Both serial ports are RS485 (COM1 and COM2). The documented MBus acquisition is for four-wire MBus devices. Do not connect two-wire MBus devices directly to these RS485 ports.

Model notes · Model designation: 1 Ethernet port and 2 serial ports. The manufacturer confirms meter-oriented acquisition with MBus and DLT645 added to the Lite baseline. The listed acquisition protocols are explicitly documented in both catalog editions; the Lite baseline does not imply every meter driver. Check the matching datasheet for forwarding capabilities and power requirements.

Recorded capacity

Capacity to confirm

Both serial ports are RS485 (COM1 and COM2). The documented MBus acquisition is for four-wire MBus devices. Do not connect two-wire MBus devices directly to these RS485 ports.

Check before connecting

Check the device brand, model, driver version and interface. Use the wiring diagram to confirm terminals and port assignments.
Prepare a point list with addresses or objects, data types, byte order, units and read/write permissions.
Confirm the role at each end and the device address, serial settings, or IP address and port.
Check point count, device count and physical port count separately, then confirm capacity for the actual data volume.

How to choose within a series

Match device-side protocols and the host system first, then check ports, wireless connections and capacity. Candidates below use confirmed model specifications.

Current model groupBAC1002

You need multiple serial and Ethernet protocols

Check models confirmed to cover all acquisition protocols for serial and Ethernet connections. Check protocol scope and physical port counts separately. Confirm dedicated CAN, KNX TP and 2-wire MBus connections for the specific model.

What does X mean, and how do acquisition and forwarding protocols differ?

X denotes the acquisition-side protocols. Also check forwarding protocols, communication roles, physical interface types and port counts.

Read the full answer

How should serial, CAN, KNX and MBus port counts be checked?

Check physical interfaces, protocol support and shared-port arrangements separately, especially native two-wire MBus versus four-wire devices connected through RS485.
