Register map(s) for this device, each at the trust rung it earned. Addresses are 0-based as on the wire. Word order and scaling are confirmed at the hardware-verified rung and at no rung below it.
Read + decoded cleanly over a real network vs an independent third-party Modbus test server (transport and framing; reads are remapped into the server's register window, so the map's own addresses are NOT exercised). Does NOT prove word order/scaling against the actual device.

⚠ Turn the power supply to the instrument off before wiring or checking it. Working on or touching the terminal with the power switched on may result in severe injury or death due to electric shock. — Starkest reads only; we never write a control register.
| terminals | 13 YA(-), 14 YB(+), 15 SG |
| A/B polarity | YA(-), YB(+) |
| termination | Do not connect the terminator to the communication line because each JCx-33A has built-in pull-up and pull-down resistors instead of a terminator. |
| shield/ground | Connect only one end of the shielded wire to the FG terminal so that current cannot flow to the shielded wire. |
| wiring notes | Recommended cable: OTSC-VB 2PX0.5SQ or equivalent (twisted pair cable). |
| max registers/read | 1 |
| inter-frame delay | 1000 ms |
| broadcast | supported |
| protocol notes | Up to 1,000,000 entries can be stored in memory. Frequent transmission is not recommended. |
| doc revision | No.JC3CE11 2013.01 |
⚠ disputed: inter_frame_delay_ms: 1000 — disputed by Shinko JCS/JCM/JCR/JCD-33A (C5) manual No.JC3CE11, which specifies standard Modbus RTU timing (data interval of 3.5 characters or less)
Each rung states what it proved and what it did not. Gray until proven; green is earned by hardware only.
If your device isn't here, upload its register map. Generation is free, and the connector keeps the rung it earns under testing.
To prove a connector against your own device, order hardware verification. If it doesn't verify, you don't pay.
Platform builders can license the verified library: machine-readable maps, the firmware matrix, API access.
