6.2 CRC16 Calculation
Example code CRC16 calculation in C-language:
#define CRC_CONSTANT 0xA001
word Crc16 (byte* pb, byte len)
{
byte i;
word crc;
for (crc=0xffff; len--; pb++)
{
crc ^= (byte)*pb;
for (i=8; i--; )
if (crc & 0x01)
{
crc
>>= 1;
crc ^= CRC_CONSTANT;
}
else
crc
>>= 1;
}
// return crc result
return crc;
}
6. Protocol
This chapter describes the communication protocol between the IF SMI RS-485 module
and Host controller.

6.1 Message structure
[SID] [LEN] [CMD] [DATA] [CRC16]
SID
Slave ID
LEN Message length (without CRC)
CMD Command byte
DATA Optional data bytes
CRC16 16 bits checksum (LSB first)
The IF SMI RS-485 module has 4
DIP switches, which represents the base
address of the module from 0 to 15 (decimal)
or 0 to F (hexadecimal). The base address
is part of the Slave ID:
Base address Slave ID
0 0xC0
1 0xC1
2 0xC2
3 0xC3
4 0xC4
5 0xC5
6 0xC6
7 0xC7
8 0xC8
9 0xC9
10 0xCA
11 0xCB
12 0xCC
13 0xCD
14 0xCE
15 0xCF
6.3.1 MSG_UP
This message is used to move all, or a set of sun blind, to the top position.
Message: [SID] / [LEN] / [CMND] / [MSK0] / [MSK1] / [CRC16]
[MSK0]: LSB of 16-bit mask to select motor address 0..7.
[MSK1]: MSB of 16-bit mask to select motor address 8..16.
When bit n in mask is set, SMI motor with address n is addressed and
executes a UP command.
The IF SMI RS-485 module responds to this request with a general status
message MSG_GETGENSTAT.
The position of each sun blind can be obtained by the detailed response
message MSG_GETDETSTAT.
6.3.2 MSG_DOWN
This message is used to move all, or a set of sun blind, to the
lower
position.
Message:
[SID] / [LEN] / [CMND] / [MSK0] / [MSK1] / [CRC16]
[MSK0]: LSB of 16-bit mask to select motor address 0..7.
[MSK1]: MSB of 16-bit mask to select motor address 8..16.
When bit n in mask is set, SMI motor with address n is addressed and
executes a DOWN command.
The IF SMI RS-485 module responds to this request with a general status
message MSG_GETGENSTAT.
The position of each sun blind can be obtained by the detailed response
message MSG_GETDETSTAT.
6.3.3 MSG_STOP
This message is used to stop all, or a set of sun blind.
Message:
[SID] / [LEN] / [CMND] / [MSK0] / [MSK1] / [CRC16]
[MSK0]: LSB of 16-bit mask to select motor address 0..7.
[MSK1]: MSB of 16-bit mask to select motor address 8..16.
The IF SMI RS-485 module responds to this request with a general status
message MSG_GETGENSTAT.
The position of each sun blind can be obtained by the detailed response
message MSG_GETDETSTAT. The IF SMI RS-485 module responds to
this request with a general status message MSG_GETGENSTAT.
The position of each sun blind can be obtained by the detailed response
message MSG_GETDETSTAT.
