Services Tab

TCP Client: If this option is selected, the device will act as a TCP Client and connects to the host processor once the serial port

becomes active.

TCP/UDP Independent Activation: This option determines if the TCP/IP port of the device will accept data before the

remote side (Serial Port) is active. At least one of the two sides in the configuration must be set for Independent Activa-

tion. If neither side is set, then the device will not accept data. This function provided integrity for the device by prevent-

ing data from being accepted until it can be delivered successfully. A TCP Server set to Yes, will listen even if the serial

side is not considered connected, If set to No, it will not listen for a connection until the serial side is considered con-

nected. A TCP Client set to Yes will always attempt to connect to the configured destination IP, even if the serial side is not

connected or active. If set to No, it will attempt a connection only when the serial side is first considered connected. The

recommended setting is Yes for Servers and No for clients.

TCP Headers: Select the TCP/IP Header Type (Message Length Field) required for TCP/IP communication from the drop-

down list. The available options for this field as shown below.

None: If this option is selected, the device will not add or remove any bytes as the length field from the data packets

received or transmitted.

Standard: If this option is selected, the device will add 2 bytes of binary exclusive network order to all transmitted

TCP packets, and will remove the 2 bytes from the received TCP packets.

Extended: If this option is selected, the device will add 4 bytes of binary exclusive network order to all transmitted

TCP packets, and will remove the 4 bytes from the received TCP packets. Extended header normally is used as an

indicator First, Mid and Last when dealing with the large TCP messages and possibility of TXP/IP packet fragmenta-

tion.

Host IP Address (Required): Enter the host destination IP Address into this field. This is required if the device is acting as

a TCP/IP Client.

Host IP Port (Required): Enter the host destination Port Address in this field. This field is required if the device is acting as

a TCP/IP Client.

Client Source Port: Enter the Source Port Address into this field This is required if the device is acting as a TCP/IP client

and using specific source port for TCP socket connection.

TCP Server: If this option is selected, the device will act as TCP Server and listen on the configured Listening IP Port for con-

nection from the client.
