ISSUE/REVISION DATE: 25 JULY 2007 TECHNICAL MANUAL 2.0 DDC Hardware Interface 2.1 DDC General Specifications The DDC module uses a Motorola 5282, 32-Bit processor core module with Ethernet on a Carrier PCA. The Carrier PCA handles all power supply requirements and signal conditioning for the core processor module. A Complex Programmable Logic Device (CPLD) is included on the carrier PCA to handle logic and expansion. Serial ports are buffered on the carrier PCA and routed to the core processor module.

ISSUE/REVISION DATE: 25 JULY 2007 TECHNICAL MANUAL DDC, OPEN The sixteen wide range discrete DDC inputs are connected to the 37 pin D connector J4 . Each group of four discrete inputs has an associated pull-up selector, JP1 – JP4. By connecting a jumper between pins 1 & 2 a pull-up will be supplied via 4.7K Ohm resistor to +5VDC. Connecting a jumper between pins 2 & 3 will supply a +24 VDC pull-up voltage via the same 4.7K Ohm resistor. Each discrete input is buffered by a 4.
ISSUE/REVISION DATE: 25 JULY 2007 TECHNICAL MANUAL JP1-JP4 LOCATION The eight buffered TTL outputs are connected to the 37 pin D connector, J4, visible in Figure 4. The eight analog to digital inputs (ADC) with a resolution of 10 bits are connected to the 37 pin D connector J3, visible in Figure 3. Each input is filtered by a .1 mF capacitor. The reference voltage for the ADC is 5.0 volts. Input range is from 0 to +5 VDC.
TECHNICAL MANUAL AUTO-RANGING DC VOLTMETER The DDC module incorporates a digital trigger protection circuit that allows for the input of two separate triggers. Trigger inputs are on 37 pin D connector J3 pins 10 and 11. Each trigger input is 50 Ohm terminated and can take trigger pulses up to 25 V peak with duty up to 50% without damage to circuits. PRF maximums are set in memory and can be changed at any time using the Ethernet or serial interface.

ISSUE/REVISION DATE: 25 JULY 2007 TECHNICAL MANUAL 2.5 Ethernet (J5) The Ethernet jack (J5) is located in the rear face of the DDC. This is a standard 10/100-Base-T Ethernet connection jack. 3.0 Software Interface There are three communication interfaces that software can use to communicate with the DDC. Serial and Ethernet interfaces use identical formats for command and control functions in the DDC. 3.1 Serial Control RS232 serial control is through the console port, Port 0.
ISSUE/REVISION DATE: 25 JULY 2007 TECHNICAL MANUAL 4.0 Troubleshooting the DDC 4.1 LED indicators LED1 & 2 The DDC module has three LEDs that are used for the following indications: Indicator Function LED 1 Processor running. This LED should blink regularly. LED 2 Communications link established. This LED should blink regularly. RS232 RS232 receive level present. This LED should be lit when a good RS232 receive level is detected on any of the three RS232 ports. Rev No.
ISSUE/REVISION DATE: 25 JULY 2007 TECHNICAL MANUAL Appendix A – Software Loading Introduction The DRCP firmware and boot configuration data is stored in an on-board flash memory. This document is to be used as a guide for configuration and downloading of the application firmware. A processor will need its configuration, modified when it is a new board without an application and initial configuration or when a configuration item such as the network configuration needs to be changed.
ISSUE/REVISION DATE: 25 JULY 2007 TECHNICAL MANUAL Interrupting the boot process WAITING TO START When the waiting to start message appears the A character must be sent to the device to interrupt the boot process and enter the configuration screen. Once the boot process has been successfully interrupted, a command prompt will be displayed as shown below. At this point you are ready to change configuration data or download a new application to the module. MONITOR PROMPT Rev No.
ISSUE/REVISION DATE: 25 JULY 2007 TECHNICAL MANUAL Operational Parameter Configuration SETUP MENU The menu is operated by simply entering the number or letter preceding the desired menu option. Once all desired changes are made simply entering an S will save the options to flash and reboot the processor. Network Configuration 1) IP ADDRESS When prompted enter the IP address in the standard IPv4 dotted decimal notation ex: 10.60.5.10.
ISSUE/REVISION DATE: 25 JULY 2007 TECHNICAL MANUAL ETHERNET MAC ADDRESS LABEL In most cases entering of the MAC address will not be required. Additional Configuration Besides network configuration it is necessary to configure a few other operating parameters. Wait The Wait menu item controls how long the processor waits in seconds before beginning execution of the application stored in flash.
ISSUE/REVISION DATE: 25 JULY 2007 TECHNICAL MANUAL Watch Dog The Watch Dog menu item enables or disables the on chip watchdog timer. This item should be enabled after downloading the application firmware. If this option is enabled and changes need to be made via the boot monitor console, this item should be changed and saved first. Failure to disable the watchdog will result in the repeated resetting of the processor while in the boot monitor console.
