Accessories
Honeywell Meter Point Connect devices provide RS485 signal
interface for bus connection(s), and require use of level
converter device(s) for conversion of RS485 levels to M-Bus
voltage levels for connection to meters. Following level
converters have been tested for use with MPC devices:
RS485 to M-Bus Converters:
Relay Model PW60: RS485 > M-Bus level converter for up to
60 devices.
ADFweb Model HD67022M-20: RS485 > M-Bus level
converter for up to 20 devices.
RS232 TO M-BUS CONVERTERS:
(These are used with RS485 > RS232 converters listed
below)
Relay Model PW3: RS232 > M-Bus level converter for up to 3
devices
Relay Model PW20: RS232 > M-Bus level converter for up to
20 devices
RS485 TO RS232 CONVERTERS:
MOXA Model TCC-108I: RS485 > RS232 converter.
B&B Model 4WSD90TB: RS485 > RS232 converter.
ICS Model I-7520R: RS485 > RS232 converter.
Connecting multiple M-Bus level Converters on MPC
single M-Bus Channel:
Fig. 2. Connecting multiple M-Bus Converters
In order to connect more meters to an M-Bus port than
supported by a single converter device, additional M-Bus
converter(s) can be connected to the RS485 M-Bus on M1 or
M2 devices in parallel with the existing converter. Only the
converters that directly convert between RS-485 and M-Bus
(and do not use an intermediate RS232 type connection) can
be connected in this manner. The end-of-line (EOL)
terminations and biasing for each device connected to the
RS485 M-Bus (CH1 or CH2) as well as the port switch
settings for MPC should be set in accordance with location of
each device on the bus.
