  • Page 3: Scope Of Manual

    1.2 GENERAL DESCRIPTION Integra-H is a high-speed protocol transparent radiomodem. It is designed specifically to fit the needs of Supervisory Control and Data Acquisition (SCADA), telemetry and control applications. Integra-H provides the communication links to data equipment for installations where wired communication is impractical.

    1-800-992-774. For international sales, phone 1-612-882-5529 or 1-305-829-4030. 1.2.3 CONFIGURATION Operating characteristics of the Integra-H are configured by means of Integra-H Radio Service Software (INTRSS). The RSS/RDS software kit also includes the Radio Diagnostic Software (INTDIAG), which permits both local and remote diagnostics. These programs are Win/95 or later based (16 Megabytes of memory required).

    1.9 FIRMWARE UPGRADES The Integra-H firmware resides in flash EPROM and is designed to allow field upgrades. Upgrades are done using a PC connected to the Integra-H but do not require opening the unit. Upgrades require interaction with DRL’s Technical Service.

    Integra-H output must be reduced by 4 dB (plus 1 dB to account for cable loss) 30 dBm - 4 dB + 1 dB (cable loss) = 27 dBm at antenna port of Integra-H after 1 dB loss through cable: 27 dBm - 1 dB = 26 dBm input to antenna...

  • Page 8: Network Application

    PRODUCT OVERVIEW 1.11 NETWORK APPLICATION Integra-H is suited to a variety of network applications. Its primary design goal satisfies the needs of SCADA systems using RTUs, PLCs, or other similar equipment in either point-to-point or point-to-multipoint service. This section gives an overview of some common configurations. Selection of “master” or “remote” as well as data delivery conditions is done using INTRSS.

  • Page 9: Common Characteristics

    Figure 1-4 Point-Multipoint System Using the Integra-H programming software, one Integra-H must be set to “master”. The remaining units in the network must be set to “remote”. All units are set to “selective” data delivery to prevent remote stations from hearing each other's responses.

    1.11.6 EXTENDING A LANDLINE (TAIL CIRCUIT) Integra-H may be used to extend a landline circuit (giving access to difficult locations, etc.). This type of connection is called a “tail circuit” and is shown in Figure 1-5. The tail circuit assembly may be used in any of the network types described in the preceding sections.

    (Safety Code 6 available from Health Canada). 2.2.2 RF EXPOSURE COMPLIANCE REQUIREMENTS The Integra-H is intended for use in the SCADA market. It must be mounted within a fixed RTU. The Integra-H must be professionally installed to ensure a minimum separation distance of more than 20 cm is maintained between the radiating structure and any person.

    * Contact technical support. 2.2.5 CONNECTION TO DTE Integra-H is configured as DCE. Most DTE should be connected using a nine-conductor pin-to- pin “straight” cable. Some RTUs or PLCs may require a special cable to route the signals correctly. See the documentation for your data equipment for further information.

    Figure 2-4 Integra-H rear panel 2.3.1 HEAT SINK The rear panel heat sink is essential for proper operation of the Integra-H transmitter. The unit must be mounted in a location that permits free air circulation past the heat sink. Cooling will be best if the fins are vertical.

  • Page 18: Power / Analog Connector

    FEATURES AND OPERATION 2.3.2 POWER The Integra-H power requires a regulated power source of 13.3 VDC nominal (10 - 16 VDC max.) negative ground with a minimum 2.0 A rating. An internal surface-mount 3A modem fuse (not field-replaceable) and a crowbar diode protect the main RF power components from reverse polarity.

  • Page 19: Operation

    The output signal supports the use of a redundant (HSB) base. 2.4 OPERATION Integra-H is designed for fully transparent operation. This means that all binary values are transmitted as data with minimum time delays and without regard to their binary value. “Break” signals can also be transmitted.

  • Page 20: Operating Modes

    RTS mode: The RTS signal is monitored for a low-to-high transition. This transition causes Integra-H to turn on its transmitter. CTS is raised 4 ms later to accommodate DTE that requires a CTS transition before it can send data. The transmission will continue until RTS is dropped or until the Tx Time out (see section 2.8) expires.

  • Page 21: Online Diagnostics

    On the receive side, Integra-H stations can be set to accept all data, or accept data only if it originates from a station of the opposite type (selective). This choice is made by setting Data Delivery to selective or all using the RSS.

    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.

Note that this is an approximate value that should be used for trend monitoring only. It does not compare in accuracy with values obtained by a standard wattmeter.

    FEATURES AND OPERATION 2.5.2.10 Reverse Power and SWR A reverse power reading above zero is an indication that the antenna, feedline or connectors are damaged, corroded or improperly tuned. This creates standing waves that are reported as a Standing Wave Ratio (SWR). Table 2-5 is based on a forward power of 1 watt (it may be scaled for lower power settings) and gives guidelines to interpreting these figures: Table 2-5 SWR / Rev Pwr Interpretation...

  • Page 28: Sleep Mode

    Check timer settings Polling protocols issue a poll and wait a certain time for a response. Integra-H adds a short amount of delay to each poll and response (typically in the order of 60 to 70 ms). Timer settings that are too short may cause erroneous indication of missed polls, in which case the application may retry or continue to cycle, ignoring the missed station.
  • Page 29 FEATURES AND OPERATION Use the highest suitable port baud rate (without exceeding the radio network speed) Operating an RTU at 1200 b/s on a 9600 b/s network will increase data transmission delays and reduce system performance. Evaluate the need for online diagnostics Enabling online diagnostics increases delays by 2.5 to 10 ms (depending on speed).

    This is particularly likely when field service is done during winter months. 1. Connect the Integra-H antenna connector to the radio service monitor RF input using a 023-3410-118 or equivalent 50-ohm cable. That input should be able to support at least 1 watt.
