Precautions

Installation location and necessity

Mandatory installation requirement: TB850, as a CEX Bus terminator, must be installed on the last unit of the CEX bus, which is the key to ensuring the integrity of the bus signal. If not installed according to this requirement, it may cause bus signal reflection, attenuation, or interference, leading to unstable communication, data transmission errors, and even system failures.

Location confirmation: Before installation, it is necessary to clarify the topology structure of the CEX bus, accurately identify the units at the end of the bus, ensure that the terminal is directly connected to the unit, and avoid being mistakenly installed at intermediate nodes.

Physical installation and connection

Connector matching: The product is equipped with a 25 pin DB25P male connector. During installation, it is necessary to confirm that the device interface connected to it is a matching DB25 female connector, and the pin definitions are consistent to prevent poor contact or signal misalignment caused by interface mismatch.

Fixed method: When using screws for fixation, it is necessary to use screws of appropriate specifications (recommended to refer to the product manual) to ensure a firm connection between the terminal and the equipment, avoiding loosening due to vibration, impact, and other factors that may affect signal transmission. Meanwhile, the fixing force should be moderate, as excessive tightening may damage the connector or equipment interface.

Space reservation: The net size of the product is 16mm in height and 50mm in width. Sufficient space should be reserved during installation to avoid squeezing with other equipment or cables, prevent connector deformation under stress, and facilitate subsequent inspection and maintenance.

Electrical and system compatibility

Voltage range: This product is suitable for circuits with a voltage not exceeding 1000 volts. When using it, it is necessary to ensure that the operating voltage of the CEX bus is within this range to avoid equipment damage caused by overvoltage.

System compatibility: Only compatible with AC 800M series (versions 4.1, 5.0, 5.1, 6.0) and 800xA system (including 800xA 6.0 system and AC 800M related software and hardware versions). Before use, it is necessary to confirm whether the control system version is in the compatibility list to prevent functional failure due to system mismatch.
