TSL Test Bench

Generator and receiver for TSL UMD tally in one app — send from one window, watch it arrive in the other.

Overview

TSL Test Bench replaces TSL Tester. Where TSL Tester only listened, Test Bench also transmits: a TX window drives tallies, lamp colours and UMD text to a real device or router, and an RX window decodes whatever arrives on the wire. Run both side by side to check a tally chain end to end, or use either one on its own against a vision mixer, multiviewer or UMD panel. It supports TSL UMD V3.1, V4.0 and V5.0 over UDP and TCP, and every packet can be inspected as a hex dump with a decoded summary.

TSL Test Bench TX generator and RX receiver windows side by side
TX and RX side by side — tallies set in the generator show up on the receiver's UMD tiles
RX window UMD view showing dot-matrix display tiles with red, green and amber tally lamps
RX UMD view — rack-style dot-matrix tiles with tally lamps, here receiving V5.0 over TCP
TX window with display grid, lamp columns, V5.0 options and generators
TX generator — edit text and lamps per display, poll or send on change, and run the built-in generators
RX window table view with per-display tallies, checksum status, source address and packet log
RX table view — every field per display, V4.0 checksum status, source and age, plus the decoded packet log

Features

  • TSL UMD V3.1, V4.0 (checksum, lamp colours) and V5.0 (Unicode text, multiple displays per packet, DLE/STX framing)
  • UDP unicast, multicast and broadcast, TCP client and TCP server, in both directions
  • TX: click to toggle tallies and cycle lamp colours, edit UMD text inline, send on change or poll on an interval
  • TX generators: Clear, Random, Chase, Source Names, ASCII Sweep and Scroll
  • Frame preview showing the exact bytes for the display you're editing
  • RX: auto-detects the protocol per packet, and re-synchronises TCP streams
  • RX table view or UMD view with dot-matrix tiles, including legacy dual 8 + 8 displays
  • HDR UMD text and tally lamps on displays that support it, falling back to SDR automatically
  • Stats for packet rate, per-protocol counts, V4.0 checksum pass rate and errors, with stale displays dimmed
  • Packet log with hex dump and decoded summary for every packet sent or received
  • Small native app, about 3 MB to download, with a built-in update check
