Wiring The Digital Inputs And Outputs; Time And Date Setting - Rice Lake IQ plus 800 Installation & Operation Manual

To provide the most clean and noise-free
5VDC power supply to terminal J4, pin 10
for digital outputs, use an external power
supply, such as RLWS # 16418. This is
especially important when digital outputs
are heavily utilized.
This only applies to units manufactured
before September 1, 1966. CPU boards
manufactured after that date automati-
cally provide clean 5 VDC power to J4,
pin 10 through the board circuitry.

WIRING THE DIGITAL INPUTS AND OUTPUTS

The standard unit allows 3 digital inputs and 4 digital outputs. Wire any
active digital inputs and outputs to connector J4 on the CPU board. See
Table 2-6 for J4 digital I/O connections.
Typically, digital outputs control relays which operate other equipment.
Each output is a normally-open collector circuit, capable of sinking 250
mA when "on" and withstanding +40 VDC when "off." All logic levels
are active (on) when a low voltage signal (-5 VDC) is present. The output
circuits also include 5V pull-up resistors to send a 5V TTL or 5V CMOS
logic signal when the outputs are closed (on). Use the SETPNTS menu to
configure the digital outputs.
You can wire as many as three external switches to the digital inputs.
These inputs can be set to duplicate keyboard functions. When used with
our #19369 Batching Start/Stop Switch, the inputs can be set up to start,
run, pause, and stop batch sequences. As with the outputs, the inputs are
active (on) with low voltage (-5 VDC) and can be driven by TTL or 5V
logic without additional hardware. Use the DIG IN menu to configure the
digital inputs.

TIME AND DATE SETTING

To set the time and date on the indicator:
Press TIME/DATE key once to display date. Press again to display time.
You can enter new values for the date and time while they appear in the
display. Simply key in a new value and press ENTER. Use the 24-hour format
to enter time values.
The display and printing format for both time and date can be altered in the
configuration mode under the Format menu.
NOTE:
Indicators manufactured prior to
September 1, 1996 do not provide
a 5 VDC power supply at J4, pin
10. Two methods may be used to
provide 5 VDC power to this pin:
• Solder an insulated red jumper
wire from J1, pin 4 to J4, pin 10.
• Use an external power supply to
energize J4, pin 10. Part # 16418
is recommended for this use.
Indicators made after that date
have 5 VDC built into J4, pin 10.
