the GW-7238D
The IP information format of the GW-7238D is given as follows:
● Group-ID of 5-digit LED: 11111
● LED-1: Indicator, can be 1 or 2 or 3 or 4 for 4 sections of IP
address
● LED-2~5: IP address
The LED shows Group-ID first, and then shows its IP address as the
figure 2.14. If users change the IP address, the value shown on the LED
will be changed immediately. The default IP address is 192.168.255.1 and
the LED-show sequence is given as above diagram.
The configurations of the COM 1/2 and CAN port are given as follows:
● Group-ID of 5-digit LED: 22222
● LED-1: COM1 / COM2 Baud rate, this value needs to multiply by
1000. The range is from 9.6~115.2 (means 9.6 kbps ~
115.2 kbps)
● LED-2: Parity bit, 0=no parity, 1=odd parity, 2=even parity
● LED-3: Data bit, fixed at 8
● LED-4: Stop bit, 1 or 2
● LED-5: CAN Baud rate, this value needs to multiply by 1000. The
value is fixed at 250 (means 250 kbps)
The configuration of the communication is given as follows:
● Group-ID of 5-digit LED: 33333
● LED-1: Indicators, fixed at 1
● LED-2, 3: fix string, "id."
● LED-4, 5: The Modbus station ID of the GW-7238D
The connection-client information is given as follows:
● Group-ID of 5-digit LED: 44444
● LED-1: Indicators, fixed at 1
● LED-2, 3: Total supported socket numbers (5 sockets)
● LED-4, 5: Numbers of sockets are used by clients, default 0
If any client connects to the GW-7238D, the numbers of the used-
socket will be increased. The GW-7238D allows 5 clients for connection.
