Precautions
Important Safety Warnings
[Power]
Caution
Operate unit only at the specified supply voltage.
Disconnect the power cord via the power plug only. Do not pull on the cable portion.
Stop
Do not place or drop heavy or sharp-edged objects on the power cord. A damaged
cord can cause fire or electrical shock hazards. Regularly check the power cord for
excessive wear or damage to avoid possible fire / electrical hazards.
Caution
Ensure the power cord is firmly plugged into the AC outlet.
[Grounding]
Caution
Ensure the unit is properly grounded at all times to prevent electrical shock.
Hazard
Do not ground the unit to gas lines, units, or fixtures of an explosive or dangerous
nature.
[Operation]
Hazard
Do not operate the unit under hazardous or potentially explosive atmospheric
conditions. Doing so could result in fire, explosion, or other hazardous results.
Hazard
Do not allow liquids, metal pieces, or other foreign materials to enter the unit. Doing
so could result in fire, other hazards, or a unit malfunction.
If a foreign material does enter the unit, turn the power off and immediately disconnect
the power cord. Remove the material and contact an authorized service representative
if damage has occurred.
[Transportation]
Hazard
Handle with care to avoid impact shock during transit, which may cause malfunction.
When you need to transport the unit, use the original or suitable alternative packing
material.

3
[Circuitry Access]
Do not remove covers, panels, casing, or access the circuitry with power applied to
the unit. Turn the power off and disconnect the power cord prior to removal. Internal
servicing / adjustment of unit should only be performed by qualified personnel.
Stop
Do not touch any parts / circuitry with a high heat factor.
Capacitors can retain enough electric charge to cause mild to serious shock, even after
the power has been disconnected. Capacitors associated with the power supply are
especially hazardous.
Hazard
Unit should not be operated or stored with cover, panels, and / or casing removed.
Operating the unit with circuitry exposed could result in electric shock / fire hazards or
a unit malfunction.
[Potential Hazards]
Caution
If abnormal odors or noises are noticed coming from the unit, immediately turn the
power off and disconnect the power cord to avoid potentially hazardous conditions. If
problems similar to the above occur, contact an authorized service representative
before attempting to operate the unit again.
[Rack Mount Brackets, Ground Terminal, and Rubber Feet]
Caution
To rack-mount or ground the unit, or to install rubber feet, do not use screws or
materials other than those supplied. Doing so may cause damage to the internal
circuits or components of the unit. If you remove the rubber feet that are attached to
the unit, do not reinsert the screws that secure the rubber feet.
[Consumables]
Caution
Consumable items that are used in the unit must be periodically replaced. For further
details on which parts are consumables and when they should be replaced, refer to
the specifications at the end of the Operation Manual. Since the service life of the
consumables varies greatly depending on the environment in which they are used,
such items should be replaced at an early date. For details on replacing consumable
items, contact your dealer.

4. Setup Menu
Network settings such as IP address setting can be changed in the Setup menu. Prepare a PC to
connect to the HVS-GPIO128 via LAN or RS-232C. Use a terminal software (such as Tera Term) to
communicate with HVS-GPIO128.
4-1. If Connecting via LAN
(1) Change the PC IP address to 192.168.0.10 (Netmask: 255.255.255.0).
(2) Connect the PC and HVS-GPIO128 using LAN.
(3)Launch a terminal software on the PC
(4)Specify 192.168.0.40 (IP address of HVS-GPIO128) to connect to the HVS-GPIO128.
4-2. If Connecting via RS-232C
(1) Use an RS-232C cable to connect the PC to the SERVICE port on the HVS-GPIO128.
(2) RS-232C communication specifications of the HVS-GPIO128 are as shown below.
