Chapter 4 – Temperature Controller
TestEquity 1007C Temperature Chamber Page 4-15
Factory Page
The Factory Page provides access to menus for controller diagnostics and calibration. TestEquity
has configured the security to require a password for access to the Setup Page. However, there
will be times when entry into these menus is necessary. For example, you may need to gain
access to Factory Page in order to perform a calibration, or to change the security password. You
must call TestEquity at 877-512-3457 or 805-480-0638 to obtain the password.
! CAUTION: NEVER select “Full Defaults” in the Factory/Test Menu. This will erase all
the correct values which are documented in the “Series F4 Temperature
Controller Setup Parameters” section of this manual.
Computer Interface
! CAUTION: Every setting in the F4 Controller can be accessed via the computer interface.
Improper modifications to configuration settings can result in erratic
performance and unreliable operation. Setup examples in the “Series F4
User’s Manual” are NOT applicable to this chamber. The correct values are
documented in the “Series F4 Temperature Controller Setup Parameters”
section of this manual.
RS-232C
The F4 Temperature Controller has an RS-232C interface. A DB-9 connector is located on the
rear panel. It is wired to accommodate a null-modem cable. To communicate with the controller
from a PC, you need to run software that uses the Modbus RTU protocol. Each controller
function has a “register” number which can be read or written to (when applicable). These
registers are listed Chapter Seven of the “Series F4 User’s Manual”. RS-232C Modbus
programming resources can be downloaded from http://www.testequity.com/RS232.
Common Modbus Registers
• The actual chamber temperature reading is Modbus register 100 (Input 1 Value).
• The static temperature set point is Modbus register 300 (Set Point 1).
• The temperature set point during a profile is Modbus register 4122 (Set Point 1, Current
Profile Status).
• The decimal points are implied. For example, 1005 is actually 100.5 and -230 is -23.0.
GPIB (optional)
The optional GPIB interface, model TE-1052 consists of an external converter box that connects
to the chamber’s RS-232C interface. Model TE-0003 is internal to the chamber. GPIB
programming resources and LabVIEW drivers can be downloaded from
http://www.testequity.com/GPIB.
Ethernet (optional)
The optional Ethernet interface, model TE-1055, consists of an external converter box that
connects to the chamber’s RS-232C interface. Ethernet programming resources can be
downloaded from http://www.testequity.com/ETHERNET.
