COMMUNICATIONS

The TE-3000 is equipped with a full-duplex RS-232C point-to-point
interface as well as a half-duplex RS-485 network interface. Commands
and Queries may be sent to the TE-3000 via either interface and Re-
sponses and Reports received by a master controlling computer. This
interface is configured as 8 data bits with no parity and one stop bit. The
Baud rate of the interface is configured only via the front panel menu
system and can be set at 1200, 2400, 9600, 19.2k, or 38.4k Baud. The
mode of operation, point-to-point or polled (multi-drop), can only be
configured via the front panel menu system. Time interval reports of the
actual and desired bath temperature can only be enabled if the TE-3000 is
configured in the point-to-point mode of operation.

A. Downloading firmware updates

The TE-3000 is capable of receiving new operational software via either
the RS-232 or RS-485 interface. If this software is updated and a new
release is issued by

CANNON

®

Instrument Company, a diskette will be

sent to the users along with instructions on how to perform this upgrade.

Download button

A “download” push-button is provided on the rear panel of the TE-3000
which places the instrument into the download mode. When this mode is
entered, the front panel display will show the version number of both the
resident download hardware code and the version of the present opera-
tional firmware. A computer will then be required to send the new
firmware to the TE-3000.

B. Full duplex (POINT-TO-POINT) operations

The RS-232 interface is furnished for a direct connection from one TE-
3000 to one computer. A DB-25 connector, configured as Data Commu-
nication Equipment (DCE), is provided on the rear panel of the TE-3000.
This configuration permits a direct connection (straight through cable -
pins 1 through 8, & 20) from the TE-3000 to virtually any computer.
Most present day computers have a DB-9 connector which requires the
use of an adaptor or a cable with a DB-25 male connector on one end and
a DB-9 female connector on the other end. For a complete description of
the Commands, Queries, Responses and Reports on this interface, please
refer to the section D which follows.
