Here is a video diagram showing how a series of meters can be daisy chained together via RS485 communications:



All of the Omnimeters have an RS485 (A) terminal block and an RS485 (B) terminal block. You can just connect all of the RS485 As together and all of the RS485 Bs together. A to A to A and B to B to B in series.  Then connect the A wire to A on the EKM Push and the B wire to the B on the Push. It is really very simple and can be expanded in the future. You can connect up to 50 electric Omnimeters on over 4000 feet of wire to a single EKM Push2 gateway or up to 256 meters to a single EKM Push3 gateway.

Connecting to a USB Converter is done the same way; you connect all of the As together and all of the Bs together. Then connect the A line to A on the USB Converter and the B line to the B on the USB Converter. You can connect up to 256 electric meters on over 4000 feet of wire to a single USB Converter.


We use shielded CAT5 cable for the RS-485 data wire.  Inside of CAT5 there are 4 twisted pairs of wire, you will only need to use one of these twisted pairs for all meters connected to your communication device.  If there is a situation where it is un-economical to run CAT5 wire, you can make this data connection wireless using at least two EKM 485Bees.


Connecting to a iSerial is done the same way; you connect all of the As together and all of the Bs together. Then connect the A line to A on the iSerial and the B line to the B on the iSerial. It is really very simple and can be expanded in the future. You can connect up to 256 electric meters on over 4000 feet of wire to a single iSerial.
