PRINTER WIRING
A “serial” printer may be connected to the TB1 connec-
tor on the Chiller Logic Board for the purposes of log-
ging data and troubleshooting. Weightronix Imp-2600,
Seiko DPU-414, and Okidata Microline 184 printers or
equivalents may be used.
Printer designs change rapidly. The user
should use the printer manual for the
respective printer for set-up and wiring.
Data from the chiller is transmitted at 1200 baud.
Wiring diagrams for cables are shown below:
