Resetting Manifold Controller
This procedure clears the manifold controller's memory and restarts its microprocessor. All
programmed instructions such as the sample sequence will be erased.
Reset the manifold controller memory to the default (original factory) settings by pressing and
holding the “Program” key while you turn power switch to on.
Scan Table Downloading Format
The scan table contains the information for setting the sampling sequence of the manifold. Up to
100 steps can be contained in the table that is transferred from a computer through the RS232 port to
the manifold controller. A null modem nine-pin computer cable is required to connect the two units.
Using "ProComm" or "Windows Terminal" and communications set at 1200 baud, 8 data bits, 1 stop
bit, and no parity, send the following string to the manifold controller:
scan_XX_XX_XXCR
where: (scan) =
command; must be lower case
(_)
=
space (20 hex)
(XX)
=
port
number
(CR) =
carriage return (0D hex)
Changing "Home" Test Frequency
A "home" test is built into the manifold controller that automatically checks the manifold's station
readout with the mechanical port the manifold is actually on. Misalignment may be caused by
power failure, excessive vibration, or loose cable connections. The problem is normally corrected
by pressing the counter's ON key or by resetting the counter. Refer to particle counter's Operating
Guide for resetting procedure.
Switches internal to the manifold controller can be set to change how often the "home" test is
performed. The factory setting is for a "home" test after every eight port changes. Below are all the
combinations presently available:
