2 MIU-10X /5XS SETUP AND CFIGURATI MIU-10X Configuration and Diagnostics Screen Upon boot-up the MIU-10X first runs a self-diagnosis routine to determine if the keypad, LCD screen, and communications ports are operational. If there are errors during the initialization process, the user is queried if a reinitialization attempt should be performed. If no initialization errors occurred, or if a re-initialization is not requested, the user is next presented the option of viewing a Diagnosis and Configuration mode. To enter the Diagnostic and Configuration mode screen you must press a key when the message PRESS ANY KEY FOR DIAGNOSTICS is being displayed on the LCD s screen. If the prompt to enter the Diagnostics and Configuration screen is missed, it will be necessary to re-power the MIU (Note MIU must be left off for 5-10 seconds) to enter this mode again as the MIU will enter an AWAITING HOST mode. The Diagnostic and Configuration screens allow the user to test the keypad and display, test the UARTs, monitor Host communications, and Gageport baud rates. The system parameters, once set, are stored in battery backed memory and it will not be required to re-enter these unless either the battery is removed or if the MIU s operating characteristics are to be changed. For MIU setup press 7 when main diagnostics menu is displayed. Printer should be left at the default of 0. Gage/Printer also should be left at the default of 0. Jumper Configuration Jumpers JP1 - JP16 Jumpers JP1 through JP15 are provided to allow for single connection of ground references for the digital input signals. Shunt jumper JP1 to connect the ground of Digital Input #1 to the ground of Digital Input #2, shunt jumper JP2 to connect Digital Input #2 s ground to Digital Input # 3, and etc. This sequence continues through Jumper JP15 which connects Digital Input # 15 s ground to Digital Input # 16 s. Jumper JP18 (Default is ) Jumper JP18 (not typically used) connects the ground of Digital Input # 16 to the MIU-10X s digital ground plane itself. If all the digital input signals have a common ground, an installer can use jumpers JP1 through JP16 and JP18 to provide a single ground to all the MIU s digital inputs with a single wire. Jumper JX13 (Default is NC) DO NOT INSTALL SHUNT For External PC Speaker only. Jumper JX2 (Default is Off) - Connects Earth Ground to Internal Ground Jumper JX12A (Default is 2-3) Floppy/Keyboard Enable (Factory Use Only) Jumper JX12B (Default is 1-2) FDRQ/DRQ0 (Factory Use Only) Jumper JX12C (Default is 1-2) FDACK/DACK0 (Factory Use Only) Jumper JP17 (Default is Off) - Provided for end of line termination for MIU communications. Warning!! Only install in last MIU on each channel. Jumper JX7 (Default is Off) Provided to configure COM3 for 485 2 wire Jumper JX8 (Default is Off) Provided to configure COM3 for 485 2 wire Jumper JX14A (Default is Off) High speed Analog for IRQ7 Jumper JX14P (Default is Off) Parallel Printer for IRQ7
Jumper JX14C (Default is On) Com 4 for IRQ7 Jumper JX3 (Default is 2-3) Com3 / High Speed for IRQ9 Jumper JX6 (Default is Off) - Provided to configure COM4 for 485 2 wire Jumper JX1 (Default is Off) - Provided to configure COM4 for 485 2 wire Jumper JX11 (Default is Off) RTS-CTS Connection for Com4 Jumper JA1 thru JA14 (Default is On For Thermocouples only) Provides a ground reference for Thermocouples. JA1=An1, JA2=An2, JA3=An3, JA4=An4, JA5=An5, JA8=An6, JA9=An7, JA10=An8, JA11=An9, JA12=An10, JA13=An11, JA14=An12. Analog Gain Modification The analog SIMs each contain six instrumentation amplifiers, and each of these amps have a fixed 50K input impedance. The gain of an analog channel can be changed by simply replacing the gain resistor, located on the SIMM, (Rg) with a different value. The gain resistor is determined by the formula: Rg = 50000/((10/Vs)-1) -Where Vs is the maximum voltage the sensor will produce. Example: Pressure Transducer rated at 3.0 mv/v 10X excitation voltage of 10 volts Vs=10V x 3.0 mv/v = 30 mv 3

MIU 10X ANALOG SIMM SETUP AND CALIBRATI CH1 CH2 CH3 CH4 CH5 CH6 Figure 1 1. J and K type thermocouples both use 182 ohm 1% precision resistor. Prior to calibration allow at least one hour for internal temperature of MIU to stabilize. From the factory each SIM is set up for (4) Thermocouples and (2) Linear devices. The linear is set up for a 3mV/V device. 2. Each channel must have gain and offset set in System Manager MIU (F4, F8, F2) as follows. Gain Offset J or K type 1.00 0 3. Gains must be set as stated prior to calibration. Calibrate by changing offset to match any differences between simulator or press and MIU. Offset is changed in System Manager MIU (F4, F8, F2). Gain resistors and current loop load resistors are located on the SIM. See table below for the designator for each.
