Serial Ports
Each of the two or four serial ports is configured as a DTE port using a male, DB9 connector.
This configuration is similar to that used on the COM ports of an IBM-compatible PC. The
following figure shows the pin configurations of these ports:

DL100 DB9 Pin Out
The two most important connections are the Receive Data line on pin 2 and the Signal Ground on
pin 5. When receiving serial data, these are the only two connections that the DL100 needs.
However, if either pass-through access to any connected serial devices or serial command line
access is required, then the transmitted data signal line on pin 3 must be connected as well.
Additionally, some equipment may require an RS-232 high signal on one or more of its signal
lines in order to transmit or accept data. Consult the manual for any connected equipment as
needed.
The DCE DB9 female cable end which mates with the serial port connectors of the DL100 will
often have a pair of screw-down cable locks. These cable locks should be used to assure a solid
connection of the cable with the DL100 serial port connectors.
Default settings for the serial ports are 19200-baud, 8-bit word length, no parity, and one stop bit
(19200, 8N1). Use either the internal setup menu or the external Dipswitches to adjust these
settings.
Ethernet
The Ethernet 10BaseT connector is a standard RJ-45. This standard connector will connect the
DL100 to an Ethernet hub or switch.
Internal Modem
If a dialup modem is installed, an RJ-11 (typical U.S. phone) connector is used. A POTS (analog)
dialup phone line is inserted into this connector. Depending on the model of modem installed, one
or two RJ-11 connectors may be present on the back panel. In the latter case, one will be labeled
‘phone’ and the other ‘line’. Connect the dialup phone line to the connector labeled ‘line’.
The modem installed within this unit is FCC certified. For further information, consult Appendix
B, or the serial number label on the bottom of the DL100.
