Peer-to-Peer Communications Option
655-RS232
Description
The 5703/2 Peer-to-Peer Communications option provides the capability for fully digital
reference control between motor controllers through the use of a fiber optic communications medium. A reference signal is passed between drives through a fiber optic link and
the P3 serial port of each drive. The option mounts directly to the type TS 32 or TS 35
DIN rail. It is powered from the motor controller 24 VDC power supply through the P3 port
connection. The 5703/2 Peer-to-Peer Communications option provides the following
advantages:
• 16-bit reference signal
• Configuration for master/slave operation
• Fully configurable input and output signals.
• An additional fiber optic transmitter for re-transmitting the incoming signal or
transmitting the output signal to a second destination.
This option can be used with:
• SSD 590 series controllers
• 590 DRV Digital DC Drives

Installation Information
!
Electrical Shock Hazard
Isolate all sources of power before installing this option. Severe injury or
death could result from unintended actuation of controlled equipment.
Mounting Instructions:
1. Attach the unit to type TS 32 or TS 35 DIN rail. It must not be placed
further than 400 mm from the RS-232 serial port on the main control
board.
!
Static Sensitive Parts The 5703/2 contains ESD (electrostatic
discharge) sensitive parts. Observe
static control precautions when handling,
installing, and servicing this assembly.
2. Connect the 4-wire cable (CM057375U040) to the RS-232 serial port on
the main control board. Be sure to route the cable to permit the control
door to be opened (see figure 1).
Note: Do not mount the 5703/2 where the cable will be subject to
strong electrical or magnetic fields.
3. Prepare the receiver end of the fiber optic cable with the Fiber Optic
Cable Cutting Kit (LA385204). Loosen the screws on the hardened
receiver and push the cable until it stops. While keeping pressure on the
cable, tighten the two screws evenly to assure metal to metal contact of
the connector housing.
4. Use Thomas and Betts plugs for the transmitter fiber optic connections
(red connectors) for the destination motor controllers. Be careful not to
bend the fiber optic cable tighter than a 2-inch bend radius when routing
the cable.
Note: Do not tie the fiber optic cables to the control harness. This
will kink the cable and attenuate the transmission.
Additional Instructions:
The 5703/2 requires motor controller software configuration for proper
operation. The default settings in the SSD 590 series controller for the
5703/2 are:

To use the 5703, set the 5703 MODE to 'MASTER' or 'SLAVE.' If a motor
controller is to be a 'SLAVE' then the 'SETPT. RATIO' must be set to a value,
typically 1.0000.
Note: Remember to save the parameters in the controller and update the
configuration record once you have completed your configuration. See
the motor controller product manual for more information.

Application Notes
The figure below shows the 5703/2 Peer-to-Peer Communications option. The link position determines the signal
transmitted by TX2. When the link connects pins 1 and 2, TX2 re-transmits the input signal from receiver, RX1. When the
link connects pins 2 and 3, TX2 transmits the same signal as TX1. All the remaining configurations are set by software in
the motor controller.

Figure 4 shows a typical 5703/2 application. The master drive sends a speed setpoint to slave drives 1 and 3. The link is
set to 2 and 3 as shown. Slave drive 3 sends a new setpoint to slave drive 4. It also re-transmits its input setpoint from
the master drive to slave drive 5. The link is set to 1 and 2 as shown.
