Installation
3.15 Connecting the GXS dry pumping system for serial
communications
3.15.1 Serial port connection
GXS dry pumping systems have two 5-way XLR sockets that can be used to connect the pump for serial
communications. The user can connect by the PDT connector on the front of the pump, Figure 1 item 11 and by the
system interface on the rear of the pump, Figure 3 item 5.
An adaptor cable, Edwards part number D373-70-754, is available as an accessory. The cable is 2 m long with
a 5-way XLR plug on one end and a 9-way D connector socket on the other, allowing connection from the GXS dry
pumping system to a standard COM port on a computer. Should the user prefer to make their own adaptor cable,
refer to Table 9 for the pin-out of the XLR connectors.
Note: Some personal computers no longer come equipped with a standard 9 way D connector COM port. In this
case a USB to RS232 adaptor can be obtained.
For information about using SIM protocol with a serial port, refer to Appendix A2.13.
3.15.2 Ethernet connection
Connect the Ethernet cable to the pump by the Ethernet connection on the rear of the pump, refer to Figure 3 item 3.
Refer to Appendix A2.12 for information on how to set up and use the Ethernet port.
