MULTICAL® 602
100 Kamstrup A/S ∙ Technical Description ∙ 5512 ‐ 931_N1_GB_11.2016
10.2.16 Metasys N2 (RS485) + 2 pulse inputs (VA, VB) (67-00-62) (PCB 5550-1110)
The N2 module is used for data transfer from MULTICAL

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. The N2 module for MULTICAL

ensures simple integration from
Kamstrup’s heat and cooling meters to N2 Open based systems. Adress area is 1-255 determined by the last three
digits of the meters customer number.
Further details about the Metasys N2 module appear from data sheet 5810-925, GB-version.
10.2.17 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 optoisolated 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 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.
10.2.18 BACnet MS/TP (B-ASC) RS485 + 2 pulse inputs (VA, VB) (67-00-66) (PCB 5550-1240)
The BACnet module is used for data transfer from MULTICAL heat cooling and water meters into BACnet systems.
The BACnet module transfers Meter number (programmable), Serial number, Accumulated heat energy (E1),
Accumulated cooling energy (E3), Accumulated volume flow (V1), Inlet temperature, Outlet temperature,
Temperature difference, Actual flow, Actual power, Accumulated values from additional meters via puls InA, InB,
Info codes from the heat, cooling and water meter to the BACnet system. BACnet is a widespread and established
field bus protocol used within building automation. The BACnet module for MULTICAL
ensures simple integration
from Kamstrup’s heat, cooling and water meters to BACnet based systems. The Module can be used as both master
or slave, depending on the used MAC address.
Further details about the BACnet MS/TP module appear from data sheet 5810-1055, GB-version.
