XStream-PKG-R™ RS-232/485 RF Modem – Product Manual v5.x00

5. RF Communication Modes

Network configurations covered in this chapter are described in terms of the following:

• Network Topology (Point-to-Point, Point-to-Multipoint or Peer-to-Peer)

• RF Communication Type (Basic or Acknowledged)

• RF Mode (Streaming, Repeater, Acknowledged or Multi-Streaming)

The following table provides a summary of the network configurations supported.

Table 5.1. Summary of network configurations supported by the XStream RF Modem

Point-to-Point

Definition

An RF data link between two modems.

Sample Network Profile *

(Broadcast Communications)

Use default values for all modems.

Sample Network Profile *

(Acknowledged Communications)

All Modems: ATAM (auto-set MY (Source Address) parameter) **

ATDT FFFF (set Destination Address to 0xFFFF)

Basic Communication RF Modes

Streaming Mode (p42), Repeater Mode (p43)

Acknowledged Communication RF Mode

Acknowledged Mode (p46)

Point-to-Multipoint

Definition

RF data links between one base and multiple remotes.

Sample Network Profile *

(Basic Communications)

Base: ATMY 0 (set Source Address to 0x00)

ATDT FFFF (set Destination Address to 0xFFFF)

Remotes: ATAM (auto-set MY (Source Address) parameter) **

ATDT 0 (set Destination Address to 0x00)

Sample Network Profile *

(Acknowledged Communications)

Base: ATMY 0 (set Source Address to 0x00)

ATDT FFFF (set Destination Address to 0xFFFF)

ATRR 3 (set number of Retries to 3)

Remotes: ATAM (auto-set MY (Source Address) parameter) **

ATDT 0 (set Destination Address to 0x00)

ATRR 3 (set number of Retries to 3)

Basic Communication RF Modes

Streaming Mode (p42), Repeater Mode (p43)

Acknowledged Communication RF Modes

Acknowledged Mode (p46), Multi-Streaming Mode (p48)

Peer-to-Peer

Definition

Modems remain synchronized without use of a master/server. Each

modem shares the roles of master and slave. Digi’s peer-to-peer

architecture features fast synch times (35ms to synchronize

modems) and fast cold start times (50ms before transmission).

Sample Network Profile *

(Basic Communications)

Use default values for all modems.

Sample Network Profile *

(Acknowledged Communications)

All Modems: ATAM (auto-set MY (Source Address) parameter) **

ATDT FFFF (set Destination Address to 0xFFFF)

ATRR 3 (set number of Retries to 3)

Basic Communication RF Mode

Streaming Mode (p42)

Acknowledged Communication RF Mode

Acknowledged Mode (p46)

* Assume default values for parameters not listed. Profiles do not reflect addressing implementations.

** AM (Auto-set MY) Command must be issued through a terminal program such as the one incorporated in

the XCTU “Terminal” tab.
