Metrologic Scanner PS/2 & RS232 to USB Cables

USB conversion cables for selected Metrologic barcode scanners

This collection currently contains one 2m replacement cable listing with two selectable formats: RS232-to-USB and PS/2 keyboard-wedge-to-USB. It is intended for selected Metrologic barcode scanners explicitly named on the product page, including MS7120, MS1690 and MS9540.

This is not a general Honeywell Metrologic accessory range. The collection does not currently contain scanner cradles, stands, batteries, power supplies, holsters, scan windows, PS/2-only cables, standard USB replacement cables or Stratos in-counter scanner parts.

Available cable options

• RS232-to-USB cable: a 2m cable option intended to replace the stated older RS232 connection for listed scanner models.
• PS/2-to-USB cable: a 2m cable option intended to replace the stated PS/2 keyboard-wedge connection for listed scanner models.

The two variants serve different starting interfaces. Select the option that matches the existing scanner cable and configuration; do not choose by USB host plug alone.

How to choose the correct cable

1. Confirm the exact scanner model: read the full model code from the scanner label. Brand or series name alone is not enough.
2. Identify the old interface: determine whether the cable being replaced is RS232 or PS/2 keyboard wedge.
3. Check the scanner-side connector: the product describes an RJ48-style scanner connector, but a similar-looking modular plug does not prove pinout compatibility.
4. Review scanner configuration: changing the host interface can require scanner programming. Follow the scanner manual for USB host mode and barcode-based setup procedures.
5. Check software requirements: USB presentation to the host may depend on the cable electronics and scanner configuration. Do not assume that every RS232 device can be converted by a passive rewiring cable.

Compatibility boundaries

The current product states compatibility with Metrologic MS7120, MS1690 and MS9540. That model list should not be extended to every Orbit, Voyager, Focus, Stratos or Honeywell-branded scanner. Connector shape, contact assignment, interface electronics, power requirements and firmware settings can differ between models and revisions.

The product is described as manufactured by E-Simpo and not by Honeywell. It is sold by Yoeruyo as a third-party replacement cable. Metrologic and Honeywell names identify the intended equipment; they do not indicate an original Honeywell part or verified equivalence to every manufacturer cable number.

Physical details stated for this listing

• Nominal cable length: 2m
• Selectable interfaces: RS232-to-USB or PS/2-to-USB
• Scanner-side connector described by the source listing as RJ48
• Shielded cable construction described with internal copper conductors

These construction details apply to the current listing only. They are not universal specifications for all Metrologic scanner cables.

Frequently asked questions

Is this a standard USB replacement cable?

No. The available variants are specifically described as replacing an older RS232 or PS/2 connection with USB. A standard USB-to-scanner cable is not currently included in this collection.

Can I use it with any Honeywell or Metrologic scanner?

No. Use it only when the exact product page lists the scanner model and the existing interface matches the selected variant.

Are the RS232-to-USB and PS/2-to-USB variants interchangeable?

No. They start from different scanner interface arrangements and may require different scanner settings.

Will the scanner work immediately after changing cables?

Not necessarily. The scanner may need to be programmed for the USB host interface using its model-specific manual.

Is this an original Honeywell cable?

No. The product states that it is made by E-Simpo and is not a Honeywell-manufactured part.
