Using Setup Mode for Configuration Hostlist Retrycounter (3) ? Hostlist Retrytimeout (250) ? DisConnMode (00) ? FlushMode (00) ? DisConnTime (00:00) ?: SendChar 1 (00) ? SendChar 2 (00) ? 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 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 device server 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 is 250. 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. 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. Typically, a modem is connected to a local PC, and a modem is 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 device servers 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), or D7 (echo with 1-character response). 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), or D7 (echo with 1-character response).

To enable the hostlist:
1.
Enter a Connect Mode of 0x20 (
2
X), where X is any digit. The menu shows you a
list of current entries 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 device server 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 is 250.
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.
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.
Typically, a modem is connected to a local PC, and a modem is 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 device servers 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), or
D7
(echo with 1-character response).
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), or D7 (echo with 1-character
response).
