Note: Requires cable8510-C304-GA. Available from our Parts Department at 1-800-641-2045 or by email at parts@cardet.com.The signal characteristics conform to the definitions of ANSI/EIA-232D.When the unit is ready to recognize received data on its RX line (pin 3), it will change the voltage on its DTE-Ready line (pin 20) from an 'OFF' to an 'ON'. When transmission is initiated by pressing the PRINT XMIT key onthe keypad, or by receipt of an ENQ character (05 hex) on the receive RX line, the unit will transmit data on its TXline (pin 2) only if it receives an 'ON' signal on its DCE-Ready line (pin 6).Signal levelsMark -3V to -12VDC (Logic 1)Space 3V to 12VDC (Logic 0)Signal identificationPIN 1 CHS Protective groundPIN 2 TX Transmitted data, from MSB-25PIN 3 RX Received data, to MSB-25PIN 6 DSR Data set ready, to MSB-25PIN 7 COM Signal groundPIN 20 DTR Data terminal ready, from MSB-25Data format1200 baud (standard), 1 start bit, 7 data bits, no parity, 2 stop bits on transmit, 1 stop bit on receiveRecord formats (depending upon current mode of MSB-25)WEIGHTSWWWWWW_lb_M_CC_SPP_lb_00.00_oz_M_CC_COUNTCOUNT_NNNNNN_PIECES PER POUNDPC/LB_NNNNNN_AVERAGE WEIGHT PER PIECEWT/PC_SPPPPPP_lb_WT/PC_SPP_lb_oo.oo_oz_S =P =W =O =M =CC =N = = =_=Space (positive) or - (negative)Pounds, Leading zero suppressed to space,embedded decimal point (if any)WEIGHT VALUE in decimal poundsOunces, decimal always present as shownModes: G = gross, N = net, T = tareMO = MotionCZ = Center of zero*OC = Over capacity*BZ = Below zero*(reflects state of gross weight only)Number for count or pieces per pound, decimalpoint (if any)Carriage return (OD hex)Linefeed (OA hex)space (20 hex)INTERCONNECTIONSDATA OUTPUT CONNECTION DIAGRAMPIN LOCATION AS VIEWED FROM MSB-25 REAR PANEL1 1314 25
