APPENDIX D. RS-232 AUXILIARY PORT
In addition to the RS-232 Host port, the MICR Plus offers the added benefit of an RS-232
auxiliary port. This port allows the user to attach an additional RS-232 device to the Host
through the MICR Plus. For example, Figure D-1 shows Mag-Tek’s IntelliPIN device attached
the RS-232 auxiliary port.

In this setup, the MICR Plus serves as a communication bridge between the Host and the RS-232
device, directing the data flow between the Host and the RS-232 device. It should be noted that

port.
