hi, IN MY COMPANY BOUGHT AN ALLIGIANT VIEW SYSTEM SINCE SOME YEARS AGO, THE PROBLEM IS THAT THEY NEVER COULD CONECT IT, THE EQUIPMENT has two PORTS, the first is for the connection to the PC(RS232) AND PRINTER FOR THE SECOND , THE MANUAL SETUP SAYS THAT YOU GOT TO DO IT WHIT THE MASTER CONTROL SOFTWARE VIA PORT COM1 AND THE MASTER CONTROL SOFTWARE, WE PUT THE PARAMETERS LIKE CONM PORT, BAUD RATE, DATA BITS, STOP BITS AND PARITY, WE SELECT THE HANDSHAKING OPTION AND AUTO-BAND, we tried IN 3 PC'S BUT IS IMPOSSIBLE TO ACCESS, I GOT ALL THE CAMERAS AND MULTIPLEXER ALREADY CONECTED, AND NOTHING.. ANYONE KNOW WHAT CAN I DO? WHAT COULD BE THE PROBLEM, i KNOW THAT BOSCH BOUGHT THE LINE OF ALLEGIANT TO PHILIPS, MY NEW CAMERAS ARE BOSCH, BUT I CANT PROGRAM THE CENTRAL, WE ALSO CONECTED THE KEYBOARD VIA RJ11, IT TURN ON BUT I CAN NOT MOVE THE CAMERAS, PLEASE HELP ME
