Rs232 - For Use Without Brookfield Software (For Customers Using Their Own Software) - Ametek BrookField TC Series Operator's Manual

RS232 — For use without Brookfield Software (for customers using their own software)
Serial Connector — A 9-pin D connector is provided on the back of the Temperature Controller for RS232
data communication. A serial cable that uses only the following pins should be used to connect the
Temperature Controller to the computer:
Pin #2 — Data read (data from computer)
Pin #3 — Data transmit (data to computer)
Pin #5 — Signal ground
IMPORTANT: Do not use a serial cable that connects to the unused pins on the Temperature
Controller's RS232 connection.
RS232 Protocol — The Temperature Controller uses the following RS232 protocol:
Data bits — 8
Parity — None
Stop bits — 1
Flow control — None
Baud rate — Selectable (Temperature Controller/PC baud rates must match; 57600 is
recommended).
Communication Commands — Commands must be entered in the exact format shown. Do not send a LF
(line feed) after the [CR] (carriage return). Be sure to follow character case exactly.
A response must be received from the Temperature Controller before another command can be sent. All
responses are terminated with a single [CR], ASCII value = 13.
COMMAND
Read current fluid temperature
Read current set point
Change set point *
Read remaining ramp time
Set ramp time *
Identifies controller
Illegal command
Set RUN mode **
Set STANDBY mode **
*. To change set point or set ramp time, enter the command, wait for the response, and then enter RA1{CR}.
**. The Temperature Controller may be forced into only two states using the RA command: RA1{CR} (Run) and
RA2{CR} (Standby).
