Channel Connections
Channels on the Terminal Panel correspond directly to channels on the
E1476A terminal module. For example, the channel 2 H, L, and G
connections on the E1476A multiplexer have corresponding channel 2
H, L, and G connections on the Terminal Panel.
Since a single Terminal Panel has a total of 32 channels, two Terminal
Panels are required to make connections to all channels of the E1476A
multiplexer. The Bank A channels (00-31) connect to channels 0-31 on the
first Terminal Panel and the Bank B channels (32-63) connect to channels
32-63 (shown in parentheses) of the second Terminal Panel. Figure 1-16
shows channel numbering for the E1586A Rack Mount Terminal Panel.

Analog Bus Connections
The Terminal Panel also provides Analog Bus connections to the multiplexer
module. However, since the terminal module is used with other modules,
the Analog Bus connections are labeled differently on the Terminal Panel.
Figure 1-16 shows the Analog Bus connections to the Terminal Panel.
Reference Thermistor
The E1586 Terminal Panel's three thermistors are located next to the
Connections and
channel 3 terminal block, between channels 11 and 16 and next to channel
Operations
24 (see Figure 1-16).
The thermistor excitation source is usually supplied by an externally
connected multimeter or voltmeter, such as the E1326/E1411 multimeter.
When using an E1326/E1411, the excitation is available on the Terminal
Panel terminals labeled HI-I and LO-I. The E1326/E1411 generates this
excitation using the 2-wire or 4-wire Ohms measurement functions.
