• Radio interference checks

For more information on how to perform these optimization

steps, refer to the MDS TransNET Reference Manual

(05-2708A01).

There are no manual adjustments on the radio. Programming and

control is performed through a PC connected to the radio’s DIAG

connector. Programming is performed by either establishing a

terminal connection to the radio (by using a terminal emulator such

as HyperTerminal), or by connecting to the radio using MDS

TransNET Configuration Software (P/N 06-4059A01). For more

information, refer to the MDS TransNET Reference Manual

(05-2708A01).

3.1 User Commands

The following tables provide brief descriptions of the various user

commands for the transceiver. For more information, refer to the

MDS TransNET Reference Manual (05-2708A01).

Table 1: Network Configuration—Master Station

Table 2: Network-Wide Diagnostics

3.0 RADIO PROGRAMMING

COMMAND DESCRIPTION

AT [ON, OFF] Enables Master station to emulate a

modem and respond to AT commands

BUFF [ON, OFF] ON = Seamless data

OFF = Fast byte throughput.

FEC [ON, OFF] Sets/disables FEC

(Forward Error Correction) setting.

HOPTIME [7, 28] Displays hop-time or sets it to 7 or

28 ms.

LPM [1, 0] Used at Master to set all associated sta-

tions in an energy-conservation mode.

1 = Low-power mode enabled net-

work-wide

0 = Disable low-power mode (Default)

REPEAT Sets/displays the fixed downstream

re-send count.

RETRY [0–10] Sets/displays the maximum upstream

re-send count for ARQ (Automatic

Repeat Request) operation

SAF [ON, OFF] Enables/disables the store-and-forward

function for the network controlled by

this Master unit.

SKIP [NONE, 1...8] Skip one or more frequency zones

COMMAND DESCRIPTION

DLINK [xxxxx/ON/OFF] Controls operation of diagnostic link

function.

DTYPE [NODE/ROOT] Set radio’s operational characteristics

for network-wide diagnostics

Table 3: Operational Configuration

COMMAND DESCRIPTION

ADDR [1–65000] Program network address

AMASK [0000

0000–FFFF FFFF]

Alarm response

Default: FFFF FFFF

ASENSE [HI/LO] Sense of the alarm output on Pin 6 of the

DATA interface connector in the EIA-232

mode. Default: Alarm present = HI

BAND [A, B, C] Selects one of three operating bands.

(2.4 GHz Model Only)

BAUD [xxxxx abc] Data communication parameters

CODE [NONE, 1...255] Select the security/encryption setting in

the radio

CSADDR [1–65000] Used on a single Master/Remote net-

work to support TDD-style simulated

full-duplex.

CTS [0–255] CTS delay in milliseconds

(A value of 0 returns CTS immediately)

CTSHOLD [0–60000] “Hold time” that CTS is present following

last character from DATA port.

DEVICE [DCE, CTS

KEY]

Device behavior:

DCE (normal) or CTS Key

MODE [M, R, X] Operating mode:

M = Master, R = Remote, X = Extension

MRSSI [NONE,

-40...-90]

Minimum RSSI level required to preserve

synchronization with a Master radio for

Remotes in mobile service.

OT [ON, OFF] Enables a 1-second delay on delivery of

RXD serial data.

OWN [xxxxx] Owner’s name, or alternate message

(30 characters maximum)

PORT [RS232, RS485] Data port (DATA connector) interface

signaling mode: RS232 or RS485

PWR [20–30] Power output in dBm

RXD [0–255] Set RXD delay time for virtual seamless

mode with low latency

RXTOT [NONE, 0–1440] Maximum duration (in minutes) before

time-out alarm. Default is OFF.

RTU [ON, OFF, 0–80] Enable or Disable unit’s built-in RTU

simulator. Default is OFF. Set RTU

address between zero and 80.

SLEEP [ON, OFF] Enable or Disable the radio’s

energy-conservation Sleep mode func-

tion.

UNIT [10000–60000] Unit address used for network-wide

diagnostics. (Unique within associated

network.)

XADDR [0–31] This unit’s Extended address

Typically, the Master is set to zero (0).

XMAP

[00000000–FFFFFFFF]

Included Extended units in MODE X.

(Extensions and Remotes only)

XPRI [0–31] Address of the primary Extended radio

unit (Extension).
