|2||AHC_PWR_EN||IN||Connect to DGND to turn off the antenna head, leave floating (or pull to 12V) to turn on antenna head|

|9||EXT_TX_232||IN||RS232 Levels, Switch antenna between TX and RX, also requires commands via the CMD interface|
To turn the antenna on/off using a Raspberry Pi or other microcontroller, the AHC_PWR_EN pin must be connected to ground through an NPN transistor as follows:
In addition, the "array enable" command must be sent after power on otherwise no further communication can take place. Note that after power on, the serial buffer may contain garbage bytes which may prefix the response of the "array enable" command.
Serial port config: 115200bps baudrate, 8 bit data, no parity, 1 stop bit, no flow control
The commands work the same way over either the RS232 or the RS485 (originally via a USB adapter board) connections.
