D17XX OEM Integration v0.1 Mounting Considerations The following steps should be followed when mounting the D17XX PCB. Note: Should these guidelines be ignored, performance may suffer and the board may be damaged permanently. Heat sinking The Microprocessor (U28D17XX) and FPGA (U3D17XX) require thorough heat sinking to a metal mounting plate, as indicated in Figure 3. Failure to install such provisions will damage both components.
D17XX OEM Integration v0.1 Turning On the System [Extract taken from the D1705 TP v1.1 and as such, Tera Term figures will refer to this variant] 1. Test Setup Connect the following cables to the D17XX PCB, as shown in Figure 5. Power Cable from external PSU to J2 o Set supply to 12V 1.
D17XX OEM Integration v0.1 Figure 6: Tera Term serial port settings Power up the unit. In the Tera Term window, press ctrl d, c and then u during boot-up to navigate to the unit type selection. Select the option that applies to unit under test and power down the unit. 2.2 Software updates If an update of the board’s software is required at any time, . Power down the unit. 3.
D17XX OEM Integration v0.1 Adjust the Signal Generator RF Amplitude until the displayed Marker Level is at -85dB. Leave the amplitude set at this level. Set the Generator output to OFF. Swap the 50Ω Termination (or 20dB Attenuator) and the connection to the Analyser. Set the Signal Generator output to ON and check the Marker level on the Analyser is within 0.3dB of the level set previously. Set the Signal Generator output to OFF.
D17XX OEM Integration v0.1 Set the Signal Generator to the initial test frequency displayed on Tera Term (1250MHz in Figure 8) plus an additional 200kHz and set RF Output to ON. Press x to take measurements. ….. Figure 9: Noise Figure test complete Press x to calculate the Noise Figure, turn the RF output OFF and allow the readings to stabilise.
D17XX OEM Integration v0.1 Set the RF output of the Signal Generator to ON and verify the gain lies within the limits laid out in Table 3. Frequency [MHz] Max Gain [dB] Min Gain [dB] 1250 -22 -27 1340 -19 -24 1400 -20.5 -25.5 1450 -23 -28 Table 3: LNA gain limits Press x to continue through to the next gain frequency, remembering to add 200kHz to all indicated test frequencies on the Signal Generator and refer to Table 3 to verify the limits.
D17XX OEM Integration v0.1 The output power needs to be checked over a range of frequencies automatically predefined in the software relating to the particular type of the unit. Using the o and p keys to adjust the output power, confirm on the Power Meter that the minimum RF Output the D17XX can provide is >21.5dBm, regardless of Tera Term setting. Adjust the output power at the first trim frequency to 20.0dBm ± 0.25dB in Tera Term. Press x and proceed to the next trim frequency.
D17XX OEM Integration v0.1 Navigate to global Settings and click on the Set Clock button. Set the clock to the current date and time, and power down the D17XX. 7.

Direct connection to PC Should there be a need for direct connection to a PC without a network, DHCP should be disabled on the D17XX and the user should assign a static IP address to the unit.
D17XX OEM Integration v0.1 Z PQR ; X ETX 20h-7Eh 20h-7Eh 3Bh 80h-FFh 03h Status BYTE Data –Optional, variable length Separator Checksum End byte The checksum byte is a summation of all bytes in the packet, not including the start (02h) and end (03h) bytes. The result is then modified by forcing bit 7 high to prevent ASCII control characters from being sent. The resulting checksum is in the range of 80h - FFh.
