TXA IF OUT Connector (J7) The TXA IF OUT connector (J7), is a type N, female connector
used to route the transmit IF signal (70 or 140 MHz) to
KST-2000A/B Unit A, IF INPUT. From the system TX IF IN port
(J12). Nominal impedance 50Ω, unbalanced.
TXB IF OUT Connector (J8) The TXB IF OUT connector (J8), is a type N, female connector
used to route the transmit IF signal (70 or 140 MHz) to
KST-2000A/B Unit B, IF INPUT. From the system TX IF IN port
(J12). Nominal impedance is 50Ω, unbalanced.
RXA IF IN Connector (J9) The RXA IF IN connector (J9) is a type N, female connector used
to route the received IF signal (70 or 140 MHz) from KST-2000A/B,
Unit A IF OUTPUT to the system RX IF OUT (J11). Nominal im-
pedance is 50Ω, unbalanced.
RXB IF IN Connector (J10) The RXB IF IN connector (J10) is a type N, female connector used
to route the received IF signal (70 or 140 MHz) from KST-2000A/B,
Unit B IF OUTPUT to the system RX IF OUT (J11). Nominal im-
pedance 50Ω, unbalanced.
RX IF OUT Connector (J11) The RX IF OUT connector (J11), is a type N female connector used
to connect the RX IF signal (70 or 140 MHz) from the online
KST-2000A/B down converter to the modem. Nominal impedance
is 50Ω, unbalanced.
TX IF IN Connector (J12) The TX IF IN connector (J12), is a type N, female connector used
to route the 70 or 140 MHz IF signal from a modem, through an IF
splitter to each of the KST-2000A/B IF input of the up converters.
Nominal impedance is 50Ω, unbalanced.
3.5 Indicators Description
TX A Online Indicator The TX A online indicator is a weatherproof, green LED that illumi-
nates when uplink A is online, and extinguishes when uplink A is
offline.
TX B Online Indicator The TX B online indicator is a weatherproof, green LED that illumi-
nates when uplink B is online, and extinguishes when uplink B is
offline.
RX A Online Indicator RX A online indicator is a weatherproof, green LED that illuminates
when downlink A is online, and extinguishes when downlink A is
offline.
RX B Online Indicator The RX B online indicator is a weatherproof, green LED that illumi-
nates when downlink B is online, and extinguishes when downlink B
is offline.
