This OEM-spec A00456 three-branch GPS-PDL composite cable solves RTK base station wiring failure pain points for field survey: separate data wire + power wire messy layout, single-function cables requiring multiple spare harnesses, inferior unshielded wire suffering construction site EMI interference, mismatched pinout causing differential data loss and radio power supply interruption, loose Lemo connector leading to frequent RTK fixed solution dropout, and short cable length limiting field base station layout adjustment. Triple-head integrated design: 10pin Lemo for Sokkia GRX GNSS host, 5pin Lemo for PDL radio, DC power jack for external power input, simultaneously realize RTK differential data transmission, radio constant power supply and radio parameter debugging, widely applied to highway control network, tunnel deformation monitoring, open-pit mine RTK base station and large-area cadastral measurement projects.

Product Overview

The Sokkia A00456 dedicated GPS-PDL multi-function composite cable is a full integrated wiring harness exclusively matched with Sokkia GRX series GNSS RTK and Pacific Crest PDL HPB high-power survey radio. Complete triple-head Y-type integrated structure: 10-pin 1B Lemo male plug (connect GRX1/GRX2 GNSS main unit data/power port), 5-pin 1B Lemo male plug (plug into PDL HPB radio communication interface), round DC power jack (access external 12V power adapter to supply radio continuous operating current). The whole cable adopts double-layer braided copper full shielded twisted pair wire core, thick wear-resistant matte gray PVC outer sheath, standard fixed 2m length, all three connectors adopt thick gold-plated pins to resist oxidation, damp tunnel slurry and construction mud long-term corrosion. Built-in independent signal separation isolation circuit inside the cable body, realize independent transmission of GNSS differential correction data, radio control signal and power current without mutual crosstalk. Standard RS232 serial communication protocol fully compatible with Pacific Crest PDL Windows configuration software, support one-click modification of radio working frequency, transmit power, baud rate and firmware upgrade maintenance operation. Direct plug-and-play without extra adapter conversion, greatly simplify field base station wiring layout and reduce the quantity of spare cables carried outdoors.

Core Advantages & Practical Structural Design

• 100% OEM standard pin definition, Y-type three-head layout, 2m wire length and double shielding structure consistent with factory original A00456 cable, one-piece replacement for broken, poor contact or unshielded split separate wires
• Three-in-one multi-functional integration: RTK differential data transmission, PDL radio external power supply, radio parameter programming/firmware upgrade three functions realized by single cable, eliminate trouble of carrying separate data line and power line during field mobile measurement
• Double-layer braided copper full shielding wire core, effectively suppress electromagnetic interference from construction machinery, high-voltage lines and radio equipment, avoid radio parameter reading failure and differential signal loss during long-distance measurement
• All connector terminals adopt thick gold-plated process, anti-rust and anti-oxidation, maintain stable signal and power conduction under high humidity, muddy mine and underground tunnel long-term working conditions
• Internal independent separated isolation circuit design, no data signal crosstalk between GNSS host, PDL radio and external power port, ensure stable radio parameter writing and continuous RTK differential broadcast output
• 2m reasonable standard length, meet most field base station placement distance requirements; thick wear-resistant outer PVC sheath, anti-tensile and anti-scratch, adapt to mountain rough terrain frequent moving and storage
• Exclusive cross-device compatibility: perfectly match Sokkia GRX1/GRX2 full series GNSS RTK receivers, Pacific Crest PDL HPB 35W high-power survey radio, coordinate with external 12V DC power supply and full set PDL whip antenna kits
• Compatible matching accessory: Trimble TSC3 / TSC2 Yellow Nylon Carrying Case ($25, 0.2kg, 18 × 12 × 10 cm)
• Flexible round integrated Y-shaped cable, can be freely coiled and stored, occupy small space in instrument maintenance tool pouch alongside iM52/iM55 silicone keyboards, RTK carbon fiber sharp points and survey mechanical spare parts

RTK Base Station Radio Debugging & Field Survey Application Scenarios

Necessary multi-functional wiring maintenance spare part for rural large-area cadastral mapping, municipal highway control network layout, urban tunnel long-term deformation monitoring, open-pit mine high-precision topographic survey and bridge static observation Sokkia GRX GNSS RTK base station projects. When the original split data/power cables are damaged or messy wiring causes PDL radio parameter modification failure and intermittent differential signal interruption, survey technicians directly use this integrated A00456 Y-type cable to connect GRX GNSS host, PDL radio and external power supply at one time, quickly enter PDL configuration software to adjust radio frequency matching rover station signal, upgrade radio firmware and troubleshoot differential transmission faults. Full double shielding wire core completely solve field electromagnetic interference leading to radio disconnection and parameter writing error faults; three-in-one integrated design greatly reduce the number of cables carried during outdoor mobile measurement, improve field equipment setup and debugging efficiency. Store this A00456 GPS-PDL composite cable and other tiny survey maintenance peripherals in our high-visibility yellow nylon data collector case; reinforced canvas belt loop supports waist hanging for convenient cross-region field instrument repair transport.
