CoolMasterNet
Universal Interface Adapter
for HVAC Systems

1. During the HVAC system automatic operations the CoolMasterNet must be disconnected from the system.
Examples of the automatic operations are:
· Test
· Reset
· Automatic charge
2. Do not change the original positions of the quadruple dip switch S inside CoolMasterNet when using it with
VRV/VRF systems.

4.1 HVAC Lines
CoolMasterNet supports eight HVAC Lines labeled as L1 ... L8 (see Layout), intended for connection to various
HVAC systems. All eight HVAC Lines can be used simultaneously (except L1 with L5 and L2 with L6) and
independently according to CoolMasterNet configuration. Most of the HVAC Lines capable to support a number
of HVAC Types as specified in table below, but one at time, according to configuration of the specific Line.

CoolGate 5 Indoors Address Map:
In order to simplify translation of the UID (like L1.100) into ModBus object address, CoolMasterNet uses VA,
associated with UID. Hex and Dec numbers printed after va command are Base Address used to access
ModBus objects related to UID-VA association. Base Address can be calculated as BaseAddress = VA*16 + 1.
For example Indoor Unit L1.100 has associated VA = 007, thus Base Address = 7*16+1 = 113 (0x71).
Once the Base Address is determined, access to the specific Indoor Unit parameter(s) is done via Modbus
objects listed below.

There is a possibility to read/write holding registers of several indoors by one request. If the read request started
from one of the readable registers (not reserved) the values of reserved registers will be 0xFFFF in the
response. If the read request started from reserved register the response will be illegal data address. In a similar
way it works with the write request. If the write request started from one of the writable registers (not reserved)
the values that were intended for reserved registers will be ignored. If the write request started from one of the
reserved registers the response will be illegal data address.

are linked into one line with option to auto-detect line polarity. Otherwise, if both P1 and P2 are in OFF
position HVAC Lines L6 and L7 are separate independent lines.
·If L6 and L7 are linked into L7, enabling of the L2 with P3 will not influence on L7 operation.
·Switch P4 must be in OFF position for normal operation of CoolMasterNet.

ASCII I/F
CoolMasterNet PRM Rev 0.7 16
www.coolautomation.com © 2017 CoolAutomation
6 ASCII I/F
CoolMasterNet provides a simple and comprehensive ASCII I/F Protocol, based on text (ASCII) strings,
representing verbal commands and responses . ASCII I/F implemented in CoolMasterNet is fully backward
compatible with previous versions of CoolAutomation products, but has a number of significant extensions and
improvements mainly aimed to support additional CoolMasterNet functionality. ASCII I/F can be utilized via
RS232 interface (see RS232 Port) or TCP/IP Server.
6.1 General Protocol Definitions
6.1.1 Messaging
Communication between DTE and CooLinkNet via ASCII I/F is based on text (ASCII) strings. Communication
example is shown below
>ls L2
çcommand
DTE to CooLinkNet
L2.102 OFF 20C 27C Auto Cool OK - 0
L2.103 OFF 20C 24C Low Auto OK - 0
çresponse
CooLinkNet to DTE
OK
çexit code
>
çprompt
Command string sent to CooLinkNet must be terminated with <CR> (carriage return 0x0D) <LF> (line feed
0x0A) sequence or a single <CR> character. Strings from CooLinkNet (except prompt character) are always
terminated with <CR> <LF>. Commands are case sensitive and should not contain leading or trailing spaces.
The only separator between command name and command parameter(s) is space (0x20) character.
Configuration parameter echo (see set command), defines if characters sent to CooLinkNet via RS232 interface
are echoed back or not. If echo is not zero - characters are echoed.
In case of RS232 interface, prompt character '>' is unconditionally sent by CooLinkNet. In case of ASCII Server
prompt sending is configurable.
6.1.2 Exit Code
CoolMasterNet provides Exit Code in verbose or numeric form. Numeric form format is
ERROR:N
where N is a number in range 0...999. If verbose format is not specified in table below it means error has only
numeric format.

Line
Dot
Indoor Number
Ln
.
X
YY

ASCII I/F
CoolMasterNet PRM Rev 0.7 18
www.coolautomation.com © 2017 CoolAutomation
·Line is a CooLinkNet HVAC Line number in range L1..L4. L* means "any line". In some cases to provide
backward compatibility Line can be omitted from the UID.
·Dot is a separator between Line and Indoor Number. If Line is omitted or has a L* form, dot must also be
omitted.
·Indoor Number is an Indoor Unit number in HVAC system. Indoor Number can be '*' that means "any"
Examples:
L1.102
Indoor Unit 102 on line L1
L2.003
Indoor Unit 003 on line L2
L*100
Set of Indoor Units 100 on all lines
L3.1*
Set of Indoor Units 1xx on line L3 (L3.100, L3.101, ... )
L4
All Indoors on line L4
L*
All Indoors on all lines
203
Similar to L*203 (for backward compatibility only)
UID_STRICT
In some cases only specific Indoor Unit should be referenced by UID. In this case it is required to use
UID_STRICT in format Ln.XYY where '*' usage is prohibited.
6.2 Commands Reference
Synopsis and description of the commands listed below have the following notation:
·Parameters or parameters group in angle brackets < > are mandatory.
·Parameters or parameters group in square brackets [ ] are optional and can be omitted.
·The curly braces ( ) are used to denote group inside braces
·The |character between parameters inside brackets means OR.
