Communicational board INMOD 1
  • Purpose: The communicational board INMOD 1 is designed to transmit commands for switching on and switching off of sites under protection that are connected through a local security central to a central station INMOD 064.
  • How it works: Information is sent through modulation of the value of the balance resistance of the site through a parallel connecting of an additional resistor. In this way current does not change and the influence of the transitional processes over the line is decreased. The speed of transmission is about 10 bps. Except information switch on/ switch off, it is also transmitted 8-bit identification code of the board, different for each site.
  • Connecting of the Communicational Board INMOD 1:
    • JP1 - 1+12V
    • JP1 - 2GND
    • JP2 - 1 Entry for signal on/off; open circuit - disarmed site, closed circuit - armed site
    • JP2 - 2GND
    • JP3 - 1,2 Connected in parallel of the balance resistance of the site

Communicational Board INMOD 2
  • Purpose: The communicational board INMOD 2 is designed to transmit commands for switching on and switching off of sites under protection, information for the state of the battery, alternating-current supply voltage 220V and the status of 3 zones of sites that are connected through a local security system (or without it) to a central station INMOD 064.
  • How it works: Information is sent through modulation of the value of the balance resistance of the site through a parallel connecting of an additional resistor. In this way current does not change and the influence of the transitional processes over the line is decreased. The speed of transmission is about 10 bps . Except information switch on/ switch off, battery, 220V, status of the 3 zones, it is also transmitted 8-bit identification code of the board, different for each site.
  • Connecting of the Communicational Board INMOD 2:
    • JP1 - 1GND
    • JP1 - 2+12V
    • JP2 - 1AC connected to the one alternating-current arm of the detecting axle
    • JP2 - 2BAT + battery 12V
    • JP3 - 1Z3 zone 3
    • JP3 - 2Z2 zone 2
    • JP4 - 1Z1 zone 1
    • JP4 - 2ON entry for signal on/off; open circuit - disarmed site, closed circuit - armed site
    • JP5 - 1Connecting of a LED to ground, which shows the status of the site (light on - switch on)
    • JP5 - 2GND
    • JP2 - 1,2Connected in parallel of the balance resistance of the site

Fixing of the jumpers
  • By J2 and J3 it is set the delay time for zones Z1 and Z2 at leaving the site – 0, 10, 20, 30 seconds.
  • By J1 it is set the delay time for zone Z1 at entering the site, which is equal to one half of the time set by the jumpers J2 and J3 or is equal to 0.
  • The zone Z3 is 24-hour (a tamper or a panic-button).
