Configured for ControlNet communication through an ISA/EISA host bus, the Allen-Bradley 1784-KTCX15/B (1784-KTCX15 ControlNet Interface Card) provides a host computer interface with dual BNC network connections and a specified 16 KB memory requirement.

Catalog and Hardware Identification

The supplied references identify 1784-KTCX15 as a ControlNet communication interface card for ISA/EISA bus systems. The alternate references are 1784KTCX15 and 1784-KTCX15/B. No additional suffix decoding is assigned because the supplied data does not define the meaning of "/B".

Electrical and Mechanical Specifications

ControlNet Host Interface Characteristics

The 1784-KTCX15 provides a ControlNet communication interface between the network and an ISA/EISA host computer bus. The card uses two BNC connectors for the specified ControlNet network connection.

The supplied data specifies a 57.6 kbps data rate, +5 VDC bus voltage with +/-5% tolerance, and 1.5 W typical power consumption. A 1500 VAC isolation voltage is also listed.

The supplied information does not establish PCI compatibility, Ethernet functionality, ControlNet network node capacity, firmware revision, or software driver version. These parameters should be verified from the applicable Allen-Bradley documentation before system integration.

ControlNet Electrical Interface

The specified 75 ohm termination requirement applies to the communication interface described in the supplied data. Incorrect termination can alter the electrical characteristics of the network segment and should be avoided.

The +5 VDC bus specification is stated as +/-5%. The 1.5 W typical power consumption corresponds to approximately 300 mA at nominal 5 VDC, but the supplied specification should remain the controlling value for installation calculations.

Installation and Connection Guidelines

Host Bus Installation

• Confirm that the host computer provides a compatible ISA or EISA expansion interface.
• Verify available bus resources before installing the card.
• Secure the card mechanically to prevent movement during BNC cable connection.

ControlNet Cabling

• Connect the BNC interfaces using the applicable ControlNet cable arrangement.
• Maintain the specified 75 ohm termination configuration.
• Keep network cabling separated from high-voltage switching conductors where practical.

Power and Grounding

• Verify the host bus provides the specified +5 VDC supply within the stated +/-5% tolerance.
• Maintain the host computer grounding arrangement during installation.
• Do not modify the card or its isolation structure to accommodate an incompatible power source.

Maintenance

• Record the existing card identification and host configuration before replacement.
• Verify the required 16 KB memory allocation and host bus configuration.
• Do not assume compatibility with later PCI-based host architectures.

Frequently Asked Questions

• What host bus does the 1784-KTCX15 use?

  The supplied specifications identify ISA/EISA as the host bus interface. PCI compatibility is not stated and should not be assumed.

• What network does this card interface with?

  It is identified as a ControlNet communication interface card. The supplied information specifies two BNC network connectors.

• What data rate is listed?

  The supplied technical data lists a 57.6 kbps data rate. No other communication speed is confirmed by the provided information.

• What voltage does the card require?

  The bus voltage is specified as +5 VDC with a +/-5% tolerance. The typical power consumption is listed as 1.5 W.

• What termination is required?

  The supplied specification requires 75 ohm resistors for termination. The exact termination location should follow the applicable ControlNet network design.

• What isolation rating is specified?

  The supplied data specifies an isolation voltage of 1500 VAC. The test method and duration are not provided.

• Can the card be hot swapped?

  Hot-swap capability is not specified. The host computer should be powered down before card removal or installation unless the complete system documentation explicitly permits otherwise.

• Is the operating temperature specified?

  No operating temperature range is provided. The storage or operating environmental limits should therefore be confirmed from the applicable Allen-Bradley documentation.
