FTK-CC temperature control device for use of cylinder measuring system in the temperature range -10☌.+90☌ (liquid’s temperature control).In this chapter you get information concerning mounting and attachment of the following accessories components: III.3 Mounting of temperature controlled measuring devices Please read information concerning installation of the computer system in this Operation Manual. Use data link cable of BROOKFIELD delivery only! Turn on the R/S Rheometer and your computer system again.
#WHAT IS THE PURPOSE LOOPBACK CABLE OR PLUG SERIAL#
Connect the other end of the data link with a free serial interface RS-232 (f.e. Insert the data link into the plug “RS232” at the back side of the rheometer.
#WHAT IS THE PURPOSE LOOPBACK CABLE OR PLUG PC#
If the R/S Rheometer has to be used in “REMOTE” mode with PC support (Rheo-program package) or with serial data-terminal for data logging it is necessary to connect the data link with the plug “RS232” at the instrument back side. To print data-values from R/S Rheometer all printers can be used which are printing text in ASCII-mode. This cable is supplied with the printer in most cases. Standard printer cable (Printer ↔ PC) can be used as printer connecting cable. Insert the printer connecting cable into the connector “CENTRONICS” at the back side of rheometer.

Turn off the R/S Rheometer with the mains switch “POWER” at the back side. You should use obligatory a printer with parallel “CENTRONICS” interface. You must preset “Printer” as output device to print the measuring values during measurement (see Chapter 6). Printer can be connected directly to the interface connector of the R/S Rheometer when measuring without PC support. The AC-adaptor should not remain connected to the mains socket during long time with disconnected plug of the DC cable from the connector “DC” at the back side.īefore disconnecting R/S Rheometer from mains supply be sure that the Rheometer is switched off. insert the mains plug of the mains cable into a grounded socket insert the plug of DC cable into the connector “DC” at the back side of R/S Rheometer insert the instrument connector of the mains cable into AC adaptor be sure that R/S Rheometer is switched off (mains switch “POWER” at the back side of the instrument) Pay attention also to “Requirements to the mains cable” (see Appendix). Connect the AC adaptor only using the plug in a proper way grounded to avoid electric shocks or damage of the system components. The AC-adaptor may be inserted to the socket with corresponding grounding only. Only the AC-adaptor delivered by BROOKFIELD with your Rheometer may be used for power supply of R/S Rheometer. Mobile Communications basics 2G GSM 3G UMTS 4G LTE 5G WiFi IEEE 802.15.The AC adaptor supplies R/S Rheometer with power. It is often convenient to be able to have a connector wired up for this purpose if fault-finding and service are to be undertaken with equipment using RS232. The loopback connections are useful on occasions for applications like self test.

The connections for the serial loopback connector are given below in tabular form for a DB-9 D-type connector using the common pinout connections.ĭB9 Connector Serial Loopback ConnectionsĪ table showing the loopback connections when using a DB25 D-type connector using the common pinouts is shown below.ĭB25 Connector Serial Loopback Connections Although it may not be necessary to incorporate all the handshaking connections for all applications, they have nevertheless been incorporated so that the serial loopback connector should work for all situations. The connections given below form a commonly used configuration. There is more than one way to wire up a serial loopback connector. The loopback plug connects serial inputs to serial outputs so that the port may be tested. They can be made very easily either for DB9 or DB25 way connectors. RS232 loopback connectors are very easy to make up. However it will be able to test the basic functionality and provide a good level of confidence about the ability of the equipment to send and receive and generally check the operation of the serial port. The test loopback connector approach to testing has its limitations as it will not be able to detect speed mismatches or the like as the same issue is likely to be present on transmit and receive. In this way the equipment can be used on its own to check that it can communicate, even if it is only with itself. When testing RS232 links, it is often useful to have a test loopback connector.
