8. REF If this LED is green, the forward reflected RF power is within
acceptable levels. If this LED is red, the reflected power from the
antenna system is too high, and must be rectified.
9. LOCAL If this LED is green, the system is operating normally and can
be accessed remotely, via TCP/IP ethernet. If it is red, the systems
settings are being accessed locally (via the front panel display menu),
which takes precedence.
10. RF OUTPUT ‘N’-type socket. This is the RF power output for the
antenna system. Connect the mask filter and antenna to this socket.
11. ETHERNET RJ45 ICP/IP Socket. If internet connectivity is required,
connect the LAN to this socket. Ensure that the local router has
maximum security and Firewall protection enabled.
12. EARTH STUD M4 threaded earth stud. Connect additional earthing
to this point, in accordance with local regulations.
13. REMOTE . This 9-way ‘D-sub’ socket can be used for remote control
and monitoring of the transmitter. It also enables automatic switching
of N+1 back-up system configurations.
Pin 1. This output pulls-low when the RF forward power
condition is OK. It will float high when an ‘alarm’ condition (no RF
output) is present.
Pin 2. This output pulls-low when the RF reflected power
condition is OK. It will float high when an ‘alarm’ condition
(reflected power too high) is present.
The above ‘Open Collector’ outputs are capable of operation up
to 50V and sinking a current of 75mA maximum. The normally
high, (ie. ‘pull low’ upon alarm condition) provides inherent
‘power failure’ or ‘cable connection failure’ signalling.
Pin 3. Grounding this pin will mute the RF output of the
transmitter.
14. EDI1 IN. RJ45 ICP/IP Socket. Connect the main EDI feed from the
multiplexer to this input.
15. EDI2 IN. RJ45 ICP/IP Socket. Connect the reserve or secondary EDI
feed from the multiplexer to this input.
