Understanding the Lantronix MSS100
The MSS can be used to start outbound Ethernet connections to hosts on TCP/IP, IPX/SPX and LAT networks. It can also provide interactive access to a device connected to its serial port.
The MSS has three components.
- The Power cord
- A typical Ethernet cord
- A serial cable: one end being “DB 25 female”, the other end being “DB 9 female”.
Setting up your Lantronix MSS100
- If you have any questions about these settings you can find the user guide download here MSS100 guide.
- Install puTTY from here; puTTY downloads.
- Assuming that you haven’t assigned an IP address, follow these steps to do so.
- Connect the serial port from your MSS100 to the back of your computer. Also, connect the MSS100 to your network with an Ethernet cord.
- Open “Putty” and click on the “Serial” button and hit enter.
- This will open a putty session to the MSS. You should see a login prompt similar to the image below.
- Type the command “SET PRIVILEGED”. For the password use the default password which is “system”.
- Type in the command
“CHANGE IPADDRESS <IpAddressHere>”.
Note: Ensure that nothing else on your network has the same IP address or you will possibly knock it offline!
- Next we will want to configure the MSS’s subnet mask and domain. Type in the commands
“CHANGE SUBNET MASK <YourSubnetMask>”
“CHANGE DOMAIN <YourDomian>”
- Next we want to change the gateway that the MSS will use. Type in the command
“CHANGE GATEWAY <YourGateway>”
- At this point we want to control incoming logins to the MSS. I want to allow only Telnet logins and disable “LAT” logins. Type in the commands:
“CHANGE INCOMING NONE”
“CHANGE INCOMING TELNET”
- To add a bit more security to the MSS, I am going to require a password at login. Type the command:
“CHANGE INCOMING PASSWORD”
- Next disable the IPX Parameter, with this command:
“CHANGE NETWARE DISABLED”
- Here is a list of recommended settings for the MSS100.
All the commands (SET PRIVILEGED must be done first for these to work):
CHANGE IPADDRESS <IpAddressHere>
CHANGE SUBNET MASK <YourSubnetMask>
CHANGE DOMAIN <YourDomian>
CHANGE GATEWAY <YourGateway>
CHANGE INCOMING NONE
CHANGE INCOMING TELNET
CHANGE INCOMING PASSWORD
CHANGE NETWARE DISABLED
CHANGE SNMP DISABLED
CHANGE FTPSERVER DISABLED
CHANGE RARP DISABLED
CHANGE DHCP DISABLED
CHANGE BOOTP DISABLED
CHANGE WINS DISABLED
CHANGE SPEED <BAUD>
CHANGE FLOW CONTROL < CTSRTS, NONE, XONXOFF >
CHANGE PARITY < EVEN, MARK, NONE, ODDSPACE >
CHANGE CHARSIZE <# of bits>
Note: To see the changes you have made use the command:
Note: If you need the 'break' key to send out through the serial port to a connected device, you must run the command:
CHANGE BREAK REMOTE
Note: If the connection doesn't work, it's worth adding a null modem adapter during diagnosis, this is a common problem.
Testing the MSS100
A managed switch provides a good opportunity to test the MSS100 serial connectivity.
- Connect the MSS100 to your network via Ethernet.
- Connect a serial cable (DB 9) to the testing switch, and connect the other end to the MSS (DB 25).
- Connect Power to the MSS.
- When everything is hooked up correctly it should look something like this.
Connecting to the MSS100 Serial Port via IP
- Open puTTY.
- Under Host Name, enter the IP Address of the MSS.
- We will be preforming a “Telnet” connection, change the “Port” to 2001. Your settings should look similar to the image below.
- When you have achieved a successful connection, putty will open a cmd that looks something like this depending on your test switch.
