- PC control via serial ports RS232 or RS422;
d) Protections against:
•
Remote-unit relays under-voltage;
•
Remote-unit overheating;
•
Excessive antenna voltage;
•
Remote-unit relays "hot" switching;
•
Excessive RF power during tuning;
•
Atmospheric electricity via sphere spark gaps and a bleeder choke.
e) RCU for a distance up to 50m (164 feet) via optic link.
f) Resource-estimate function (STATUS) giving the percentage of inductors and capacitors involved to achieve a
match. This offers a possibility for monitoring the condition of the RF path, thus to forewarn possible problems.
g) Input SWR Check function.
h) Nonvolatile memory for 99 different user's tuning settings and selection of the power-on default.
6-3. STORAGE AND SHIPMENT
Should you need to transport the AATU, use the original packing as described
below.
First pull the mains plug out of the mains outlet, afterwards disconnect all cables from the rear panel of the RCU
(remove the ground connection last). Then remove the top cover of the RCU (use a Philips 2 screwdriver) and
disconnect the optic cable via loosening both optic-device knurled plastic nuts (of the split sockets) and the strain
relief on the rear panel.
Now uninstall the remote unit, observing the requirements of S.2-3 but in reverse order. At last, pack the RCU,
remote unit, installation accessories and cables in their original cartons and put the smaller cartons in the bigger one.
