Shenzhen Zhiwei Electronics Technology TXHX13‑ZW20DX1 High‑Speed Carrier Communication Single‑Phase Module Specification
The TXHX13‑ZW20DX1 module is designed for smart‑grid electricity information collection systems, providing high‑performance, low‑power carrier communication for single‑phase smart meters. It interfaces with concentrator modules to deliver meter data, tariff updates, event reporting, and remote firmware upgrades.
Key technical features include OFDM signal modulation, four selectable working bands (0.7‑2.93 MHz, 2.441‑5.615 MHz, 1.758‑2.93 MHz, 1.953‑11.96 MHz), communication rates from 55 kbps to 10 Mbps, and a CSMA/CA access mechanism. The module operates from –40 °C to +70 °C, consumes ≤1.5 W dynamic and ≤0.4 W static power, and can communicate up to 200 m (500 m max) over power‑line channels. This manual is written in Chinese.

Zhiwei Electronics HPLC运维手持终端 Handheld Terminal User Manual
The guide starts with Bluetooth connection steps: enable Bluetooth in the terminal menu, launch the HPLC运维 APP, and pair with the device (OPHT‑XXX). Once connected, the APP displays device parameters and allows testing operations.
It then describes HPLC module testing, whole‑machine fault detection, and network testing (both to a physical concentrator and a virtual concentrator). Detailed functions include reading measurement points, retrieving and setting concentrator parameters, performing concurrent meter reading, and upgrading module firmware. This manual is written in Chinese.
