Free utilities from our engineering team — rolling out one by one. Tools marked Available are ready to use.
WIMNET Modbus Scanner
Modbus master, device & register scanner with byte-swap decoding (ABCD / BADC / CDAB / DCBA) over TCP & RTU.
4–20 mA Loop Explorer
Drive a live current loop — set the tank level and the supply, feel the compliance limit, cut the wire, and see exactly how a 2-wire sensor wires to the gateway.
Open the tool — runs in your browserAvailableModbus Hex Converter
Paste hex from any meter or PLC — decode Int, UInt and Float in ABCD / BADC / CDAB / DCBA, verify CRC-16 and encode values back to register bytes.
Open the tool — runs in your browserAvailableCellular Bands by Country
The 3GPP LTE and 5G NR bands deployed by network operators in any country — per operator, with band numbers and MHz, plus legacy 2G/3G. Specify the right band variant for a 4G/5G gateway.
Open the tool — runs in your browserModbus Simulator
Multi-slave Modbus TCP / RTU simulator for bench testing, demos and integration trials.
Download — available soonJSON Packet Simulator
Compose and validate Wiman JSON payloads before wiring up your server integration.
Download — available soonAnimated, hands-on explainers of how Wiman gateways work — rolling out one by one. Guides marked Available are ready to explore.
How Gateway Data Moves
Watch a reading travel from gateway to server — POST + JSON vs GET + CSV, status codes, timeouts and store & forward, fully animated.
Open the guideAvailableGateway LED Patterns
Play every front-panel blink pattern live — PWR, GSM / CON, TXD, RXD — and diagnose network, Modbus and SIM faults in seconds.
Open the guideAvailableHow Store & Forward Works
What happens to readings when the link drops — buffering, flush order and batch limits.
Open the guideAvailableJIO 4G Switching
A new Jio SIM that never attaches in a 4G gateway but works instantly in a phone — the field procedure, what to rule out first, and why Jio behaves unlike any other Indian operator.
Open the guideAvailableHow Modbus RTU Works
Watch a master poll a meter, VFD and sensor live over RS-485, then learn the register types, function codes and bus rules.
Open the guideAvailableModbus RTU vs TCP
Same registers, different wire — frame anatomy side by side, one-master vs many-clients, and how to bridge the two without touching your devices.
Open the guideAvailableRS-485 Wiring Guide
Daisy-chain, terminate, bias, ground — why the differential pair beats noise, where the 120 Ω really goes, and the six classic dead-bus mistakes.
Open the guideAvailableRS-232 vs RS-422 vs RS-485
Three serial ports, three jobs — one wire vs the differential pair, who may talk on each, the 15 m vs 1200 m distance race, and where each belongs.
