The Synthesized Netlink Radio Data System (SNRDS) is a radio system for transferring digital data between
physical locations where wire connections are impractical or too expensive. It incorporates an intelligent packet
controller, a fast, frequency synthesized data radio, and supporting I/O and indicators. One SNRDS unit, a power
source and antenna is required at each location requiring data communication.

source and antenna is required at each location requiring data communication.
SNRDS communicates with local equipment (a data terminal, host computer, or a specialized hardware device) via
an RS-232 data port. A second serial port is used for outputting special messages or as an addressable serial bus to
add-on modules. 1200 to 19200 baud is available on the link side (over the air).

About This Manual
These instructions are intended to enable the uninitiated to communicate via packet and to describe the SNRDS
thoroughly. Most of these instructions concern the software. It’s assumed that a non-intelligent computer terminal
or a computer having a simple terminal emulator program is available, allowing the operator to access the SNRDS
directly. Basic operation is simple, but the myriad of commands and options provided could be initially
overwhelming; learn the basic commands now and review the list of commands at leisure to develop an
appreciation for the capabilities provided. New commands can be studied in detail as required. Commands are
highlighted in the text (in boldface type) and are often referenced in the discussions. Where a command is
referenced instead of a section number, refer to the command summary in section 7.

Commands
.
Character conventions used are as follows: CR is a line-feed character, usually a RETURN or ENTER key on a
keyboard. LF is a line-feed, or ^J. Control characters are indicated in the text by preceding the character with “^”,
and are keyed in by holding the control key down while typing the character. All SNRDS commands are in
boldface type. The term “connection” appears in two contexts; one refers to physical connections via electrical
conductors, and the other to a “virtual” connection, which exists only in software. Confusion can be resolved by
assuming that when electrical wiring is the subject, it’s the former context; the latter applies when the only action
involved is in typing characters to the keyboard.
