Soyuz GSM PCB / ТР-100 GSM IV: four discrete inputs
The information below is valid for the “Soyuz GSM PCB” version 10.19 firmware and the Hubble configurator version 6.3.
If the Soyuz GSM PCB has been updated to version 10.19, then when connected to the device using the Hubble configurator or the engineer panel in the Cloud, the Zones tab will display four zones instead of two:
At the same time, it is impossible to enable or change the settings for zones with numbers 3 and 4. In order for zones to become available, you need to enable them on the “Devices” tab.
Zone number 3
Additional zone number 3 is organized instead of the serial port.
Both cables of this zone should be connected to the “RS-TTL” terminals, while the jumper of the operating mode of the serial port should be set to the lower position (TTL):
In order to switch the device to use the serial port in the third zone mode, it is necessary in the configurator to check the “Use RS-TTL terminals as zone number 3” box, in the “Devices” tab, in the “Serial port” section:
Zone number 4
Additional zone number 4 is organized instead of the serial port.
Both cables of this zone must be connected to the “TEL IN” terminals:
In order to switch the device to use the telephone input in the fourth zone mode, it is necessary in the configurator ещ check the “Use TEL IN terminals as zone number 4” box, in the “Devices” tab, in the “Telephone line” section:
After the additional zones are activated, they can be configured in the same way as the regular zones of the device:
Additional zones can be included both, and separately, that is, you can include only the third or only the fourth zone.
Regular zones of the device PCB GSM Soyuz are connected to the “ZONE” terminals, while the “GND” terminal for connecting the signal cables of these zones is common.
Unlike standard ones, additional zones must be connected without using a common terminal: both cables must be connected either to the “RS-TTL” terminals (for zone number 3) or to the “TEL IN” terminals (for zone number 4).
It should be noted that the entrances that are used as additional zones were not designed as such, therefore, when connecting conductors to them, the following should be kept in mind:
- total cable resistance should not exceed 300 Ohms;
- for zone 3, the potential of the connected conductors with respect to the earth should not exceed 6 V;
- for zone 4, the potential of the connected conductors with respect to the earth should not exceed 12 V;
If we reformulate what was written in the previous paragraph, then we can say that these zones can be connected to the dry contacts of another device without the slightest fear. In this case, you can use wires that are several tens of meters long.
