# Buka daughterboard dari motherboard USRP.
 +
# Untuk N2XX: Ubah jumper J510 di motherboard dari 1-2 ke 2-3 untuk menswitch dari external ref clock 10MHz ke GPSDO 10MHz Ref Clock.
 +
# Sekrup modul GPSDO di tempat yang di sediakan. Sekrup dilakukan untuk menjaga agar tidak goyang dengan getaran.
 +
# Sambungkan kabel power GPSDO ke J509 (N2XX) di motherboard, dan ke konektor D di modul GPSDO.
 +
# Sambungkan SMB ke kabel SMA antara konektor B dan J506 (N2XX-PPS2).
 +
# Sambungkan SMB ke kabel SMA antara konektor C dan J5-7 (CLK REF2).
 +
# Dalam kit termasuk tiga kabel serial yang tidak dapat di tukar2 untuk digunakan di berbagai revisi / model USRP. Kabel 8cm untuk N2XX revisi 4 dan E1XX revisi 5 dan atasnya. Kabel 22cm dengan kabel hitam tersambung di tengah pin untuk USRP N2xx revisi 2 & 3.
 +
# USRP N2xx Rev 4 atau yang lebih tinggi: Temukan J312 di belakang  motherboard dekat sambungan power GPSDO dan sambungkan ujung dari kabel 8cm kepadanya.
 +
# Sambungkan ujung satunya dari kabel serial ke konektor A di modul GPSDO. Pastikan kabel hitam tersambung ke pin 2, jika tidak maka kemungkinan kabel salah atau konektor terbalik.
 +
# Buka mur & baut dari MMCA ke kepala SMA. Sambungkan ke konektor E dan masukan sambungan kepala SMA melalui lubang ke belakang panel. Keraskan mur & baud.
 +
# Sekarang masukan semua daughterboard dan tekan semua kabel di bawahnya.

Instructions:
+
===GPRS===
−
1. Remove the daughterboard from the USRP motherboard if present.
 
−
2. USRP N2xx Only: Move J510 jumper on the motherboard from 1-2 to 2-3 in order to switch from external 10 MHz Ref Clock to GPSDO’s 10 MHz Ref Clock
 
−
3. Screw the GPSDO module in place with the screws provided. The screws are treated to avoid loosening with vibration.
 
−
4. Connect the GPSDO power cable to J509 (N200) / J101 (E1xx) on the motherboard, and then to connector D on the GPSDO module
 
−
5. Connect an SMB to SMA cable between connectors B and J506 (N200-PPS2) / J13 (E100–PPS)
 
−
6. Connect an SMB to SMA cable between connectors C and J507 (CLK REF2) / J10 (E100–REF IN)
 
−
7. The kit includes three non interchangeable serial cables to be used with different USRP revisions and/or models. The 8cm long cable is for N200 series revision 4 or above and the E100 series revision 5 or above. The 22cm long cable with the black wire connected to the center pin on both ends of the cable is for the USRP N200 revisions 2 & 3. The 22cm long cable with a colored dot on the connector that has ground (black wire) on pin 1 is for the USRP E100 revision 4.
 
−
8. USRP N2xx Rev 2 & 3: Locate J312 on the front of the motherboard and connect either end of the appropriate 22cm long serial cable to it. If J312 on your USRP isn’t a keyed connector, please ensure to connect pin1 (TX) of connector A to the RX pin on J312.
 
−
9. USRP N2xx Rev 4 or higher: Locate J312 on the back of the motherboard near the GPSDO power connector and connect either end of the 8cm long cable to it.

Kit Berisi 

1 GPSDO modul
1 Kabel Power (2 wire)
2 Kabel RS 232, 22cm (3 wire)
1 Kabel RS 232, 8cm (3 wire)
2 SMB right angle ke kabel SMA right angle
1 MMCX to SMA Bulkhead cable
2 Sekrup

Catatan: Lakukan sambungan dengan kondisi USRP power off.

Gpsdo-block.jpeg

Konektor: 

A. RS-232 (Pins: 1. TX, 2. GND, 3. RX)
B. 1 PPS
C. 10 MHz Ref Clock
D. Power (Pins: 1. GND, 2. GND, 3. +6V)
E. GPS Antenna

Instruksi:

  1. Buka daughterboard dari motherboard USRP.
  2. Untuk N2XX: Ubah jumper J510 di motherboard dari 1-2 ke 2-3 untuk menswitch dari external ref clock 10MHz ke GPSDO 10MHz Ref Clock.
  3. Sekrup modul GPSDO di tempat yang di sediakan. Sekrup dilakukan untuk menjaga agar tidak goyang dengan getaran.
  4. Sambungkan kabel power GPSDO ke J509 (N2XX) di motherboard, dan ke konektor D di modul GPSDO.
  5. Sambungkan SMB ke kabel SMA antara konektor B dan J506 (N2XX-PPS2).
  6. Sambungkan SMB ke kabel SMA antara konektor C dan J5-7 (CLK REF2).
  7. Dalam kit termasuk tiga kabel serial yang tidak dapat di tukar2 untuk digunakan di berbagai revisi / model USRP. Kabel 8cm untuk N2XX revisi 4 dan E1XX revisi 5 dan atasnya. Kabel 22cm dengan kabel hitam tersambung di tengah pin untuk USRP N2xx revisi 2 & 3.
  8. USRP N2xx Rev 4 atau yang lebih tinggi: Temukan J312 di belakang motherboard dekat sambungan power GPSDO dan sambungkan ujung dari kabel 8cm kepadanya.
  9. Sambungkan ujung satunya dari kabel serial ke konektor A di modul GPSDO. Pastikan kabel hitam tersambung ke pin 2, jika tidak maka kemungkinan kabel salah atau konektor terbalik.
  10. Buka mur & baut dari MMCA ke kepala SMA. Sambungkan ke konektor E dan masukan sambungan kepala SMA melalui lubang ke belakang panel. Keraskan mur & baud.
  11. Sekarang masukan semua daughterboard dan tekan semua kabel di bawahnya.
