2.1.2.10a Hardware Mute (Tx Enable)
There are three ways to mute the amplifier via hardware input:
1) A 50 ms closure to ground on Port J7, Pin 17 to toggle between Mute/Unmute
states;
2) Select from the front panel Main Menu: 4.Fault Setup → 2. Auxiliary Faults →
1.Action → 4.Alert+Mute. Then select 4.Fault Setup → 2.Auxiliary Faults → 2.Fault
Logic → 2.Fault on Low. A continuous closure to ground on Port J7, Pin 18 will then
mute the amplifier. See
Section 2.2.4.2
;
3) Select from the front panel Main Menu: 4.Fault Setup → 2. Auxiliary Faults →
1.Action → 4.Alert+Mute. Then select 4.Fault Setup → 2.Auxiliary Faults → 2.Fault
Logic → 2.Fault on High. A continuous open to ground on Port J7, Pin 18 will mute
the amplifier. See
Section 2.2.4.2
.
2.1.2.11 Link Port (J8)
The 9-pin male connector J8 Link Port is used to link a SSPA with other units in a
redundant system in order to pass online/standby status information between them.
Leave unconnected unless specified otherwise. This connector is discussed further in
Section 4.1.4
and
Section 5.5
.
2.1.2.12 Ethernet Port (J9)
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 7.8
. This feature allows the user to connect the SSPA to a
10/100 Base-T office Local Area Network and have full-featured Monitor & Control
functions through a web interface. See
Table 2-4
for Ethernet pin outs.
Note: IP address, Gateway address, Subnet mask, IP port and IP Lock
address needs 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).
