TB13 does not physically exist on
DBK215. A silkscreen of TB13 is
present as a visual aid to signal
routing and configuration.
A header located beneath TB14 and
TB16 is used to set the BNC
channels to Single-Ended or to
Differential. Simply place channel’s
2-pin jumper in the appropriate
position (SE or DIFF).

BNC channels A through D are configured on a per-channel basis by the user. TB15 is a routing
terminal block used to connect BNCs (A thru D) to the desired signals, which are selected via a second
DBK215 terminal block. For example: a user could run a wire from BNCA+ to TB4 screw terminal
“TMR0” and BNCA- to TB4 DGND to create a BNC timer connection.
Accessory Wire Kit, p/n 1139-0800 includes jumper wires and a screwdriver.
