This page displays various HPA settings:
•
Prtcl. - current HPA remote control protocol. The value can be set to
"Terminal", if terminal mode protocol is currently active and "Normal" for
string I/O type protocol.
•
Baud - selected baud rate for remote control serial port. Selection: "2400",
"4800", "9600", "19200", "38400";
•
Intrfc. - selected serial port interface. Selection: "RS232", "RS485".
•
Addrs. - HPA remote control network address. Value could be in range from
0 to 254. Note: address 255 is reserved for global calls and shouldn't be
used for an individual unit’s addressing.
•
Buzzer - Audible alarm availability. "Dis" for disabled or "Enb" for enabled.
•
Latch - Fault latch option selection. "Dis" for disabled or "Enb" for enabled.
2.2.1.5 Sys Info Page 5
Page 5 shows settings related to the HPA 1:1 Redundant System operation.
•
Mode - indicates HPA operational mode. Value can be set to "1:1" for 1:1
redundancy mode and "Stdaln" for stand alone mode;
•
Stby. - shows HPA standby state selection. "Hot" for hot standby operation
(HPA retains unmuted state during standby period) and "Cold" for cold
standby (HPA always mutes itself in standby mode and unmutes when
switched back on-line).
•
Ctrl. - shows HPA control style. "Local" - both local and remote control are
supported and "Remote" when only remote control provided (keypad
locked);
•
Switch - indicates switching style. "Auto" for automatic fault tracking/
switching and "Manual" if redundancy switching is provided by the operator.
•
Unit - redundancy topological factor. "HPA1" for HPA connected to the RF
switch port 1 or 4 (Online Position 1 of the RF switch). "HPA2" for HPA
connected to the RF switch port 2 or 3 (Online Position2 of the RF switch).
2.2.1.6 Sys Info Page 6
This page shows the status of the HPA’s internal power supplies
•
PS1(V) - main power supply 1 output voltage with resolution of 0.1V. Normal
output voltage should be in range of 11 to 13 V.
•
PS2(V) - main power supply 2 output voltage.
•
Boost1(V) - booster power supply 1 output voltage with resolution of 0.1V.
Normal range 24 to 30 V (typical 28V);
•
Boost2(V) - booster power supply 2 output voltage.
•
DC (A) - total DC current draw by RF modules from main power supply.
Value varies depending on the power level of the HPA. If the HPA is muted,
current normally drops to within the 0 to 5 A range.
