Communication Port
"uart1:"
All EasyCoder 201 II printers are fitted with a DB25 male interface
connector on their rear plates (comm. port "uart1:"). This connector
can be used for an RS 232C (standard), or a 20 mA current loop
interface depending on how the CPU board is strapped. In the latter
case, two optional opto-couplers must be fitted. The configuration
of the connection cable is also important.
If the printer is ordered without any connection cable, a suitable
cable can be procured locally and, if necessary, be modified
according to the pinout descriptions in this chapter.
NOTE!
A shielded communication cable is required in order to comply
with the FCC/DOC approval and to avoid
the risk of interference to radio communications.
