Zebra CBA-R01-S07PBR Serial Cable DB-9
Overview
The Zebra CBA-R01-S07PBR is a 7-foot wired serial cable designed for direct connectivity between RS232-enabled peripherals and host systems in retail and warehouse environments. Built around a DB-9 female connector with TTL current limiting, this cable bridges legacy serial communication gaps where USB or network connectivity is unavailable or impractical—typical in fixed-mount barcode scanners, industrial label printers, payment terminals, and data collection devices that predate modern IP or wireless standards.
This is an accessory cable, not a standalone device. Its role is to carry deterministic, low-latency serial commands and data without the latency variability of Ethernet or the power overhead of powered USB hubs. If your scanner, printer, or POS terminal has a DB-9 serial port marked COM1, COM2, or similar, the CBA-R01-S07PBR (often searched as CBA R01 S07PBR) will likely fit—but always verify your device's port type and pinout before ordering.
Key Features
- 7-foot length: Reaches from a counter-mounted scanner or printer to a nearby POS terminal or server without requiring additional splitters or repeaters. At 7 feet, you're typically within the reliable RS232 distance window; longer runs (30+ feet) risk signal degradation unless you add a serial extender or active repeater.
- DB-9 female connector: Mates directly with standard DB-9 male ports found on legacy industrial and point-of-sale equipment. No gender adapters needed on the cable itself, though your host device may require a different connector type (check compatibility before purchase).
- RS232 communication standard: Supports traditional serial protocol used in barcode scanners, label printers, receipt printers, payment terminals, and weighing scales. RS232 is proven, deterministic, and requires no software drivers on most operating systems—it simply appears as a COM port.
- TTL current limiting: Built-in protection against voltage spikes and short circuits that can occur in industrial environments. This extends cable life and reduces the risk of damage to the host device's serial port, particularly valuable in warehouse settings with electromagnetic interference from machinery or radio frequency equipment.
- Straight connector design: Non-crossed pinout. The CBA-R01-S07PBR uses a 1-to-1 pin mapping. If your scanner or printer requires a null-modem cable (pins 2 and 3 swapped), this will not work—you'll need a null-modem variant instead.
- Suitable for retail and warehouse counter configurations: The 7-foot length and connector type are optimized for typical mounting—scanner on counter, terminal under desk or in a pole mount, printer nearby. Standard industrial environments (clean, temperature-controlled retail/warehouse floors) are the normal use case.
Integration & Compatibility
The CBA-R01-S07PBR connects any RS232 device with a DB-9 male port to a host system (PC, terminal, printer, or other equipment) with a matching DB-9 female port. Confirm your device's port label and pinout before ordering—some equipment uses DB-9 but with non-standard pin assignments (e.g., printers using RXD/TXD only, without handshaking). If your host system has only USB ports, you'll need a separate USB-to-serial adapter; this cable does not include one. For longer distances (20+ feet) or in electromagnetically noisy environments, consider adding a serial extender or shielded variant to maintain signal integrity.
Frequently Asked Questions
Q: Will the CBA-R01-S07PBR work with my specific barcode scanner or printer?
A: Only if your device has a DB-9 male serial port and uses standard RS232 pinout (TXD on pin 3, RXD on pin 2, GND on pin 5). Check your device's manual for port type. Some devices use DB-9 but with custom pinouts or null-modem configuration—verify pinout compatibility before purchase.
Q: Is this cable shielded?
A: The evidence provided does not specify shielding details. If EMI (electromagnetic interference) is a concern in your warehouse or retail floor, contact the manufacturer or your distributor to confirm shielding specifications before ordering.
Q: Can I extend the CBA-R01-S07PBR beyond 7 feet?
A: RS232 signals degrade over long distances. The 7-foot cable is within the RS232 reliable range. For distances beyond 20–30 feet, use a serial extender, active repeater, or fiber optic serial converter to maintain signal integrity and avoid data corruption.
Q: What's the difference between this cable and a null-modem cable?
A: The CBA-R01-S07PBR uses straight-through pinout (1-to-1). A null-modem cable swaps pins 2 and 3 to cross TX and RX signals. Use this cable only if your host and device both expect standard pinout; use null-modem if you're connecting two DTE devices (e.g., two terminals or a terminal-to-terminal link).
Q: What's included in the box?
A: The available evidence does not specify package contents beyond the cable itself. Contact the manufacturer or your distributor for details on whether ferrite clips, cable ties, or other accessories are included.
Q: Is there a warranty?
A: The manufacturer's warranty terms are not provided in the available evidence. Consult the product datasheet or manufacturer documentation for coverage details.

The Zebra CBA-R01-S07PBR is a straightforward serial cable that solves a specific problem: connecting legacy RS232 peripherals to a host system without fuss. At 7 feet with a DB-9 female connector and TTL current limiting, it's built for retail and warehouse counter layouts where a scanner or printer sits a few feet from a terminal or server. The cable itself is passive—no power draw, no configuration—which is exactly what you want when you're bridging older equipment that predates USB and Ethernet.
Technical Highlights:
- 7-foot length: Bridges typical counter-to-terminal distances without the latency or complexity of powered USB hubs or wireless. RS232 remains the standard for barcode scanners and industrial printers where deterministic, interrupt-driven communication is critical.
- DB-9 female connector with TTL current limiting: Direct mate to standard serial ports, with built-in protection against spikes and short circuits common in warehouse electrical environments. Reduces risk of port damage on expensive POS terminals or printer controllers.
- Straight pinout design: 1-to-1 mapping means this works only with devices expecting standard RS232 pinout. Verify before ordering—many industrial devices use custom pin assignments or null-modem logic.
Deployment Considerations:
- Confirm your target device has a DB-9 male serial port. Many newer terminals have eliminated serial ports entirely in favor of USB or Ethernet—if your host is USB-only, you'll need a separate USB-to-serial adapter.
- Watch for null-modem requirements. Some printer-to-terminal links swap TX/RX pins; the CBA-R01-S07PBR does not. If configuration fails on first connect, suspect pinout mismatch—a null-modem cable may be needed instead.
- Seven feet is safe for RS232. Beyond 30 feet, signal degradation becomes real, especially in environments with heavy electrical machinery (forklifts, conveyor motors, welding equipment). Plan longer runs with active repeaters or serial extenders.
Deploy the CBA-R01-S07PBR in stable, temperature-controlled retail and warehouse environments where legacy barcode scanners, label printers, and payment terminals connect to a nearby POS workstation or data collector. It's not a upgrade cable—it's the right cable when your equipment and your host both speak RS232 and both have the correct connector type. Verify compatibility first; this is not a universal solution.
