port is provided to allow maximum flexibility of configurations. This
allows the user to interface with the alarm output of other equipment into the RCP
controller. Inputs are protected against ESD of ±15 kV using the Human Body model;
against ESD of ±8kV using the Contact Discharge method specified in IEC1000-4-2;
and against ESD of ±15 kV using the Air Gap method described in IEC1000-4-2. Table
2-5 shows the external alarm pin-out.
2.4.7 Ethernet Port (J9) - RJ45 (F)
This is a RJ45 connector with integrated magnetics and LEDs. This port becomes the
primary remote control interface when the Interface option is selected to “IPNet” as
described in Section 7.6.2.2. This feature allows the user to connect the RCP to a
10/100 Base-T office Local Area Network and have full-featured Monitor & Control
functions through a web interface. See Table 2-6 for Ethernet pin outs.
Note: IP address, Gateway address, Subnet mask, IP port and IP Lock
address all need to be properly selected prior to first use (see Appendix B
for details).
LED lamps on the connector indicate network status. A steady Green light indicates a
valid Ethernet link; a flashing Yellow LED indicates data transfer activity (on either the
Transmit and Receive paths).
