Connectors and Cables
WBK40 and WBK41 are connected to StrainBook in the same manner.
The relevant WBK connectors [located on the rear panel of the WBK modules] are as follows:
•
POWER IN [DIN5] connects to a 10 to 30 VDC source. Typically uses a TR-40U power
supply.
•
PARALLEL PORT [DB25] connects to the StrainBook’s EXPANSION PORT. Typically
connects via a CA-35-12 cable.
•
P1 – ANALOG EXPANSION PORT [DB37] connects to an optional DBK84 (14 Channel
thermocouple module). Typically uses a CA-37-x cable, where “x” equals the number of
expansion devices. Connects to an optional DBK84 (14 Channel thermocouple module).
Typically uses a CA-37-x cable, where “x” equals the number of analog expansion devices.
•
P2 – DIGITAL EXPANSION PORT [DB37] [
included on WBK41, but not on WBK40
].
Can be used to connect the WBK41 to an optional DBK20 Series device. The connection is
typically made via a CA-37-x ribbon cable, where “x” equals the number of digital expansion
devices. If P2 is not used for DBK20 Series expansion, it allows for 24 bits of Digital I/O,
which is in addition to the 16 bits of Digital I/O that are provided by front panel terminal
blocks.
•
SYNC – Use either of the 2 SYNC ports and a CA-74-1 or CA-74-5 cable to provide a
synchronization link from a WBK40 [or WBK41] module to the host StrainBook.
The relevant StrainBook connectors [located on the StrainBook/616 rear panel] are:
•
POWER IN [DIN5] connects to a 10 to 30 VDC source. Typically uses a TR-40U power
supply.
•
ETHERNET connects to a PC’s 10/100BaseT Ethernet port, or to a 10/100BaseT Ethernet
network.
•
SYNC – Use either of the 2 SYNC ports and a CA-74-1 or CA-74-5 cable to provide a
synchronization link from the StrainBook to a WBK40 [or WBK41] module.
•
EXPANSION PORT [DB25] connects to the PARALLEL PORT on the WBK40 or
WBK41. Typically connects via a CA-35-12 cable.
Prior to connecting your devices to power, calculate your system’s power
requirements as discussed in upcoming section of this chapter.
CE Compliance
If your system needs to be CE Compliant, refer to the Declaration of Conformity
for each system component. Also, refer to Chapter 9, CE Compliance and Noise
Considerations
