Ameritron RCS-10

MADE IN U.S.A.

The RCS-10 is internally fused with a standard auto-glass (3AG) style 1-ampere fuse. If

your power supply is capable of supplying significantly more than one ampere, you

should also fuse the power lead at the power supply with a low-current fuse. Installing a

fuse at the power supply eliminates safety hazards associated with overheated power

leads, if the leads should become shorted.

Terminals A, B, and C are BCD encoded outputs for the relay unit. Terminal "A" is BCD

1, terminal "B" BCD 2, and terminal "C" is BCD 4. This provides a numerical total of

zero through seven for selecting relays. Antenna port one on the relay box is selected with

all BCD outputs zero, port 2 with only BCD "A" high, and so on until port eight is

selected with all BCD ports high.

When antenna position one is selected, voltage on A, B and C is zero volts. This is the

same voltage as when the control head power is turned off. Because of that, antenna port

1 is selected whenever the switch is off or has no power.

There is an internal 2-pin jumper on the left side (rear view) of the front-panel printed

circuit board. When these pins are NOT jumpered, the LED's are dim. When these pins

are jumped, the LED's are brighter. When using voltages over 20 volts, you must be sure

these pins are not jumped.
