PointScan/440
Portable Remote I/O Field Configuration Tool
Operation
This setup tool is the most convenient way to configure a PointScan/200 module. Unplug any module and
insert this setup tool in its place. Commands from the IO Toolkit in your Windows-based PC store the
configuration information into permanent memory in the module’s base. This module automatically reads
the unique serial number stored in the base, making it unnecessary for you to enter the serial number into
the software manually. Upon reinsertion, the I/O module finds this configuration information, instantly
configures itself and begins to scan I/O. It is permissible to configure PointScan/200 modules in live
systems using this setup tool.
Note: PointScan/200 “smart bases” allow hot swap of live modules -- an exclusive IOtech feature.
Wiring
Connect this module to your Windows PC using a standard Serial (RS232) cable. Only the transmit (TD),
receive (RD) and common return (GND) signals are actively used. The RS232 port on this configuration
tool is electrically isolated to protect your computer in the event of field wiring errors. This module
requires DC supply power on terminals 17 and 18 on the wiring base it is plugged into. No other
connections are required. (I/O wiring will be left undisturbed.)
RS232 Mode
This module always communicates to the host PC at 9600 baud, with no parity and eight data bits. Be sure
to set the communications port on your computer to these default settings.
Alternative Setup Method
PointScan/200 modules may also be configured by connecting the RS485 party-line to an RS485 port or
RS232 port (through a converter) on your PC. It will be necessary to enter the serial number found on each
module’s base in the IO Toolkit to enable this setup software to initially talk to each module. In most
situations, setup through the RS485 port can only be done with the system off-line. Use a PointScan/440
module for on-line setup changes. (See above.)
IO Toolkit
All configuration parameters are entered using the IO Toolkit Windows software, which stores all setup
information into permanent memory in each module’s wiring base. No field jumpers or DIP switches are
required on PointScan/200 module (except wiring jumpers in the base of some 4 - 20 mA input modules).
