The ultra‑wave™ /Sonologic II/Weigh II Probus‑DP slave includes a high‑speed interface card using the Siemens

SPC3 chip set and RS485 transmission technology. The bus structure permits the addition and removal of

stations or step‑by‑step commissioning of the system. The card has the following capabilities and requirements:

ultra‑wave™ Compatibility EEPROM must be Rev. P or higher.

SonoII Compatibility EEPROM must be Rev. P or higher.

Transmission Speed Between 9.6 kbit/sec. and 12 Mbit/sec. The ultra‑wave™/ Sonologic II/Weigh II

Probus DP card will auto‑select the speed of the bus.

Network Topology Linear bus, active bus termination on both ends, stub lines only permitted for baud

rates of ≤ 1.5 Mbit/sec. (Termination not supplied)

Medium

Shielded twisted‑pair cable. Siemens 6XV1‑830‑OAH10, Belden 3079A or equivalent

Number of Stations 126 stations on one bus.

Connector

9‑pin D‑sub plug connector. Siemens Bus Connector 6ES7‑972‑OBA11‑OXAO or equivalent
