8 Serial Protocol

The 840Hxl can be controlled via the serial port using the commands described in this section. The following table shows the default communication parameters.

RS-232
Baud Rate:	9600
Data Bits:	8
Stop Bits:	1
Parity:	None

8.1 Command Format

Commands must be in the following format:

0xEB, address, command, length of data, data 1, ...data n, checksum where the following table describes the command components.

Command Component	Description
0xEB	Fixed command start byte
address	Device address. This is always 0x90 for the 840Hxl
command	Command to be sent
length of data	How many bytes sent/received (from data 1 to data n)
data 1, data n	One or more command variables within the range 0x01 to 0xFA and excluding 0xEB
checksum	Optional—Checks whether the sending/receiving frame is valid.Check sum = Address + Command + Data length + Data 1+...+Data nFor example, EBH, 90H, 01H, 01H, F3H, 85HCheck sum = 90H + 01H + 01H + F3H = 185HNote: The checksum gets the low 8 bits, for example, if the check sum = EBH, then check sum = 14H

8.2 Device Response

The device responds as follows:

0xEB, 0x90, command, 0x01, answer, check sum

where answer is one of the values described in the following table.

Command Component	Description
0xF1	Either:–the device received the wrong address and returns no response–the device gets information about Errors and Alarms
0xF2	The data is out of range. The command is not executed
0xF3	The device is currently controlled by the buttons. The command is not executed
0xF7	The data length is incorrect. The command is not executed
0xFC	The data is out of range. The command is not executed

8.3 Commands

The commands listed below are supported by the 840Hxl.

Note: A checksum is required at the end of the send/receive command as shown in Section 8.1. If a checksum is not included in a sent command, the device does not respond.

8.3.1 Get Device Address and Software Version
