How do I send hex command as mmcorej.CharVector to serial port?

Hi All,
I am trying to send a hex message to a light source connected by a usb through the virtual serial port. The source expects an up to 8 byte message, for example 'A9035301A95C' in order to change state. I am trying to communicate with it via Micro Manager adapter for Free Serial Port. Micro Manager command has the following format: setSerialPortCommand(String portLabel, String command, String term) where String command is java.lang.String command.
I tried various forms of the code below, but with no success. I would greatly appreciate any advice on the correct format for the command.
cheers, Maria
function [] = setBrightFieldManual(color,intensity)
global mmc;
comPortScopeLED = 'COM5';
presetColors = {'3000K','4500K','6500K','Red ','Green','Blue '}; % from manual
colorNumbers = {'01','02','03','04','05','06'};
colorMap = containers.Map(presetColors,colorNumbers);
intensityHEX = dec2hex(intensity);
checkSum = dec2hex(2^8-(81+hex2dec(colorMap(color))+intensity));
playPresetColorString = {'A9','04','4D',colorMap(color),intensityHEX,checkSum,'5C'};
setManualControllerLockoutON = {'A9','03','53','01','A9','5C'};
setUSBControl = {'A9','03','27','03','D3','5C'};
setManualControllerLockoutOFF = {'A9','03','53','00','AA','5C'};
getManualControllerLockout = {'A9','02','54','AA','5C'};
setAllShuttersOpen = {'A9','03','55','07','A1','5C'};
mmc.setSerialPortCommand(comPortScopeLED,'A9035301A95C',''); % also tried (comPortScopeLED,'setManualControllerLockoutON','')
mmc.setSerialPortCommand(comPortScopeLED,'A90254AA5C','');
answer=char(mmc.readFromSerialPort(comPortScopeLED));
disp(answer);
mmc.setSerialPortCommand(comPortScopeLED,'setUSBControl','');
mmc.setSerialPortCommand(comPortScopeLED,'setAllShuttersOpen','');
mmc.setSerialPortCommand(comPortScopeLED,'setManualControllerLockoutOFF','');

h2js = @(hexstring) java.lang.string( char(sscanf(hexstring, '%02x')) )
mmc.setSerialPortCommand(comPortScopeLED, h2js('A9035301A95C'), '');
That is, you need to convert the hex to bytes, and the bytes to java string.
