Dear Customer,

You’ve been identified as a purchaser of P/N 4289 (Enhanced Reconfigurable 32-Channel RS485/RS422 Differential I/O FPGA-Based PMC) or its derivatives (see derivatives table below) in the past. Due to the component shortages, Technobox, Inc. is no longer offering this product to our customers, and due to unexpected demand, we have nearly exhausted our supply of excess P/N 4289 inventory earlier than anticipated. As an alternative to the P/N 4289, Technobox, Inc. designed a “Tech Refresh” version that will address all the functions of its predecessor, under P/N 9136. 

Thank You,
Joseph Norris, President
Technobox, Inc.
