Software Manual 122

Services Tab

Connect Mode: If this option is set to No, the device will expect to receive AT Commands in order to go to active state.

Some DTE (Data Terminal Equipment) devices required to go active if they provide DTR (Data Terminal Ready) signal.

The recommended setting for this field is Yes, if DTR is the connect signal.

Ignore DTR: This option needs to be set to Yes, if the serial port is connected to a DTE device that only provides 3 wires

(Transmit, Receive and Ground) for communication or the DTE device could drop DTR signal while sending AT com-

mands. The recommended setting for this field is YES

if 3 wires connection is expected.

Connection Type: Select the connection type you desire from the drop-down list. The recommended setting for this

field is Modem Emulator for direct connection.

Modem Emulator: Provided direct connection between the device serial port and the DTE terminal via straight RS232 cable.

Via Modem: This option is only used if the device provides TELCO/BPX or RJ11 To Terminal port for communication.

Use Timer Only: This option needs to be set to Yes in order to use the Inter Character Timeout value configured on this

device. The recommended value for this field is Yes

Inter Character Timeout (ms): When the timer expires on the serial port, the device will forward the message received

to the remote device. This option is used when there is no consistent character to signal the end of a received mes-

sage. This timer will be reset to the configured value on each received character. The recommended value for this field

is 5 milliseconds at 9600 baud.

Maximum Buffer Size: Set the maximum buffer size to be used for receiving serial data before forwarding to the

remote device. A value of 0 will allocate 8192 bytes of buffer by default and the data could be sent to the remote

application based on TCP stack window size. The recommended setting for this field is 292 for DNP3 type connections

and 0 for all other connections.

Enable Hardware Flow Control: Select Yes to set hardware flow control using RTS and CTS signals. The recommended

settings for this field are: No

if dealing with 3 wires port (Transmit, Receive and Ground pins), Yes if dealing with the

port that have all their signal pins present.

Number of Missed Polls Allowed: Set the maximum number of missed RTU polls before re-initializing all the internal

memory and buffer conditions. If a packet is transmitted out the serial port and no response packet is received, this is

counted as a missed poll and data content is not evaluated. The recommended setting for this field is 0, to disable this

action. Any other value is upon your environment requirements.

Socket Type: Select the Socket Type you desire to have for Serial IP communication from the drop-down list.

UDP: If this option is selected, the device will act as a UDP (Connectionless) and listening on the configured Listening IP Port

for connection for the client.

Peer IP Address (Required): Enter the peer IP Address into this field. This is required for UDP communication. This speci-

fies the Peer IP address and if set to 0.0.0.0 any remote IP can send UDP packets to our peer port, and return packets will

be sent back to the IP of the last host that sent a message. Packets cannot be sent until one is received first (to learn the

remote peer’s IP). If set to a specific IP, then packets will be sent to this IP only. The recommended setting for this field is

“0.0.0.0” to allow any IP to send packets to the peer import number. You also have the option to set a second, third,

fourth and fifth address in respective fields further below on the dialog window.

Peer IP Port (Required): Enter the peer Port number into the field. This is required for UDP communication. Consult your

network administrator for UDP applicaton destination port number. You also have the option to set a second, third,

fourth and fifth address in respective fields further below on the dialog window. You also have the option to set a second,

third, fourth and fifth port in respective fields further below on the dialog window.

Client IP Port (Required): Enter the client IP port number into this field. This is required if the peer IP Address is set to a

specific IP, then packets will be sent to specific IP at this client IP port number only. Consult your network administrator

for UDP application destination port number. Set to 0 if the Peer IP is set to “0.0.0.0”. You also have the option to set a

second, third, fourth and fifth port in respective fields further below on the dialog window.
