Configuring the SDR-2400/SM-SDR-2400
Linking up two units
To initialize and link-up two SDR-2400/SM-SDR-2400 units, follow these steps:
1. After booting up, log in and initialize RF components.
2. Configure SDR-2400/SM-SDR-2400 into base station or locomotive mode.
For base station:
Driver uses the command:
SDR-2400 > cfg_ad9361
Then it broadcasts time slot table information via beacon packets.
For locomotive:
Driver uses the command reg_wr to set bit 3 of $REG_CARRIER_CFG:
SDR-2400 > reg_wr $REG_CARRIER_CFG 0x0001F0F8
3. The locomotive detects the beacon and uses it to program the time slot table, then sends asso-
ciation packets to request link-up.
4. The base station exchanges device information with the locomotive (MAC address, client ID, and
so forth). Then the link-up process completes. Both SDR-2400 should be able to ping each other.
