Lantronix UDS1100 - Manual (Page 47)

7: Setup Mode: Channel Configuration
UDS1100 User Guide 47
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, the prompt requests 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).
