RS-232 connector (optional) — Connect a host computer or control system to the
3-pole, 3.5 mm captive screw connector or to the local device if pass-through mode
is used. Use this port to send SIS commands to the SMD 101 for device configuration
and control. The default protocol for this port is 9600 baud, no parity bit, 8 data bits,
1 stop bit, and no flow control (handshaking).
• For information on SIS commands, see
Remote Communication and Control
on
page 111.

Reset button and LED — The reset button is used to return the SMD 101 to partial
or complete factory condition. The reset LED provides the status of the reset. The
SMD 101 has three reset modes (see
SMD 101 Rear Panel Reset on the following
page).

RJ-45 LAN connector — Connect one end of an RJ-45 cable to the LAN (Ethernet)
connector on the SMD 101 (see figure 8). Connect the other end of the RJ-45 cable to
a router or switch to connect the SMD 101 to a network.

Figure 8. RJ-45 Ethernet Connector
The LEDs on the Ethernet connector indicate the status of the network connection.
• Link LED — This green LED lights when the SMD 101 is properly connected to an
active network.
• Act LED — This amber LED blinks in a pattern to indicate the connected network
speed as follows:
• Three blinks — 1 Gbps
•
Two blinks
—
100 Mbps
• One blink — 10 Mbps
