Rear Panel Connectors
WBK41, Rear Panel Connectors
Note that WBK40’s Rear Panel is identical, except it has no P2 connector. Page 1 includes a photo of the WBK40 rear panel.
Note:
The P2 Connector
does not apply to
WBK40.
Item Description
P1
(see page 26 for
pinout)
P1 is an Analog Expansion Port. This DB37 connector is used to connect the WBK40 or WBK41 to an
optional DBK84, 14-Channel Thermocouple Module. The connection is typically made via a CA-37-x
ribbon cable, where “x” equals the number of analog expansion devices.
P2 (WBK41 Only)
(see page 27 for
pinout)
P2 is a Digital Expansion Port, which is available on the WBK41, but not on the WBK40. This DB37
connector 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.
POWER [switch] Two-position rocker switch with labels “0” for “Power OFF” and “1” for “Power ON.”
POWER IN A DIN5 connector which accepts power of +10 to +30 VDC. Power is typically supplied via a
TR-40U power adapter.
LEDs ACTIVE – Lights when a sample is being converted by the Analog-to-Digital Converter (ADC) that resides
inside the WBK40 or WBK41.
ONLINE – Lights when software is communicating with the WBK40 or WBK41.
POWER – Lights when power is available to the WBK40 or WBK41, and the Power switch is in
the “1” (Power ON) position.
SYNC Ports (2) Two SYNC Ports are available to synchronize sampling with other connected devices that have SYNC
ports, for example, the WaveBook/516E. Cable CA-74-1 or CA-74-5 is typically used to provide
a synchronization link from a WBK40 [or WBK41] module to another device.
PARALLEL PORT The Parallel Port is a DB25 connector that is used to connect the WBK40 [or WBK41] to a
WaveBook/516E or WBK25 Ethernet Interface Module.
