3.6 Dip Switches
A double DIP switch allows theMLB-S4101 to be placed into Console/Loop back/Default/Data Mode.
SW1 SW2 Mode
ON ON Console
ON OFF Loop back
OFF ON Factory
OFF OFF Data
When all these switches are moved into the ON position, theMLB-S4101 enters Console Mode, allowing configuration of
theMLB-S4101 from a PC running a terminal program such as Hyperterminal. When theMLB-S4101 enters Console Mode,
the Console Mode screen will appear in the Hyperterminal program window. The serial port settings must be 8-N-1 at
9600 baud.
When the DIP switches are switched to the ON OFF position, the MLB-S4101 will work at Loop back Mode, all data is
sent back immediately.
When the DIP switches are switched to the OFF ON position, the MLB-S4101 will revert to its factory version firmware no
matter what newer firmware has been upgraded.
When all of the DIP switches are switched back to the OFF position, the MLB-S4101 will enter Data Mode (RS-232, RS-
422 or RS-485).
3.7 Serial Ports
The MLiS-S4101 has one serial port. The port can be configured as a Console Mode connection or as RS-232, RS-422 or
RS-485 interface to the MLiS-S4101 (if all of the DIP switches are in the OFF position) using the Manager software, via
Telnet, or using the Web Server.
The RS-232 interfaces are configured as DTEs (Data Terminal Equipment). The connectors for all ports are DB-9M.
3.8 Serial Server/Port Operational Modes
Using the Manager software, the MLB-S4101 serial server can be put into Console Mode, Default Mode or Upgrade Mode.
The serial ports can be configured for RS-232, RS-422 or RS-485 operation. The MLB-S4101 serial server also can be
put into Console Mode by placing all the DIP switches into the ON position.
3.8.1 Console Mode
The console mode allows access to the MLB-S4101 setup menu. This is one way to reconfigure the default settings for
the application. A serial connection is made between a COM port on the PC and the MLB-S4101 serial port 1 with a null
modem cable. In console mode, the serial port defaults to an RS-232 interface.
The MLB-S4101 serial port default settings are, baud rate 9600, 8 data bits, no parity, and 1 stop bit. Hyper Terminal
should be used for this type of setup. Hyper Terminal’s serial settings are configured the same as the mentioned default
settings of the MLB-S4101 and must be set to VT100 emulation mode. The default settings are used only if they have not
been changed.
See Chapter 10 for details.
3.8.2 Upgrade Mode
The newest firmware can be installed on the MLB-S4101
using the PC’s serial port or the Virtual COM port.
See Chapter 13 for details.
