SD Series Technical Manual
MDS 05-4846A01, Rev. F
•
Radio Mode
—The radio can operate in one of several modes. The
available selections are: Packet, Packet with MAC, x710, and
Transparent.
•
User Interface
—This parameter selects the method of radio man-
agement. The default selection is
Menu
, which presents the type of
screens shown in this manual. Alternatively, you may select
CLI
,
which switches the radio to a Command Line Interface. With a
CLI interface, commands are entered in text-based fashion, as
described in the
SD Serial/Telnet Management Supplement
, Part
No. 05-6193A01 more information.
Packet Settings
•
COM1/COM2 Port Inter-Packet Gap
—Timing setting used to delimit a
packet on the serial interface for radios operating in Packet Mode.
Too short of a time can cause serial streams to be combined into
one large packet instead of two smaller ones. Too long of a time
can effectively slow down the communications channel. The
Inter-Packet Gap is specified by the number of character times
(the time it takes to send an individual character).
•
Transparent RX Timeout (ms)
—This setting is similar to the timing
parameters for
COM1/COM2 Inter-Packet Gap
, but it applies to data
received
over-the-air
. It tells the radio how to build an Ethernet
packet based on a transparent data stream received over the radio
channel.
Media Access
Control
•
Device Type
—Selects
Access Point
,
Remote
, or
Store and Forward
. An
Access Point serves as the Controller of the RF network. Only one
radio is configured as an AP. Typically this is the “polling mas-
ter.” A
Remote
is connected to end devices in the field (
e.g.
PLC,
RTU), and there can be any number of these in a network. Each
