3. Check and Install Hardware

Depending on your order, your ChartScan unit may not require all the steps under this heading. If a
step does not apply to your unit, simply go on to the next one.
a) Verify Voltage Setting
Based on your order, your ChartScan system was set at the voltage indicated on the sticker (located on
the rear of the unit, near the power switch). Verify that the voltage value indicated on the sticker
matches the voltage of your intended AC power supply. If you need to change the voltage selection for
any reason, refer to Chapter 3, Power Aspects, Changing the Voltage Setting.
b) Verify DIP Switch Setting
The DIP switch is located on the lower right corner of ChartScan's rear panel. Default settings are
indicated in the following figures and table. Refer to Chapter 3 if you desire to change the RS-232
parameters from their default values, or if you wish to use the IEEE 488 interface option. For ethernet
use of ChartScan, make sure the unit is configured for RS-232 serial communications, then refer to the
Net232 User's Guide (p/n 1037-0901).

c) Install Signal Conditioning Card(s)
Signal conditioning cards are pre-installed per customer order. However, if you need to install a signal
conditioning card, or CSN/Relay card, perform the following steps. Repeat the steps for additional
cards, and for placing cards into the optional CSN/Exp expansion chassis, if applicable.
Ensure ChartScan is powered down and not connected to any power source prior to
installing or removing a card. Failure to do so could cause equipment damage.
