Introduction

The LAN-Modem permits devices that require dial-up modems for communicating to use the Intranet or Internet instead of the telephone system. On a serial interface, the LAN-Modem behaves in a way this is compatible with standard modems for the telephone system; the only difference is that the dial-up number is replaced by an IP address.

W&T Connections and Displays

2.1 Ethernet connection

The location of the LAN-Modem must be selected such that on the network side a maximum cable length of 100 meters is not exceeded.

For the network connection, an IEEE 802.3 compatible terminal on a shielded RJ45 plug is provided on the front panel. With a shielded patchcable the LAN-Modem can be connected through here to a hub or switch. Pin assignments conform to a standard MDI interface (AT&T258), so that you can use here a 1:1 cable with a length of max. 100 meters.

2 = Tx-

3 = Rx+

4 = nc 5 = nc

6 = Rx-

7 = nc

8 = nc

RJ45-Buchse (Belegung AT&T256)

Depending on the LAN-Modem model, the following standards are supported:

10BaseT (Typ 58210, 58610)

These devices operate conformal with the 10BaseT standard at 10MBit/s. It is also possible however to link into a 100BaseTx network using an autosensing hub or switch. Such an autosensing component automatically adjusts to the transmission rates supported by the terminal device.

10/100BaseT autosensing (Models 58220, 58620)

These devices support both 10BaseT as well as the 100BaseTx standrad at a bit rate of 100Mbit/s and offer full-duplex transmission. Switching between the two network speeds is done using the autosensing function of the LAN-Modem according to the capabilities of the hub or switch used. The prerequisite for operating at

100MBit/s is appropriate cabling (Cat 5/ISO Class D or better).

The current link status is indicated by the Error LED on the front panel: If it blinks at 1-2 second intervals, there is no connection to the hub, or the connection is faulty.

W&T Connections and Displays

2.2 The RS232 connection

The pin assignments for the RS232 port are identical with that of a dialup modem, which means that standard cable can be used. Make sure that the prots for the LAN-Modem and the serial terminal device are configured for identical transmission parameters and handshake procedures.

2.3 Supply voltage

Depending on the hardware version, the LAN-Modems are supplied either with a regulated +5V or with an AC/DC voltage of between 12V and 24V.

2.3.1 5V supply voltage (58210, 58220)

The supply voltage for models 58210 and 58220 is brought in through the power terminal located on the underside of the housing. The supply voltage is 5V +/5%. The current consumption of the various models can be found in the technical appendix.

2.3.2 12–24V supply voltage (58611, 58620)

The supply voltage for models 58610 and 58620 can also be brought in through the power terminal for jack plugs located on the housing underside. Both DC voltage of any polarity as well as AC voltage may be used. Polarity versal protection results in the following maximum and minimum values for the supply voltage:

 AC: 9Veff (-5%) – 24Veff (+5%)  DC: 12V (-5%) – 34V (+5%)

The current consumption of the various models can be found in the technical appendix.

W&T Connections and Displays

2.4 LED displays

Status and error information is indicated by the LAN-Modem using three LEDs having various blink codes.

• Power-LED

Indicates the presence of supply voltage. If the LED is not full on, please check your power supply connections.

• Status-LED

Flashes when there is network activity with the LANModem. Periodic flashing indicates that the port has a connection to another station.

• Error-LED

The error LED uses various blink codes to indicate error states on the device or serial port: 1 xflashing = Check network connection

The LAN-Modem is not receiving a link pulse from a hub. Check the cable and hub.

2 x fhashing = Check serial basic configuration

Use the Telnet configuration to check the basic settings of the LAN-Modem for Port 0:

SETUP Port 0 (serial) r UART Setup r Baud = 57600

SETUP Port 0 (serial) r UART Setup r Parity = NONE

SETUP Port 0 (serial) r UART Setup r Data Bits = 8

3 x flashing = Check serial basic configuration

Use the Telnet configuration to check the basic settings of the LAN-Modem for Port 0:

SETUP Port 0 (serial) r UART Setup r Handshake = HARDWARE

All LEDs on = Self-test error

The self-test performed after each start or reset of the LAN-Modem could not be correctly finished due for example to an incomplete update of the firmware. In this state the LAN-Modem is no longer operational. Please return the unit for repair.

For additional informatio on the settings, please refer to section 4 „Modem Operation“

3 TCP/IP Configuration

Following the hardware installation, this section describes the logical

integration of the LAN-Modem into the TCP/IP network.

■ Assigning the IP address

■ Setting the Subnet-Mask and Gateway

You can obtain all the parameters from the system administrator of

your network. In contrast to the IP address, which is always required,

you may skip the setting of the subnet mask and gateway if the

communications partner for the LAN-Modem is located in the same

network.

W&T TCP/IP Configuration

3.1 Assigning the IP using the „ARP“ command

This method can only be used if the LAN-Modem does not yet have an IP address, i.e. the current entry is

0.0.0.0. To change an IP address, use one of the other methods described in this section or use the configuration menu via TELNET.

The prerequisite is a computer located in the network segment of the LAN-Modem and which has TCP/IP protocol installed. Read the Ethernet address of the LANModem off from the sticker on the side of the housing:

58xxx [Model]

EN=00c03d004a05

OK xxxxxx

Ethernet address

Now use the following command line of the ARP table in your computer to add a static entry:

arp -s [IP address] [MAC address]

Example under Windows:

arp -s 172.16.231.10 00-C0-3D-00-12-FF

Example under SCO UNIX:

arp -s 172.16.231.10 00:C0:3D:00:12:FF

Then use the following command line under Start

→

Run

to start a Telnet session to the configuration port of the LAN-Modem with the desired IP address:

telnet 172.16.232.10 1111 [Return]

In Windows environments you must enter the IP

address without leading zeros. Otherwise the entry will be improperly interpreted by the system and the LANModem will assign an incorrect IP address.

Older Windows systems will only accept a static entry if a dynamic entry was already present. First send a PING to another network station.

W&T TCP/IP Configuration

Subject to error and alteration

Every IP address must be used only once in the network.

The LAN-Modem accepts the IP address of the first network packet sent to it as its own and saves it in non-volatile RAM. Only now is the Telnet connection established and the configuration menu shown in the Telnet window. Now you may sete the subnet mask and gateway (see section 3.5 Configuring the subnet mask and gateway).

W&T TCP/IP Configuration

3.2 Assigning the IP through the serial port

After the LAN-Modem has been reset, a time window of approx. 1-2 seconds is provided during which you can assign a new IP address by entering at least three „x“.

In contrast to the previously described using ARP, this serial path works regardless of whether the LAN-Modem already has an IP address or not. The procedure can be repeated as often as desired. This method is therefore recommended if you do not know the IP address or have forgotten it.

First connect the serial port of the LAN-Modem to a computer. For a standard PC or a laptop, you will require a 1:1 modem cable (see section 2.2 The RS232 connection).

The serial transmission parameters of the terminal program used are configured for 9600 Baud, no Parity, 8 bits, 1 stop bit, no handshake. Interrupt the supply voltage to the LANModem to perform a reset. If the green Status LED comes on, enter the letter „x“ at least three times on the terminal until the LAN-Modem has returned the prompt „IPno.+<Enter>:“.

Use the usual format (xxx.xxx.xxx.xxx) to enter the IP address and finish your entry by pressing <Enter>. If the entry was accepted, this is acknowledged with the assigned IP address. Otherwise a „FAIL“ message is returned with the last current IP address.

All other settings such as the gateway address, subnet mask, etc. are made using the Telnet configuration menu (see section 3.5 Configuring the subnet mask and gateway).

W&T TCP/IP Configuration

Subject to error and alteration

3.2.1 Serially deactivating the DHCP-/BOOTP-Client

The DHCP-/BOOTP function of the LAN-Modem can be turned off when serially assigning the IP address. We recommend doing this in all cases where it is not absolutely necessary to use DHCP/BOOTP to assign the IP.

To deactivate the DHCP-/BOOTP client, attach the option „-0“ directly after the IP address (no spaces) and confirm your entry with <Enter>.

Example:

xxx -> Com-Server IP no.+<ENTER>: <- Com-Server

172.17.231.99-0 -> Com-Server

172.17.231.99 <- Com-Server

You can always reactivate the function later using the Telnet configuration under SETUP System
