coMMunIcatIons: rs-232 serIal
BE2 is configured via a three-wire, full-duplex dTe rS-232 port
that operates from 9600 to 115,200 Baud, 8 bits, no parity,
and one stop bit. Signal format is full-duplex, 3-wire, DTE using
rxd, Txd, and Gnd. Connections to the BE2 RS-232 port are
through J4, an rJ-11 connector. The BE2 Serial Cable Kit (Ser-
CK) contains a modular cable, and an adapter that connects to a
9-pin, Sub-d serial port connector (Com1, Com2, etc.) on PC's
and compatibles.
Ser-CK SerIal CaBle KIT
The Ser-CK provides connectivity between a d-Sub 9 male connector and the rJ-11
connector on the Be2. It includes an adapter that plugs into the Com1 (or other) port
of a PC and uses common modular cable to connect to the BE2. The connections are
shown in the diagram below.

aSCII CommunICaTIonS
The Copley aSCII Interface is a set of aSCII format commands that can be used to operate and monitor Copley Controls
accelnet, Stepnet, and Be2 series amplifiers over an rS-232 serial connection. for instance, after basic amplifier
configuration values have been programmed using Cme 2, a control program can use the aSCII Interface to:
• enable the amplifier in Programmed Position mode.
• Home the axis.
• Issue a series of move commands while monitoring position, velocity, and other run-time variables.
The Baud rate defaults to 9,600 after power-on or reset and is programmable up to 115,200 thereafter.
After power-on, reset, or transmission of a Break character, the Baud rate will be 9,600. once communication has been
established at this speed, the Baud rate can be changed to a higher rate (19,200, 57,600, 115,200).
aSCII parameter 0x90 holds the Baud rate data. To set the rate to 115,200 enter this line from a terminal:
s r0x90 115200 <enter>
Then, change the Baud rate in the computer/controller to the new number and communicate at that rate.

USB To RS-232 ADAPTERS
These may or may not have the speed to work at the
115,200 Baud rate which gives the best results with
CME2. Users have reported that adapters using the
fTdI chipset work well with Cme2
