How many RS485 devices can the USG-1’s transceiver handle?

The USG-1’s transceiver is capable of handling connection of up to 32 RS485 devices.

When connecting multiple RS485 devices, the exact number possible will depend on the total cable length, cable quality, and instrument inputs. Longer total cable lengths, poor cable resistance and capacitance, and RS485 device inputs not meeting the RS485 specifications will reduce the maximum number of devices drivable.

PLEASE NOTE THAT THE USG-1 IS A RETIRED PRODUCT.

The USG-1 has been replaced with the USG-2
