The Procon BAC-IP/50 unit allows a BACnet/IP building
management system (BMS) to monitor and control air-conditioning
units attached to a Mitsubishi G-50A, GB-50A or AG-150 central
controller.
Depending on the air-conditioning configuration within the G-50,
up to 50 groups can be monitored / controlled. The error state of up
to 50 OC/BC units can also be monitored.

2.1 Ethernet
The Procon BAC-IP/50 is a 10Base-T half duplex device and
needs to be connected to the G-50 and the BACnet/IP network.
Fig.1 shows the use of a hub / switch ( not supplied ) to make the
connections, but the Procon unit and the G-50 could just as easily
be connected directly to the BACnet/IP network.

Connection Details
Fig.2 Connection Details
All electrical work should be carried out by a competent person
and wiring must be in accordance with the national electrical
installation regulations.
Note:a) The Procon BAC-IP/50 and the G-50 require separate
IP addresses which must be on the same subnet.
b) The BAC-IP/50 does not support Auto-Negotiation.

2.2 Configuration Port
This connector is only to be used for unit configuration (via RS485
or RS232) and updating the firmware (via RS232 only).
2.3 Enable Link
Allows a normally-closed volt-free contact to set or reset the
‘Forced- Off’ feature in the G-50. While the ‘Forced-Off’ feature is
enabled, all air-conditioning units are switched off and all remote-
controllers are disabled.
Upon detection of the open contact, the Procon unit sends the
‘Forced-Off’ Set command to the G-50, and resends at 5 seconds
intervals while the contact is open.
As soon as the contact closes, the Procon unit sends the ‘Forced-
Off’ Reset command to the G-50 once only. This ensures that any
subsequent ‘Forced-Off’ commands sent via the BACnet BMS
system are not overridden.

2.4 Power Supply
The Procon BAC-IP/50 will accept either 12v or 24v AC and has a
consumption of 8VA. The unit is shipped setup for 24v AC. The
internal fuse is rated T500mA.

3. Air-Conditioning Group Configuration
The groupings set up in the G-50 determine which unit
addresses can accept commands from the BACnet BMS system.
The group number is defined as ‘the lowest indoor unit address
within the group’. This then becomes the ‘master’ address for the
group, and is the only address within that group than can accept
commands.
The other units within a group can be classed as ‘slave’ units
and contain the same status parameter values as the ‘master’,
apart from the Error Code, which is unique to each unit.
In the example above, addresses 01, 03, 06 and 08 are the
‘master’ units, and 02, 04, 05 and 07 are the ‘slave’ units.

5. Special Functions
This section describes functions which can only be enabled via switches
on the BAC-IP/50 circuit board.
5.1 Function Descriptions
Bank A-1: Auto-Detail
Off: Mode status reported as ‘Auto’, regardless of
which ‘Auto’ mode is active.
On: ‘AutoHeat’ or ‘AutoCool’ are reported, if
active.
Bank A-2: Preserve-Settings
Off: All BACnet object properties are initialised at
power-up.
On: All BACnet object properties except
Present-Value and Priority-Array are
initialised at power-up.
Also, all ‘Input’ object Present-Values are
stored in the Present-Value of the
corresponding ‘Output’ object.

Appendix B : Reset Button
The Reset button has 2 functions :
1) To restore various internal settings to their factory defaults,
2) To force the unit into ‘bootloader’ mode ready for a firmware
update.
Function 1 – Restore Factory Defaults
There are 2 levels to this function.
Level 1 : With the unit already ON, press and hold in the reset
button. After approximately 5 seconds the ‘Device Reset’
light will start to flash slowly. Releasing the reset button
while the light is flashing slowly will activate Level 1, and
then reset the unit.
Settings Restored:
Configuration via network Enabled
Level 2 : With the unit already ON, press and hold in the reset
button. After approximately 5 seconds the ‘Device Reset’
light will start to flash slowly. Continue to hold in the reset
button until the light starts to flash rapidly. Releasing the
reset button while the light is flashing rapidly will activate
Level 2, and then reset the unit.
Settings Restored:
IP Address 192.168.1.10
Gateway Address 192.168.1.10
Subnet Mask 255.255.255.0
G50 IP Address 192.168.1.1
BACnet Device ID 10
BACnet Device Name Procon BAC-IP/50
Foreign Device Reg TTL 1800

14
Function 2 – Enable ‘Bootloader’ Mode
Bootloader mode allows the firmware to be updated from a PC.
Press and hold in the reset button while powering up the unit. Continue
to hold in the reset button for approx. 5 seconds, until the ‘Device Reset’
light begins to flash ( Long ON, Short OFF ). The unit is now in
bootloader mode.
Note:Enabling the bootloader in this way is only necessary if the
firmware update software fails to automatically put the unit into
bootloader mode.

15
Appendix C : System Objects
There are 5 ‘System’ objects contained within the Procon BAC-IP/50. A
description of each is detailed below.
System Object Description
Mnet Comms State Provides an indication of the communication status
between the G-50 and the Mitsubishi M-Net network.
Inactive : M-Net Initialising
Active : M-Net OK
Note:While M-Net is initialising, the air-conditioning is
effectively offline to control and monitoring
requests.
System Forced Off (Setup) Writeable object to enable and disable the global on/off
command.
System Forced Off (State) Readable object giving indication of the global on/off
command.
G50 Comms State Provides an indication of the communication status
between the Procon BAC-IP/50 and the G-50.
Inactive : G-50 not responding
Active : G-50 comms OK
Note:‘G-50 not responding’ either means the G-50 is
switched off or is not connected to the network.
New_Setting_Compare Selects the way in which the Procon BAC-IP/50 handles
new command settings.
Inactive : New command values are written
regardless of the current setting.
Active : New command values are only written if the new
setting is different to the current setting.
(Useful for systems which continuously write to
the command parameters).
