Sierra Wireless DART 300 Using This Configuration

User’s Guide UDP/TCP Service

2110212 Rev 1.0 Page 77

Table 8-2: Sample Configuration – Meter (continued)

Command Remarks

[+WS62=0] Optionally disable local PAD echo. RxD is not connected so

this is not required. It may actually be desirable to keep PAD

echo enabled so that a terminal can be simultaneously connected

on-site to the modem’s RxD pin to monitor the data being sent

by the meter.

+WS72=0 Disable PAD editing. The binary data may include the <BS>

character as valid data.

+WS63=0 Disable the primary forwarding character. The binary stream

has no defined delimiters.

+WS70=2 PAD will forward a packet on 0.2 seconds idle from the meter.

This duration is equivalent to 48 characters at 2400 bps.

[+WS74=<n>] Optionally set a packet length limit below the default of 1000.

The inter-character timer is the only other forwarding condition.

&D0 Ignore DTR. The cable artificially asserts the signal.

S12=150 Set the TDES guard time to three seconds. The meter sends at

one-second intervals so it will not trigger an escape sequence.

Keeping TDES enabled with a safe guard time allows service

staff a means to connect a terminal, escape data state, and regain

command control of the modem.

+WS60=0 Disable TIES. The binary data stream may accidentally contain

this string.

&W Save the configuration.

+IPR2400 Set the modem to 2400 bps to match the meter. The modem

will reset after this command and is ready for field use.

Note: Setting Echo off (E0) and Quiet on (Q1) are not needed in this case, since the modem does

not have a receive (Rx) connection to the meter. These features are left at their default to allow

service personnel to connect a terminal and use the modem.

Using This Configuration

The configuration offered above assumes use of UDP and a fixed IP address and port for the

monitoring server. The DART 300 is placing the data on the network whenever the modem is

powered on and in CDPD coverage. The monitor needs only connect to the network and accept

the packets. There is no means to remotely control the session at the DART 300.

In the event of power disruption at the DART 300, it will automatically recover when it powers-up

or resets. The modem will open the UDP session, register, and send telemetry without any

intervention.
