IQ plus ® 510/710 Digital Weight IndicatorsInterface BoardPN 45312IQ plus 510 and 710 indicators using the Revision 1indicator CPU board are equipped with an interfaceboard to consolidate cable connections to externaldevices. The interface board (see Figure 1) provides aconnection point for load cells, digital I/O, and serialcommunications, and routes these signals to and fromthe CPU board, shown in Figure 2 on page 2.CautionUse a wrist strap to ground yourself andprotect components from electrostaticdischarge (ESD) when working insidethe indicator enclosure.Connectors J1—J5 each plug into a header on theinterface board. To attach cables, remove theconnector, insert wires, tighten the set screws, thenpress the connector back onto the header.Table 1 lists the load cell connections for connectorJ5; Table 2 on page 2 lists the serial communicationsand digital I/O connections for connectors J1—J4.See Section 2.0 of the IQ plus 510 or IQ plus 710Installation Manual for more information.45312DIGITAL INPUTBlack Cable to CPU Board J13DI1 DI2 DI3 DI4 DI5 DI6 DI7 DI8DIGITAL INPUTJ1SERIAL I/OCable to CPU Board J3RS-485+5V–I +I A B GND GND +5VRS-485SERIAL I/O - 2DO1 DO2 DO3 DO4 DO5 DO6 DO7 DO8DIGITAL OUTPUTJ2J3DIGITAL OUTPUTGray Cable to CPU Board J14(IQ plus 710 only)GND + 20mA – TxD RxDPRINTERSERIAL I/O - 1RxD TxDEDPGNDJ4–EXC +EXC SHLD –SEN +SEN –SIG +SIGLOAD CELLJ5Figure 1.
