3.2 Serial Port Configuration
Command Description
BAUD x :
(1200|…|
115200)
Configures the baud rate of the X port.
• Values = 1200, 2400, 4800, 9600,
9600, 9600,
9600, 14400, 19200, 28800, 38400, 57600 or
115200..
Example of use:
BAUD A :115200
BITS x :
(7|8)
Configures the data bits of the X port.
• Values = 7 or 8.
Example of use:
BITS
B
:7
PARITY
x
:
(N|E|O)
Configure the parity of port X.
• N = NONE - / = EVEN - (Even Parity) /
O = ODD - (Odd Parity)
Example of use:
PARITY C :E
STOP x :
(1|2)
Set the stop bits for the X port.
• Values = 1 or 2.
Example of use:
BITS
B
:2
PROTOCOL
x
:
(R|A)
Configure Modbus type of port X.
• R
RR R = Modbus RTU / A A A A = Modbus ASCII
Example of use:
PROTOCOL A :R
PKTTOUT
x
:
(3..50)
[Bytes Time]
Modbus RTU packet expiration time for port X.
• Value = 3 ... 50 [Bytes Time].
Example of use:
PKTTOUT
D
:4
EXCEPTION
x
:
(E|D)
Enable or Disable the exceptions for port X.
• E = Enabled / D = Disabled
Example of use:
EXCEPTION A :D
WPROTECT
x
:
(E|D)
Enables or disables write protection of Modbus registers for the master connected
to the port X.
• E = Enabled / D = Disabled
Example of use: WPROTECTB
BB B:D
PKTTOUT - Modbus RTU packet expiry time: Modbus RTU packets are separated
from each other by a time interval. This parameter allows you to change the
maximum time to count after the last byte of the packet is received, during which
the SGW1-IA3-MMP will assume that the packet has not yet been terminated.
After this maximum time, the SGW1-IA3-MMP will assume that the packet has
finished arriving. The time is entered in one-byte time units, with a minimum of 3
units.
