Shimadzu LC-10/20 Pump

3 Installation Procedure

The Shimadzu LC- 10/20 Pump is controlled by serial (RS232)

communication. The communication is provided via the Optical to USB

convertor connected to the computer via USB A-A cable (p/n SK10) and to

the pump via optical cable (p/n SK15). Both of these cables are part of the

DataApex Opt-USB converter set (p/n OPT01), but can also be ordered

separately.

Optical to USB converter

For communication an OPT-RS232 converter is needed. It can either be

the DataApex Opt- USB converter (p/n OPT01) or Shimadzu adaptor

(Shimadzu p/n 22-35480-91).

Pump Settings

Communication parameters should be set on the pump in the SERVICE

MODE (see pump documentation) as follows:

Baud rate 2400, parity N, bits 8, stop bit 1.

SYS (Set System Parameter) has to be set to 5 for isocratic mode or to 6

for gradient mode from the pump keyboard.

Caution:

These values are not documented in the pump manual.
