Setup Mode: Channel Configuration

4.For Retrycounter, enter the number of times the WiBox should try to make a good network connection to a hostlist entry that it has successfully ARPed. The range is 1-15, with the default set to 3.

5.For Retrytimeout, enter the number of seconds the unit should wait before failing an attempted connection. The time is stored as units of milliseconds in the range of 1-65535. The default setting is 250.

d) Datagram Type

Directed UDP

When selecting this option, you are prompted for the Datagram type. Enter 01 for directed or broadcast UDP.

When the UDP option is in effect, the unit never attempts to initiate a TCP connection because it uses UDP datagrams to send and receive data.

e) Modem Mode

In Modem (Emulation) Mode, the unit presents a modem interface to the attached serial device. It accepts AT-style modem commands and handles the modem signals correctly.

Normally, there is a modem connected to a local PC and a modem connected to a remote machine. A user must dial from the local PC to the remote machine, accumulating phone charges for each connection. Modem Mode allows you to replace modems with the WiBox, and to use an Ethernet connection instead of a phone call. By not having to change communications applications, you avoid potentially expensive phone calls.

To select Modem Mode, set the Connect Mode to C6 (no echo), D6 (echo with full verbose), D7 (echo with numeric response), CF (modem responses only, numeric response), or CE (modem responses only, full verbose).

Note: If the unit is in Modem Mode, and the serial port is idle, the unit can still accept network TCP connections to the serial port if Connect Mode is set to C6 (no echo), D6 (echo with full verbose), D7 (echo with numeric response, CF (modem responses only, numeric response), or CE (modem responses only, full verbose).

Without Echo

In Modem Mode, echo refers to the echo of all of the characters

 

 

entered in command mode; it does not mean to echo data that is

 

 

transferred. Quiet Mode (without echo) refers to the modem not

 

 

sending an answer to the commands received (or displaying what

 

 

was typed).

 

 

 

 

Data Echo & Modem

Full Verbose: The unit echoes modem commands and responds to

 

Response

a command with a message string shown in the table below.

 

 

Numeric Response: The unit echoes modem commands and

 

 

responds to a command with a numeric response.

 

 

 

 

Modem Responses

Full Verbose: The unit does not echo modem commands and

 

Only

responds to a command with a message string shown in the table

 

 

below.

 

 

Numeric Response: The unit does not echo modem commands

 

 

and responds to a command with a numeric response.
