Data Interface Specifications: Serial, Ethernet & USB
Ethernet Port
The modem's 10/100Mbps Ethernet port is compliant with the EIA-568 standard. The modem's ports are auto-
sensing so they can be used with either a straight or crossover RJ45 cable to connect to host ports.
The BT/SN/RAM-6x21 features a 5-port Ethernet switch allowing connectivity to multiple local devices.
USB Device Port
This is a USB 2.0 Device interface on a Mini B (BT/SN/RAM-6xxx) connector. It offers Ethernet-over-USB functional-
ity using the RNDIS driver for Windows 7, Windows XP and Windows Vista Operating systems only. The RNDIS
driver must be installed before the USB interface can be used. The driver and instructions can be obtained by con-
tacting a Technical Support representative.
Serial Port (DB9)
Our BT/SN/RAM modems have a standard RS232 DCE, serial interface with a DB9 connector style. The modems
are DCE (Date Communication Equipment) devices and are compliant with EIA-232 standard.
Connect a DTE device to a DCE device using a straight pin-for-pin connection cable. To connect two DCE devices,
use a null modem cable which crosses the ‘transmit’ and ‘receive’ lines in the cable. An example of a DTE device is
a computer. Most other devices are DCE types.

* Depending on Serial Application
** There are 2 scenarios where all of the panel LEDs will flash rapidly: during a device firmware reflash and
during a module firmware reflash.
