Metasys N2 (RS485) + 2 pulse inputs (VA, VB) (67-00-62) (PCB 5550-1110)
The N2 module is used for data transfer from MULTICAL® 62 heat and cooling meters to an N2 Master
in a Johnson Controls System. The N2 module transfers accumulated energy and volume, current
temperatures, flow and power from the heat or cooling meter to an N2 Master. N2 Open from
Johnson Controls is a widespread and established field bus protocol used within building automation.

SIOX module (Auto detect Baud rate) (602-00-64) (PCB 5920-193)
SIOX is used for data reading of small and medium size groups of heat meters via cable, the data
reading being presented by the main system, e.g. Mcom, Fix or Telefrang. Further information on
these systems can be ordered from the supplier in question. Furthermore, a configuration tool is
available from Telefrang.
The two-wire serial SIOX bus connection is opto-isolated from the meter and is connected without
regard to polarity (i.e. the polarity is unimportant). The module is powered by the SIOX bus.
Communication speed is between 300 and 19,200 baud. The module automatically uses the highest
possible communication speed. The module converts data from KMP protocol to SIOX-protocol.
