Information on the Printer Option
Th Printer module is essentially a TCI comm 4 board with a daughter board installed to
communicate RS232 to the Printer. The Printer module is a listen only device and its software
revision level will not show up in service tests.
The diagnostic LED in the upper left hand side of the module is only active for the printer module,
and when it is on, this indicates a loss of communications with the Chiller module.
The Green LED labeled RXA should be continuously flashing.
The Red LED labeled TXA should never come on.
The Green LED labeled RXB will blink once every few seconds while the Printer module is
printing, only if X-ON X-OFF handshaking is enabled.
The Red LED labeled TXB will blink constantly while the printer is printing.
The DIP switch settings for the Printer module follow:
1-off
2-off
3-on
Dip switch settings for the Okidata Microline 184 turbo printer follow:
