Quick Start Guide

Operating mode reference chart. All options are set via the DIP switches
Analog bi-direction: a 0V to 5V
analog input is connected to terminal
S1. 0V is full reverse, 5V is full
forward and 2.5V is stop
Analog single-direction: a 0V to 5V
analog input is connected to terminal
S1. 0V is stop and 5V is full forward.
R/C standard: An R/C servo signal is
connected to terminal S1. A 1000us
pulse is full reverse and a 2000us pulse
is full forward. 1500us is stop.
R/C auto-calibrate: An R/C servo
signal is connected to terminal S1. The
SyRen will automatically detect the
center and endpoints of the signal.
Simplified Serial, 38400 Baud: A
TTL level 8N1 serial data stream is
connected to terminal S1. Control is by
single byte commands: 0 is full reverse,
128 is stop and 255 is full forward.
Packetized Serial, address 128: A
TTL level 8N1 serial data stream is
connected to terminal S1. Control is via
a multi-byte packet.
Lithium cutoff option: When switch 3
is in the down position (in any
operating mode) the SyRen will shut
down at 3.0V per cell. This protects
lithium batteries from damage.
SyRen 50 features an additional 20+ operating modes and options not shown here. For the full manual,
