2.1 Mechanical and Electrical Specification

RS232 Interface connector used in Cool Master is D-Type 9-pin DB9 female connector. Cool Master DB9 Connector front view

RS232 Interface

5

Connecting Cool Master to Home Automation Equipment

In the picture above it is assumed that Terminal Equipment DB9 connector has RxD line on pin 2 and TxD line on pin 3. (This is a standard for PC). If a Terminal Equipment (Home Automation Controller) has a reversed pin out ( RxD on pin 3 and TxD on pin 2), the crossed RS232 cable must be used to connect TxD to RxD and RxD to TxD.

According to RS232 specification cable length should not exceed 25m. RS232 Cable supplied with Cool Master is 1.5m length suitable for direct connection to PC RS232 serial port.

3 General Protocol Definitions

3.1 Message format

Communication between PC or Home Automation Controller and CoolMaster via RS232 interface is based on text messages. Communication example is shown below

Command message sent to CoolMaster must be terminated by CR (carriage return 0x0D) LF (line feed 0x0A) sequence or a single CR character. Messages from CoolMaster (except prompt character) are terminated by 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 character.

In case of wrong command CoolMaster response can be one of the following strings:

General Protocol Definitions

7

If command was executed CoolMaster will return optional response and exit code. Detailed information is provided in topics describing specific commands.

3.2 Indoor Unit Addressing

To address specific indoor unit the UID parameter is used in CoolMaster commands. UID format is three characters. First character is hexadecimal digit in range 0-9 or A-F to represent system numbers 0-9, 10-15 correspondingly or Z to specify centralized address mode.

UID Format:

· For CoolMaster 4000M System Number must be 0, Unit Number must be 01-50

· For CoolMaster 1000D System Number must be in range 1-4

· For CoolMaster 2000S, 3000T, 7000F,8000I(MH), 9000H System Number should not be 0

· For CoolMAster 6000L System Number must be 0, Unit Number must be 00-FF

· For CoolMaster G Unit Number must be in range 01-16

UID reflects the indoor unit address. For proper operation of CoolMaster all indoor units have to be given addresses (depending on specific AC system type this can be done automatically by system or has to be done manually by integrator). You should refer to specific AC system manuals to find out how to set and quire indoor unit addresses.

Below are examples of accepted UID's.

UID format for Centralized Address mode:

Example:

Centralized Address mode is currently supported for CoolMaster 2000S and 3000T.

Note: For backward compatibility Unit number in System can be represented by hexadecimal numbers couple in range 00-0F equal to decimal 00-15. For example 10A represents Centralized Address 1-15. We recommend not to use this option in future designs.
