Basler Electric multifunction relays have been certified by an independent testing service. Testing reports are available for download:
Modbus Protocol Modbus protocol was developed by Modicon for use in Programmable Logic Controllers (PLCs).
Modbus communications use a master-slave technique in which only the master can initiate a transaction. This transaction is called a query. When appropriate, a slave device responds to
the query. When a Modbusmaster communicates with a slave, information is provided or requested by the master.
Modbus has gained a high level of popularity for IED implementation. For more information, download the Modbus protocol manual for the:

ASCII Protocol ASCII stands for American Standard Code for Information Interchange. It consists of a set of codes used to represent letters, numbers,
control characters, and a few symbols.
ASCII data is in wide use when communicating with off-the-shelf terminal emulation programs such as ProComm Plus, Windows Terminal or Hyperterminal. Data can be sent and received from
IEDs using readable pneumonic words.
For details on setup, download PC-COM01, an application note on enabling ASCII communication with a relay via
Windows95 Hyperterminal.
