Page 11: Cables
3.1 Motor and Limit/Datum cables Motor and limit/datum cables fitted with connectors to plug into the rear panel of the SimStep may be specified. The available lengths are shown below. The motor cables have a connector on both ends, which can be connected either to the connector fitted to the stepper motor or to the stepper motor wires via an MSA889 Junction Box. -
Page 12: Encoder Cables
3.3 Encoder Cables SimStep can be connected to the encoder via an encoder cable that is equipped with connectors at each end. One connector plugs into the controller, the other into the motor- encoder extension cable as shown in fig 3.2. -

Any suitable communication programme can be used to communicate with the SimStep controller. For example, the MyTerminal programme (available from www.SimStep.co.uk) or the Windows Hyper Terminal programme can be used to make the communications link. Whichever software is used, the communications interface is set by default, as follows: Baud Rate... - Page 25 1 2 3 4 5 6 7 8 ULOAD LD2 LD3 SWAP8 Fig. 8.2 PM600 Switch Positions Fig. 8.3 Positions of PM600 Switches SW1, SW2 and SW3 SimStep Manual - 3400 Iss.

Page 26: General Command Structure
2MA-2000 Move Axis 2 to absolute position –2000 steps Output the encoder position of Axis 2 SimStep controller responds to all commands once the command has been accepted. However, not all commands can be accepted immediately. For example, a move command sent whilst a previous command is still taking place, will be delayed until the previous one is finished. -
Page 27: O Cable And Breakout Box
An I/O cable with the ‘breakout’ DIN rail mounting terminal box can be used to interface to SimStep without needing to make a special cable. The I/O breakout box features screw terminals to enable the 16 Digital I/O to be connected. -
Page 28: Isolation
This supply can either be a separate external supply or the SimStep’s internal +24V supply. If the internal supply is used, then the WP-com terminal must be connected the +VLL terminal on the Breakout box and the RP-com terminal must be connected the 0V terminal on the Breakout box. -
Page 29: Write Ports
9.4 Write Ports The write ports can be connected to an indicator (LED), an opto-isolator, a low-current relay or another SimStep’s read port. The WP(bit pattern) command is used to write to the output port. The bit pattern is specified as an eight digit binary number. The digits will be either characters 0, 1 or 2 starting with write port 8 through to 1. -
