Serial Port
Configuration
Baud 9600, fixed
Start bits 1
Data bits 8
Stop bits 1
Parity None
2.8 Serial Communication Settings
The serial interface operates at RS-232 levels with
fixed parameters of 9600 baud, 1 start bit, 8 data bits,
1 stop bit, and no parity. The interface uses only three
wires, for received data, transmitted data, and ground.
In general writing data must start with a write
command byte and be followed by a data byte.
Reading a camera register requires only a single read
command byte.
WARNING:
Due to initialization sequencing after power-
up, no commands should be sent to the camera for a
minimum of 1 second after power up.
Serial Cable Source
The remote interface connector, on the cameras rear panel,
is specified as a low-profile RJ-11 modular connector. The
connector is a 6-position model, but only the center four
positions are populated with contacts. It will mate with
either the 4-position or 6-position cable plugs. This type of
connector typically requires special assembly tools;
complete cable assemblies are available from suppliers
such as Digi-Key:

cable part number:
H2643-14-ND (14 feet)
DALSA provides serial cables in 3 lengths: 10’, 20’ and 50’. Part number CL-31-00004-xx
(where xx refers to the cable length in feet).
2.9 TTL Trigger Input and Output
Connector
The camera uses an SMA connector (labeled TRIGGER IN) to allow the user to provide a standard
TTL signal to control camera integration and readout. The input is high impedance (>10K)
allowing the user to terminate at the SMA input as needed. The camera has another SMA
connector (TRIGGER OUT) that provides a standard TTL output which is high whenever the
camera is integrating.
