Page 46

7: Setup Mode: Channel Configuration

To enable the hostlist:

1.Enter a Connect Mode of 0x20 (2X), where X is any digit. The menu shows you a list of current entries already defined in the product.

2.To delete, modify, or add an entry, select Yes. If you enter an IP address of 0.0.0.0, that entry and all others after it are deleted.

3.After completing the hostlist, repeat the previous step if necessary to edit the hostlist again.

4.For Retrycounter, enter the number of times the Lantronix unit 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 UDS1100s, 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).
