2.13.1 - CB15 Terminal Board
The CB15 terminal board connects to the LabJack UE9’s DB15 connector. It provides convenient screw terminal access to the 12
digital I/O available on the DB15 connector. The CB15 is designed to connect directly to the LabJack, or can connect via a
standard 15-line 1:1 male-female DB15 cable.
2.13.2 - RB12 Relay Board
The RB12 relay board provides a convenient interface for the UE9 to industry standard digital I/O modules, allowing electricians,
engineers, and other qualified individuals, to interface a LabJack with high voltages/currents. The RB12 relay board connects to
the DB15 connector on the LabJack, using the 12 EIO/CIO lines to control up to 12 I/O modules. Output or input types of digital I/O
modules can be used. The RB12 is designed to accept G4 series digital I/O modules from Opto22, and compatible modules from
other manufacturers such as the G5 series from Grayhill. Output modules are available with voltage ratings up to 200 VDC or 280
VAC, and current ratings up to 3.5 amps.
2.14 - OEM Connector Options
As of this writing, the UE9 is only produced in the normal form factor with screw-terminals and DB connectors, but the PCB does
have alternate holes available for 0.1” pin-header installation.
Connectors J2 and J3 provide pin-header alternatives to the DB15 and DB37 connectors:
3 - Operation
The following sections discuss command/response mode and stream mode.
Command/response mode is where communication is initiated by a command from the host which is followed by a response from
the LabJack. Command/response is generally used at 1000 scans/second or slower and is generally simpler than stream
