Serial Communication and Data Handling Features
The GE IS200ESYSH1A IS200ESYSH1AAA High Speed Serial Board supports multiple industrial protocols for device connectivity. Each channel includes a large FIFO buffer to prevent data overruns. The board handles CRC generation and checking without CPU intervention. Furthermore, it provides hardware flow control for RS-232 connections. Consequently, your system communicates reliably with PLCs, HMIs, and remote I/O devices.
Installation and Connection Steps
Mount this GE IS200ESYSH1A IS200ESYSH1AAA High Speed Serial Board in any Mark VI rack slot. First, connect serial cables to the two DB9 ports securely. After that, set the port configuration using the onboard DIP switches. Then, attach the 50-pin header to the VME backplane adapter. Finally, verify each port’s activity LEDs flash during data transmission.
Energy Discharge and Safety Notice
This GE IS200ESYSH1A IS200ESYSH1AAA High Speed Serial Board stores minimal energy in its capacitors. However, you must wait 30 seconds after power removal before handling. The two decoupling capacitors discharge through internal resistors. Never connect or disconnect serial cables while the board remains powered.
Status Indication and Diagnostics
Two green LEDs indicate valid power and initialization for each port. Two yellow LEDs flash during active data transmission on each channel. A red LED illuminates when any port detects a parity or framing error. These indicators help technicians troubleshoot communication issues without protocol analyzers.
