In the context of barcode scanning technology (specifically Zebra/Motorola/Symbol ecosystems), **CBA-R** usually refers to a specific series of **RS-232 (Serial) Cables**. These cables are used to connect a handheld scanner to a host computer, POS system, or industrial controller via a DB9 port. --- ### 1. Key Components of a CBA-R Cable The "R" in the name typically signifies **RS-232**. These cables are more electronically complex than standard USB cables because RS-232 ports often do not provide enough power to run the scanner. | Part Category | Description | | :--- | :--- | | **Connector A** | Proprietary 10-pin modular plug (RJ-45 style) that plugs into the scanner handle. | | **Connector B** | DB9 Female connector for the host PC/Device. | | **Power Port** | A DC barrel jack located near the DB9 connector to accept an external power supply. | | **Circuitry** | Level-shifting components to match the voltage of the scanner to the RS-232 standard (+/- 12V). | --- ### 2. Common Variations The suffix after "CBA-R" defines the physical characteristics and specific electronic wiring: | Part Number | Description | Electronic Feature | | :--- | :--- | :--- | | **CBA-R01-S07PAR** | Standard RS-232 (DB9) | 7ft, straight cable, requires external power. | | **CBA-R02-C09PAR** | Coiled RS-232 | 9ft, coiled for mobility, requires power supply. | | **CBA-R21-S07ZAR** | TTL RS-232 | Uses Transistor-Transistor Logic levels for specific POS terminals. | --- ### 3. Electronic Requirements To make a CBA-R cable function correctly, two electronic conditions must be met: 1. **External Power Supply (PWRS-14000-253R):** Because RS-232 cannot deliver the 5VDC required by most scanners, an external AC/DC adapter must be plugged into the cable's barrel jack. 2. **Host Communication Protocol:** The host must be configured for the correct Baud Rate, Data Bits, and Parity to match the scanner's internal firmware settings. --- ### 4. Pinout Logic (Simplified) The DB9 side of the CBA-R cable follows the standard RS-232 pinout: * **Pin 2:** TX (Transmit Data) * **Pin 3:** RX (Receive Data) * **Pin 5:** GND (Ground) * **Pin 7/8:** CTS/RTS (Hardware Flow Control)
