6300 Rev H User's Manual
The model 6300 is capable of communicating with a PC via the RS232 serial interface. Using this interface it is
possible to perform all the functions that can be performed using the Remote unit. Therefore, operation of
the 6300 can be fully automated.
Profiles can be loaded through the RS232 interface. For more details on Profiles, please refer to Section 4.
The RS232 serial interface is a three-wire interface using the signals RX, TX and GND. Each byte of data is
sent or received in ASCII format using 8 bits per byte, with 1 stop bit, no parity at 9600 baud.
The pin-out of the interface is as follows:
Pin 2 - Transmit (TX)
Pin 3 - Receive (RX)
Pin 5 - Signal ground (GND)
The baud rate, parity, bits per byte, and number of stop bits cannot be altered and is set to 9600, No parity, 8
bits and 1 stop bit respectively (9600, N, 8, 1).

COMMUNICATION SETUP

On the PC, the COM1 serial port (or any other COM port) or a USB port (configured as a COM port) can be
used to communicate with the 6300. If a USB port is used, it is necessary to use an in-line USB to RS232
converter. This converter is provided with the 6300. A RS232 cable (DB9-male to DB9-female) is also
provided with the 6300.
Connect the COM port on the PC to the RS232 port on the 6300, using the cable (and USB to RS232 converter)
provided. The RS232 connector is located on the top panel, under a protective cover. Run a serial
communication program similar to Hyperterminal on the PC. Configure the COM port being used on the PC
to operate at 9600,N,8,1. Setup Hyperterminal to echo typed characters so you can see what you are entering
on the PC.
To verify communication, make sure the 6300 is operational, then in Hyperterminal, enter the command 'PA'
followed by the ENTER key.
communication between the PC and 6300 is functional.
