FEATURES AND OPERATION
2-9
Part No. 001-4090-101/102
Where user applications require continuous data transmission from a master unit, diagnostics are
delivered locally to its own setup port regardless of the
Online Diagnostics
setting at the start of each
data transmission and also at intervals of 20 seconds. If user-enabled, diagnostics are also sent on the
network but only at the start of the first data transmission.
Reception of online diagnostics is always enabled and is delivered out at the Setup Port in an
ASCII form.
Online diagnostics do not interfere with normal network operation. The following information is
gathered:
l
Unit's “short ID”
l
Inside case temperature: in degrees C
l
Supply voltage (B+): in volts
l
Local received signal strength: in dBm
l
Remote received signal strength: in dBm
l
Forward power: in watts
l
Reverse power: good / poor
l
Receive quality: based on last 15 data blocks received.
2.5.1 USING AN EXTERNAL PROGRAM FOR ONLINE DIAGNOSTICS
The Setup port communicates with the RDS using a proprietary protocol. However, if a terminal,
or PC running terminal software is connected to the Setup port, online diagnostic information will be
delivered in plain ASCII form. We will refer to the proprietary data format as RSS/RDS mode.
2.5.1.1 Initialization
When powered on, it will attempt to establish a link with the RSS/RDS and select its output
mode as follows:
1. If RTS is not exerted on the setup port, Integra-H will immediately switch to ASCII mode.
2. If RTS is exerted on the setup port, Integra-H will send an initialization message in RSS/RDS mode
and wait for the proper response form the RSS or RDS.
3. If there is no response, Integra-H will switch to ASCII mode.
A user-program should initialize the PC serial port with RTS false. This disables RSS/RDS
mode and only ASCII data will be output from the port.
2.5.1.2 Online Diagnostic String Format
In ASCII output mode, the setup port will output a one line diagnostic string each time the
unit receives a transmission from another unit. No other data will be output. The string
consists of a number of comma-delimited fields terminated by a carriage return. Each field
