Technical Information
Procedure to Connect the Serial and I/O Ports to an External Cable
Ion Pump Control Unit - Operator /
Host Serial Communication
The Controller Report and Operator/Host Command are ASCII
strings CR (0D hexadecimal, 13 decimal) terminated.
Communication Parameters are 9600 bits/sec, no parity, 8 bits data,
1 stop bit.
Usually the human interface of the controller is a terminal emulator
(Windows "HyperTerminal" communication program for example)
running on Personal Computer. Software program on PC or PLC can
use the same ASCII protocol described below for human interface for
doing automatic control and monitoring of the controller. Every
500 msec, if the controller is in Report mode (default), all the 3
Report strings made of 30 characters each, corresponding to the 3 HV
channels are sent by the IPCU.
The string is always made of 30 characters for each HV channel
(independently by the channel status). A transmission from the
external PC, turns the IPCU to the Command Mode. To go back to the
Report Mode complete the command string with CR (0x0D) or ESC
(0x1B). Every single received character is Echoed back in order to
allow a control by the operator.
