2. Set RW
- WU I <stid> <pn> 0 1
(Stid is in HEX, 17 dec = 11 hex)
(pn is 1 in most cases)
3. Write data into ST:
- WU W
4. Once the DACU has booted-up, put it into test mode by typing: TE 0
5. A configured DACU cannot maintain its uplink without being registered by the
management system. The DACU becomes registered when its ESN is entered into the
management system database. A registered ST can acquire the uplink and maintain
periodic information exchange with the shelf’s SC.
For testing type in the code relating to the system as set up i.e. LK 7 1 4 4 0 9 where
the first digit represents the RW code. The second digit the PN code. The third digit
the uplink modem rate (1 = 10kbit/s: 2 = 40kbit/s: 3 = 80kbits/s: 4 = 160kbit/s). The
fourth digit is the downlink rate (1 = 10kbit/s: 2 = 40kbit/s: 3 = 80kbits/s: 4 =
160kbit/s), The fifth digit is the overlay code (0 = default) and the final digit is the RF
channel within the RF operating band. In the example above the DACU is forced to
acquire on RW 7, PN 1, with Uplink and Downlink of 160kbit/s, using RF channel 9
within the RF band
6. Type W 426 to monitor link state
7. The DACU will return with:
Display Interpretation
D: 0426 0000 No Link
D: 0426 0101 Downlink Acquired
D: 0426 0303 Uplink Acquired (transitory state)
D: 0426 0B0B Uplink Acquired
D: 0426 0808 * Downlink has failed
D: 0426 0909 * Uplink has failed
*Note: relate to a link failure
8. Once the DACU acquires the link, the RX gain can be commissioned. If the link does
not acquire, then it will be necessary to change the RX gain through Sitespan.
9. Using Sitespan highlight the shelf, and edit ‘parent properties’.
10. Select ‘Airspan DA CT modem shelf’.
11. Adjust the ‘Rx Gain’ and select ‘OK’.
Note: To start with, set the RX gain to around 2200.
