RS-232 Configuration

Before you can operate the LDT-5900 Series Temperature Controller over RS-
232, you need to select the baud rate. The instrument's baud rate setting must
match the baud rate used by the host controller serial RS-232 interface, which is
typically a serial COMM port on your PC. The following sections describe reading
and changing the baud rate.
The LDT-5900 Series Temperature Controller's RS-232 is configured for 8-bit, no
parity, no flow control, and one stop bit. This is not adjustable. Only the baud rate
may be altered.

Reading the Baud Rate

Press the MAIN/LOCAL key in the system section of the front panel to view the
"System Menu". Page 1 of the System Menu is the Communications Menu.
Press the down arrow key and the RS-232 baud rate will be displayed.

Changing the Baud Rate

The factory default baud rate is 9600. The allowable baud rates are 1200, 2400,
4800, 9600, 19200, 38400, 57600, 115200, and 230400. Refer to the serial port
configuration of your PC (if used) for the allowable baud rates. If it is necessary to
change the baud rate, press the MAIN/LOCAL key in the System section of the
front panel. Page 1 displays the Communications menu. Press the down arrow to
select the RS-232 Baud field. The baud rate can be changed by turning the adjust
knob until the desired baud rate is displayed and then press the "ENTER/LOCK"
key. The baud rate will then be stored in non-volatile memory.
