Serial I/O Cable Installation; Optically Isolated Inputs; Optically Isolated Outputs - Cardinal 210 Installation And Technical Manual

Serial I/O Cable Installation

The 210/215 indicators may be connected to a printer to record weight and associated data or
it may be connected to a remote display or even to a computer for transmission of weight data.
The weight data may be transmitted on demand (pressing the PRINT key or on receipt of a
command from the computer). Refer to the Setup, SIO Serial I/O section of this manual.
1. Remove the 12 acorn nuts securing the back panel to main housing, then loosen a gland
connector for the serial cable. Refer to Figure No. 2 for illustration of connector layout.
2. Slip the serial cable through the gland connector and into the enclosure.
3. Remove 2" of the outer insulation jacket then remove 1/4" of insulation from each of the
wires (refer to Figure No. 4).
4. Connect each of the wires to the Serial Data terminal block (P11) referring to Figure No. 8
for terminal block locations.
5. To terminate, first press down on the release bar for the terminal, insert the wire into the
opening then allow the release bar to return to its original position, locking the wire in place.
Repeat the procedure until all of the wires are in place.

Optically Isolated Inputs

Included with the I/O are 4 programmable inputs that may be used to remotely (up to 100 feet)
initiate various functions within the indicator. These inputs are accessed via a terminal block
(P9) on the back of the PC board (see Figure No. 8). The 4 inputs are defined as follows:
TERMINAL NO.
NOTE! The input must be connected to Gnd to initiate the function.

Optically Isolated Outputs

Preset Weight Comparator Checkweigher Logic Level Output
If desired, you may use the optically isolated outputs from your Model 210/215 indicator's
preset weight comparators or checkweigher to remotely (up to 100 feet) control peripheral
devices used to manage the flow of material or signal when the weight is within preset limits.
J11 (12V) - ACTIVE REMOTE OUT JUMPER
The Active Remote Out jumper J11, when connected, allows the 210/215 indicator to supply
(source) 12 VDC to a solid-state relay or other load of 200 ohms or greater. To operate from
the 12 VDC source, the positive connection from the relays must be connected to the PWC
connector pins and the negative wire from the relays to the GND pin. See Figure No. 8 for
jumper and REMOTE OUTPUT connector location.
