SP tm 941 how to decrypt data. Heat calculator spt941 (mod,) instruction manual

To dispatch heat meters Logic SPT941, SPT943, you must first configure the communication parameters.

Press the MENU key and hold for about 2 seconds. The main menu of the heat meter will be displayed on the screen (using the example of SPT943.2), the cursor is placed under the GEN section:

Press the ↓ key to enter the General section of the menu, and then the -> key to move the cursor under the DB (database) section.

Press the ↓ key to enter the database, after which the screen will display the first of the section parameters and its value (EI=0):

Press the ↓ key several times until the NT option appears on the screen ( network address device).

If the facility uses one heat meter and it is not connected via a network with other Logic meters, we recommend setting the parameter value equal to one. (To change a parameter, press the ENTER key, then press the key to set the desired value, and press ENTER again to save.)

Now use the ↓ key to go to the next section parameter, CI (data interface configuration):

The value CI =0 is set by default and indicates connection communication equipment to the computer at a speed of 2400 bps. If you use a GSM modem to transfer data from the computer, we recommend setting this value and setting up the equipment and software on the dispatcher’s computer side accordingly. Firstly, it significantly saves the battery life of the computer. Secondly, in the case of unstable GSM communications, and the absence of external requests special form within 10 seconds, the computer will automatically set the parameter value equal to zero(2400 bps).

The setup of the heat meter is now complete (if you are using SPT941, the setup will be identical, with the only difference being that in the main menu of the device you first need to select the SETUP section, and then the DB section). Let's move on to connecting to the dispatch system. We recommend using (Fargo Maestro 100 or iRZ Q24) as a data transfer device.

A “smart” GSM modem does not require receiving staticIP addresses from the mobile operator, excludesfreezingGSM channel and module. Afterpower supplymodem automaticallywill come outto the network, will provide a transparent data transmission channel with a meter,and will becontrolconnection quality, rebooting if necessary.

Let's prepare a “smart” GSM modem for working with SPT941/943. Using, run the MtCfg utility from NPO Teplovizor and carry out necessary actions. After specifying all required parameters connection to the dispatch system, configure the modem port to connect to SPT941/943.

To do this, select the menu item Modem->UART Settings…

set the following values:


and press the button Save settings. Don't forget to check the box next to " Save settings in non-volatile memory«.

Now all devices are ready for operation, you need to perform physical connection. Unfasten the cover of the device to gain access to the terminals:



The RS-232 communication port we are interested in is located on connector X2:

Connect the MT9 modem and the heat meter in accordance with this diagram (the colors of the connecting lines in the diagram are arbitrary and do not match the colors of the conductors in the modem cable):

Sometimes it may be necessary to directly connect a laptop to a heat meter (service tasks, changing the device configuration, local data acquisition, etc. on-site work).
