Remote I/O Connector Pinout Table
Pin # Function
1 PA#8 Current Monitor (a buffered metering output with 1 V = 2 A)
2 PA#7 Current Monitor (a buffered metering output with 1 V = 2 A)
3 Ground
4 Remote RAISE Power (a momentary switch, on this pin, when held low will
raise the power level 10 watts every 0.5 seconds)
5 Remote RF Power Control (a resistor to ground on this pin reduces RF
power output level below internal limits. See Section 2.6, page 2–7)
6 Ground
7 Remote AC Power On (a latching switch, on this pin, when held low will turn
the AC power supply on)
8 Fault Summary (the voltage from this pin goes to +5 V if any fault occurs and
drops below 2V when the fault goes away)
9 Ground
10 ALC (the voltage from this pin is a direct reading of automatic level control
voltage, not buffered)
11 PA Temperature (a buffered metering output with 1 V = 20° C)
12 SWR (a buffered metering output with a calculated reading of standing wave
ratio in VDC)
13 RF Output Power (a buffered metering output with a calculated reading of
output power of 1 V = 1000 W)
14 Input Power Reference (a buffered metering output with a DC voltage
representing input power)
15 Remote LOWER Power (a momentary switch, on this pin, when held low will
lower the power level 10 watts every 0.5 seconds)
16 PA#6 Current Monitor (a buffered metering output with 1 V = 2 A)
17 PA#5 Current Monitor (a buffered metering output with 1 V = 2 A)
18 Ground
19 PA#4 Current Monitor (a buffered metering output with 1 V = 2 A)
20 PA#3 Current Monitor (a buffered metering output with 1 V = 2 A)
21 Ground
22 PA#2 Current Monitor (a buffered metering output with 1 V = 2 A)
23 PA#1 Current Monitor (a buffered metering output with 1 V = 2 A)
24 PA Total Current Monitor (a buffered metering output with 1 V = 20 A)
25 PA Volts (a buffered metering output with 1 V = 10 V)
Note: PA = Power Amplifier
