Page 3: Introduction
Versatile: The RCS-12 will work with the 5 and 8 position tower-mounted relay boxes from Ameritron. However, the RCS-12 will work with any relays using up to 30VDC. Output formats can be 1 of 8, 3 line BCD, or 4 line BCD. -
Page 4: Overview
The RCS-12 will operate with simple push-button operation in Manual mode. In Automatic mode, the RCS-12 reads Band Output Data from the appropriate jack on the back of your transceiver(s). The RCS- 12 is designed to work with most Icom, Yaesu, and Kenwood transceivers. There are separate inputs for each of these input types. -

RCS-12. This cable should be fitted with an 8-pin DIN plug on the RCS-12 side and end-stripped on the relay box end so that it may be attached to the terminal strip on the RCS-10 (see the diagrams below and the RCS-10 manual). -
Page 7: Using Direct Or Regulated Relay Voltage
The RCS-12 provides two types of voltages for controlling the relays: Direct or Regulated. The default setting is Direct and uses the power supplied to the RCS-12 to drive the switching relays. The Regulated setting drives the relays using a 12V regulated supply. Selecting the correct modes is accomplished setting JMP 4 located towards the front of the RCS-12. -

The diagram below shows how to connect a Kenwood radio with a DB-9 Com port to the RCS-12. Note that pin 7 and 8 (RTS, CTS) on the Kenwood port are connected together. This ensures that the Kenwood will send the status information to the RCS-12. -

Ameritron RCS-12 Instruction Manual Automatic Antenna Switch Auxiliary Input The Auxiliary Input Port allows remote control of the antenna buttons on the antenna switch. The port is a female DB-9 connection with the pin-out shown below. Applying a ground to any of the Aux pins will select the appropriate antenna. -
Page 11: Radio Key In
*Ground is on the shell of the DB-9 plug Radio Key In The Radio Key In jack, when pulled to ground, will prevent the RCS-12 from switching antennas. The Radio Key In jack is +5V open collector and will deliver 1mA when pulled to ground. This jack should be connected to the transceiver’s relay control line that goes to ground on transmit. -
Page 12: Operation
Do not attempt to use this function unless the Amplifier Key Line is connected to the Radio Key In on the rear panel of the RCS-12, or else you will invoke severe damage to your station equipment due to “hot switching.” Make sure the TRANSMIT LED on the front panel of the RCS-12 is always illuminated when transmitting. -
Page 13: Setting Relay Switching Delay
Setting Relay Switching Delay With the power switch off, hold the ANT 1 button while switching the RCS-12 power on. This allows the setting of the relay switching delay. The delay is selected by pressing one of the eight antenna selection buttons. -
