RS-232 connector (optional) — Connect a host computer or control system to the
E
RS-232 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 rate, no parity bit, 8 data bits, 1 stop bit, and no flow
control (handshaking).
For information on SIS commands, see

page 57.
See figure 7 below, to wire the RS-232 connector.

Reset button and LED — The reset button is used to return the SMD 101 to partial
F
or complete factory condition. The reset LED provides the status of the reset. The
SMD 101 has three reset modes (see
page).
RJ-45 LAN connector — Connect one end of an RJ-45 cable to the LAN (Ethernet)
G
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.
