Nera C is a successor of "Nera C12". Nera C is a communication system of
Nera C12

1.2 Configuration
1-2
1.2 Configuration
To use the cable other than TP5FBAW-5DFBB, optional N-TNC converting cable is
needed to both the antenna unit and the terminal unit.
Fig.1.2.1 Nera C system configuration

1.3 Connection
1-3
1.3 Connection
1.3.1 Antenna and terminal unit
The antenna unit, IC-115 and terminal unit, IC-215 are connected by the coaxial cable.
This coaxial cable includes 1530.0 MHz to 1545.0 MHz receiving RF signal, 1626.5
MHz to 1646.5 MHz transmitting RF signal, 1575.42 MHz receiving GPS RF signal
and the power supplied to the antenna unit. The transmitting voltage is +29 V DC and
the receiving voltage +7 V DC.
The loss of the coaxial cable is about 10 dB at 1.6 GHz.
To use the cable other than TP5FBAW-5DFBB, optional N-TNC converting cable is
needed to both the antenna unit and the terminal unit.
Fig.1.3.1 Connection of antenna unit and terminal unit
1.3.2 [Junction] port
[Junction] port is connected to the junction box (IC-315).
Fig.1.3.2 Connecting to Junction Box

1.3 Connection
1-4
1) Connecting the distress alert received unit and ALAM unit
The distress alert received unit: IC-305 and up to 3 ALARM units: IC-306 are
connected to port #1 to #4 in parallel. The electrical rating of port #3 and #4
(TD/RD-A/B) connecting line is RS-485. Each unit needs to be set for identification
such as DIS, RCV-1, 2 and 3. And IC-305 and IC-306 are controlled by the setting of
“Command Window” in [F8]-2: system menu. Terminal unit communicated to these
units recognizes each unit by this setting.
2) Connecting NAV data (IEC-61162)
Ports #6 and #7 (TD-A/B) are used for transmitting NAV data. To transmit NAV data,
optional GPS receiving board (GN-79) is needed.
Ports #8 and #9 (RD-A/B) are used for receiving NAV data. The external GPS data
needs to be connected.
3) Connecting DMC-5
Ports #11 to #15 are DMC-5 connecting terminals. The electrical rating is C. Loop.
DMC-5 is controlled by the setting of “Command Window” in [F8]-2: system menu.
Note) RS-485
This is like RS-422 (balanced). It is half-duplex, and not just point-to-point but like
Ethernet since all devices (nodes) on it share the same “bus”. The driver output signal
level (loaded minimum) is +/-1.5 V.

1.3 Connection
1-5
1.3.3 [LAN] port
10Base-T, RJ-45 connector is used for Ethernet LAN. Terminal unit includes the mail
gateway function such as SMTP and POP3 so that the E-mail communication is
available from the PC connected to LAN by using Inmarsat C.
Up to 32 k bite data is sent from the Inmarsat C.
Fig.1.3.3 LAN system
1.3.4 [DTE] port
The specification of the input/output signal is RS-232C. Data communication is
available by connecting PC. When installing another terminal unit(PC), it should be
connected to [DTE] port by using the straight cable.
Commercial printer for Windows and PP-510 can be connected to “Printer” port on PC.
Printer setting is made through “Printer setting” menu ([F1]-8).
With the commercial printer, error messages, such as “WARNING, TROUBLE: XXX”
are not printed out.
1.3.5 [D-GPS] port
The receiving signal, 1530 MHz to 1545 MHz is output at the level of 50Ω, -103 dBm
to -86 dBm.
