Configuring the 268XA

You must configure the 268XA device before using it. The following sections provide basic configuration information. Refer to the Users Manual for additional configuration information.

Reviewing and Setting the Base Channel Number

Perform the procedure below to review or set the Base Channel Number (BCN). The BCN identifies the device. The BCN is also the first two digits of the Global Channel Number (GCN), which uniquely identifies each device channel. For example, a GCN of 27116 indicates device 27 and analog channel 116. (See Figure 1 for examples.)

BCN Range The BCN can be any number from 01 to 99. If you plan to install Fluke DAQ software for isolated network operation, each device on the network must have a unique BCN.

BCN Review or Set identifier The REVIEW annunciator displays when reviewing the BCN; the SET annunciator displays when setting the BCN.

Table 1. Reviewing and Setting the Base Channel Number

Press the COMM key to review the Base Channel Number (BCN), or press and hold the COMM key for 3 seconds to set the BCN.

Press the up/down arrow keys until bASE (Base Channel Number) appears

in the primary display (COMM appears in the secondary display).

Press the ENTER key. bASE appears in the secondary display and the current BCN (two digits) in the primary display.

For BCN set procedures, press the left/right arrow keys to select the BCN 10s

or 1s digit position (highlighted).

Press the up/down arrow keys to select the desired number, 0 to 9, for the

positioned BCN digit. In this manner, set both BCN digits.

Press the ENTER key to exit. (Pressing any other function key will cancel set operations.)
