The IO-EISO-5RS485 is a 5-port RS485 serial communication expansion module designed for use with CoreIPC mainboards. It converts TTL signals to five RS485 interfaces and provides RS485 RX/TX digital signal isolation.

Five 2 × 3 ピン JRS485 ヘッダー, with a 2.00 ミリメートルピッチ, provide the RS485 connections. Each header includes RS485_A+, RS485_B− and GND signals. The module includes one 2 × 5-pin COM2 header with a 2.54 ミリメートルピッチ, plus one 2 × 20-pin standard 4-port serial header with a 2.00 mm pitch for COM3 through COM6 TTL signal connections. Power is supplied through a 1 × 2-pin locking Phoenix terminal with 12V and GND pins.

The module measures 90 mm× 60 mm and includes four mounting holes for installation inside an enclosure.

Q: How many RS485 ports does the IO-EISO-5RS485 provide?

あ: The module converts TTL signals to five RS485 interfaces. Each RS485 port is provided through a separate 2 × 3-pin JRS485 header, allowing the module to present five RS485 connections.

Q: Does the module provide signal isolation?

あ: はい. The product documentation specifies digital isolation for the RS485 RX/TX signals. No isolation voltage or other isolation-performance value is provided in the current documentation.

Q: What power input does the IO-EISO-5RS485 require?

あ: The IO-EISO-5RS485 uses a 12V DC input through a 1 × 2-pin locking Phoenix terminal labeled 12V_IN. Pin 1 is GND, and Pin 2 is 12V.

Q: Which host-side serial interfaces are provided?

あ: The module provides one 2 × 5-pin COM2 header with a 2.54 ミリメートルピッチ, carrying RXD, TXD and GND. It also provides one 2 × 20-pin standard serial header for the COM3 through COM6 TTL signal connections.

Q: What are the module dimensions and mounting method?

あ: The IO-EISO-5RS485 measures 90 mm× 60 mm. Four mounting holes are provided, allowing the module to be secured inside an enclosure.
