PRODUCT OVERVIEW
The GSM4, together with the optional PSU4 power supply, provides a comprehensive facility for controlling 4
or 8 wire Bipolar driven stepper motors. Up to 4 GSM4 cards can be daisy-chained to control up to 4 motors.
Simple software commands can be sent from a PC via the RS232 serial port to the GSM4 to control motor
direction, number of steps, start and stop ramp length and slope, motor current and ½ / full step. All commands
carry address information.
On board settings include card address (0, 1, 2, 3) motor current (set to suit motor specification) and number of
steps / second (speed).
SPECIFICATION
MOTOR DRIVE: 4 or 8 wire bipolar current switching, up to 1.5 ampere / phase Voltage 12 to 40 Volts DC
(maximum).
INTERFACE: RS232C 9600 Baud, DTE via 9 pin “D” connector, Tx, Rx & GND active (Null modem) daisy-
chained from card to card.
ADDRESS: On board card address selection 0, 1, 2, 3. Software commands include card address.
MOTOR CONTROL: Current, speed, direction, ½ current, boost, ½ / full step, number of steps (0-99999),
ramp (length and slope), limit and enable switch provision.
