Reference Voltage Output Connectors
The black connector outputs the same vortage as the chassis
and the red connector output ＋1 V ±0.2%. The output
resistance is 200Ω, and these are used for preamplifier sensi-
tivity calibration.
⑤
Input Connectors
These input connectors are connected directly to their
corresponting channel preamplifier inputs. the black G con-
nectors are guard connectors, the red (−) terminal is a floating
ground, and the red (＋) terminal is the signal positive-side
input terminal. The accessory input cables can be connected
here.

Shorting Bar
The black G and red (−) terminals are connected to a metal
fixture, and this operation is explained below.
⑦
Printing External Input Connector (Option)
This is used for input of character signals from an external
keyboard to control the printer. See Secting 4 below for details
on the terminal strip.
⑧
External Control Signal Connector
This is used for input of external signals to control paper feed,
pen heating, markers, and other operations. See Section 4 for
details.
