8. REF I this LED is green, the orward re lected RF power is within
acceptable levels. I this LED is red, the re lected power rom the
antenna system is too high, and must be recti ied.
9. LOCAL I this LED is green, the system is operating normally and can
be accessed remotely, via TCP/IP ethernet. I it is red, the systems
settings are being accessed locally (via the ront panel display menu),
which takes precedence.
10. RF OUTPUT ‘N’-type socket. This is the RF power output or the
antenna system. Connect the mask ilter and antenna to this socket.
11. ETHERNET RJ45 ICP/IP Socket. I 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 or remote control
and monitoring o the transmitter. It also enables automatic switching
o N+1 back-up system con igurations.
Pin 1. This output pulls-low when the RF orward power
condition is OK. It will loat high when an ‘alarm’ condition (no RF
output) is present.
Pin 2. This output pulls-low when the RF re lected power
condition is OK. It will loat high when an ‘alarm’ condition
(re lected power too high) is present.
The above ‘Open Collector’ outputs are capable o operation up
to 50V and sinking a current o 75mA maximum. The normally
high, (ie. ‘pull low’ upon alarm condition) provides inherent
‘power ailure’ or ‘cable connection ailure’ signalling.
Pin 3. Grounding this pin will mute the RF output o the
transmitter.
14. EDI1 IN. RJ45 ICP/IP Socket. Connect the main EDI eed rom the
multiplexer to this input.
15. EDI2 IN. RJ45 ICP/IP Socket. Connect the reserve or secondary EDI
eed rom the multiplexer to this input.
