3. SERIAL COMMUNICATION OF THE PUMP
3.1. General
The ARGUS 708 Volumetric pump has two serial interfaces on board. One is wired
to the docking interface connector and one is connected to the RS232 connector.
Important remark!
Only the RS232 connector is galvanic separated. The docking interface on the
pump is a non galvanic isolated interface! Do not use the docking interface on the
pump together with the interface cable (part 10.093) on a patient!
If the pump is intended to be monitored as a standalone pump on a patient, use the
RS232 connector (RJ45, beside the drop detector connector). To use it, configure
this connector as the default serial interface (refer index #55 in the configuration).
If the pump is docked into a docking station ARGUS 60 M or ARGUS 100 M, the
software switches automatically to the docking interface and the docking station
builds the separation device (galvanic isolation) then.
3.2. Serial communication protocol
The following characteristics are basics for all the ARGUS devices (volumetric
pumps, syringe pumps, docking stations with V4.xx and PCs) which are intended to
communicate with the device mentioned in this service manual.
• Full-duplex RS232, currently 4800Baud for single pumps,
9600 Baud for docking stations (also on master/slave-link).
• Simple master (host/PC) – slave (device) communication (host does polling).
• The host has to repeat the request if there is no valid response.
• Uses a checksum (CRC-8).
• Binary data transmission, thus no ASCII/text parsing.
• Fast & direct communication with pumps on ARGUS docking station.
• Specified timeouts during remote mode.
• Basic framing technique used as in the
Serial Infrared Link Access Protocol (Ir-
LAP) Version 1.1
.
Please contact your local distributor or ARGUS Medical AG for the complete serial
communication protocol description.
