Special Features

  • [ADAPTIVE DUAL MODE CONVERSION] This RS232 to RS485/422 adapter eliminates the need for manual jumper switching by automatically adapting to either RS485 or RS422 networks. Simply connect to the corresponding wiring mode and the device instantly converts single ended RS232 signals into balanced differential signals, ensuring seamless integration with attendance machines, access control systems, and industrial automation setups.
  • [ROBUST SURGE AND VOLTAGE PROTECTION] Equipped with an advanced voltage clamp protection circuit and anti surge capability, this passive interface converter reliably safeguards your connected equipment against sudden voltage spikes and electrostatic discharges. The design allows for a maximum differential pressure of ±5.7V between devices, providing long term durability even in demanding industrial environments.
  • [WIDE COMPATIBILITY AND CASCADING SUPPORT] Fully compliant with EIA/TIA RS232C, RS485, and RS422 standards, this adapter supports transmission rates from 300 to 115200 bps and distances up to 800 meters. It can cascade up to 16 to 32 devices on a single network, making it ideal for parking systems, automated banking systems, and bus toll collection networks.
  • [COMPACT AND PORTABLE DESIGN] Measuring just 55 x 35 x 15mm and weighing very little, this lightweight adapter is easy to carry and install in tight spaces. The DB9 female RS232 port and male RS485/422 port, combined with a six position terminal block, simplify wiring and allow for quick deployment in canteen sale systems and highway toll stations.
  • [EASY TO USE PLUG AND PLAY OPERATION] No complex configuration or external power supply is required for basic operation. Just connect the adapter to your attendance machine or IC card charging system using twisted pair cables, and it will immediately begin transmitting data. The passive design also minimizes heat generation, ensuring stable performance in temperatures from 0°C to 70°C.

Description

Spec:

Item Type: Adapter
Interface Features: The interface is compatible with EIA/TA RS232C and RS-485RS422 standards.
