J2 OPOS Simple Device Test 1.0

J2 OPOS Simple Device Test is a lightweight Windows utility from J2 Retail Systems designed to verify and exercise OPOS-compatible point‑of‑sale peripherals. It helps installers, integrators, and support teams confirm that OPOS service objects are correctly installed and that devices can open, claim, and operate as expected.

Key features:

• Discovers and connects to OPOS logical device names for common POS peripherals (e.g., receipt printers, cash drawers, barcode scanners, MSRs, customer/line displays).
• Performs core OPOS operations: Open, Claim, Enable/Disable, Release, and Close.
• Runs CheckHealth tests to quickly validate device readiness.
• Sends basic test commands such as printing a sample receipt or opening a cash drawer.
• Displays OPOS status, ResultCode, and ExtendedResultCode to aid troubleshooting.
• Captures events (e.g., data and status updates) to help diagnose configuration or driver issues.
• Provides simple logging to document test steps and outcomes.

Typical uses:

• Verifying driver installation and device registration after setup.
• Isolating hardware vs. configuration faults during support calls.
• Confirming peripheral behavior before deploying POS software updates.

Requirements and notes:

• Windows environment with the relevant OPOS service objects installed for each device.
• Intended as a diagnostic and validation tool; not a replacement for production POS applications.
