SERIAL COMMUNICATIONS EXAMPLES

CONNECTING TO AN RLC PRINTER

The drawing shows the indicator with the 20 mA Serial Communication Option set-up with an RLC Model DMPC printer. An external current source is required to implement the printer’s busy signal to the indicator’s receive loop, which prevents overruns. The “Print switch” is a momentary contact, push button type connected between the E2-CON (TBA #8) and the signal common (TBA #7). The print function and E2-CON must be pro- grammed and the baud rate must match those of the printer. If a printer is used which does not have a ‘busy’ line, current must still be flowing into the indicator’s receive loop before transmission can occur.
