CN2610 User’s Manual Setting Up Raw UDP

Setting Value Notes Necessity

Dest. IP

address

1/2/3/4

Begin: x.x.x.x

End: y.y.y.y

Port: 1 to 65535

Defines 1 to 4 groups of IP addresses. UDP

packets will be sent through UDP port Port

to the range of IP addresses from the Begin

IP address to the End IP address.

Src. IP

address

1/2/3/4

Begin: x.x.x.x

End: y.y.y.y

Port: 1-65535

Defines IP addresses that will be allowed

to transmit UDP packets to CN2610’s

Ethernet port. UDP packets from IP

addresses in the range from Begin IP

address to End IP address will be accepted

through UDP port Port.

Local

Listen

Port

1-65535 The UDP port that CN2610 listens to and that

other devices must use to contact CN2610.

The default is blank. Be sure to choose a

Local Listen Port number that does not

conflict with the Local Listen Port for

CN2610’s other serial ports.

Required

Delimiter

1/2

<Hex>

00-FF Once the CN2610 receives delimiters

through its serial port (or the amount of

data received exceeds 1K), it immediately

packs all data currently in its buffer and

sends it out the CN2610’s Ethernet port.

Note: Delimiter 2 is optional. If left blank,

then Delimiter 1 alone trips clearing of the

buffer.

Optional

0-65535 0: Disable this function.

1 to 65535: Forces the CN2610 to try to

pack serial data received during the

specified time into the same data frame via

UDP mode.

Optional

Force

transmit

<ms>

The optimal Force Transmit timeout depends on the application, but it must be at

least as large as the time required to transmit one character, for the specified

baudrate. For example, assume that the serial port is set to 1200 bps, 8 data bits, 1

stop bit, and none for parity. In this case, the total number of bits required to send

a character is 10 bits and the time required to transfer one character is

( 10 bits / 1200 bits/s ) * 1000 ms/s = 8.3 ms.

Therefore, you should set the Force Transmit timeout to be greater than 8.3 ms.

The Force Transmit timeout is specified in milliseconds and must be larger than

10 ms.

If you want to send a series of characters in the same packet, the serial device

attached to CN2610 should send that series of characters during a time interval

less than the Force Transmit timeout, and the total length of data must be less

than or equal to CN2610’s internal buffer size. The serial communication buffer

size is 1 KB per port.
