Re: What cable i need for programing E28 HRP

The Hitachi "E" series, all but (1) model of the "EB" series (CRP), and the "EM" processors (CPM-E/CPM-E2) did not have a RS232 port. Connection to a laptop is accomplished through the use of a "serial protocol converter". This device, part number PGM-JR2, is actually a hand-held programmer. By setting a DIP switch, the COM port on the unit is activated. The PGM-JR2 is connected to the PLC via an attached ribbon cable. (Some models have provision for attaching the PGM-JR2 directly onto the face of the PLC.)

A cable is then connected to the PGM-JR2 on-board (DB25) serial connector, and to your (DB9) laptop COM port.

The cable is part number ActCab-PGMJ2. We can provide you the pin-out for this cable.
