4.4.7 Set Communications?
Baud Rate: The display contains a bi-directional, industry-standard RS-232C serial port that enables users to operate
the instrument remotely with a keypad or computer that supports the RS-232C protocol. All keypad operations, and
most display operations, can be performed remotely through this port. (See page 20 for operation instructions.)
The display supports the communication rates of 9600, 4800, 2400, 1200 and 300 baud. The default setting is 9600
baud. Other parameters are fixed at 8 bits, 1 stop bit, no parity.
Note:
The 300-baud setting is provided for compatibility with older equipment; however, the use of 300 baud
greatly limits the computation speed of the TMO2D, and its use is not recommended.
The Set Communications? submenu enables you to select both the baud rate and the update rate, when they
communicate with the TMO2D through the RS-232 port.
Note:
The baud rate can be changed using a terminal connected to the RS-232C port. However, this is not
recommended, as the TMO2D will immediately change to the new baud rate. Display and keyboard
operation will not be correct until the baud rate of the terminal is changed to match the new baud rate set in
the TMO2D.
Update Rate: This option is used to change the interval at which data goes to the serial port. The current data interval
will appear in brackets, and users can enter a new data interval.
