In case CyberScan pH 100 meter’s output has to be sent to a 25 pin RS232C connector, the
following cable configuration may be used:
CyberScan pH 100 25 pin connector
2 (TxD) (RxD) 3
4 (DSR) (DTR) 20
5 (GND) (GND) 7
7 (CTS) (RTS) 4
1. CyberScan pH 100 uses hardware handshake i.e. CyberScan pH 100 expects both DSR
and CTS lines to be active before it sends data.
2. If the [PRINT] key is pressed while the printer is not ready or if the printer is off, the
CyberScan pH 100 meter displays error message by showing both the printer and the
ERR annunciators blinking alternately, and awaits the printer to be ready (Figure 14).
3. While the meter is displaying printer error, you
may press CAL/MEAS key to return to the
measurement mode.
