SATO 200i manual Irda Specifications Ircomm Protocol, IRDA SPECIFICATIONS IrOBEX PROTOCOL

Unit 3: Interface Secifications

The IrCOMM protocol runs on top of IrDA and supports the emulation of a peer device similar to what’s connecting it by a serial or parallel cable for applications that access those ports through the operating system. Since various communication and printing applications utilize cables differently, cable emulation must account for those differences.

IrOBEX is a communictions protocol that facilitates the exchange of binary objects between devices and functions similar to HTTP in that a client uses a reliable transport to connect to a server to request or provide objects. The appropriate firmware must be installed for this to function.

This is a one-way communications protocol so therefore flow control and printer response are absent.
