Section 1 - Introduction
General
The Network Terminal is used in multiple On-Board pump installations to
provide control of up to 20 pumps from a single point. The Terminal has a
built-in keypad and display that allows monitoring and control of any
pump on the network. The Network Terminal is available in two different
configurations; half panel and right hand panel as shown in Figure 1-1.
The Network Terminal can be connected to a host computer through the
Host RS-232 serial port so that the host can also address any pump on the
network. The Network Terminal also coordinates the use of roughing
valves in a specified group of pumps. This prevents cross contamination of
the pumps through the roughing lines during regeneration. On-Board
Pumps can be mapped together and the roughing valves in that map are
controlled through a token pass protocol. The Network Terminal allows
you to initiate regenerations simultaneously to two or more pumps. Refer
to Section 4 - Operation for more information.
NOTE: All personnel with installation and operation responsibilities
should become familiar with the contents of this manual to ensure high
quality, safe, and reliable Network Terminal performance.
On-Board NetLink Option
The Network Terminal can be connected to an On-Board NetLink
that allows On-Board Central Control (OCC) for Windows software to
communicate with multiple Network Terminals.
NOTE: The Network Terminal must either have the communication ports
or be upgraded to communicate with the On-Board NetLink. Refer to the
On-Board NetLink Installation, Operation, and Maintenance manual
CTI-CRYOGENICS P/N 8040390 for more information.

any damage to the shipping company at once. Retain the shipping cartons
for storage or return shipment.
Inspect the Network Terminal for damage by examining the overall
exterior, keypad, electrical connectors, ON/OFF switch, and the power
cable for damage.

Section 3 - Installation
Network Configurations
As many as twenty On-Board Cryopumps can be connected to the Network
Terminal. The pumps are networked together using CTI-CRYOGENICS
network cables. Before connecting the pumps together, set the address
switch on each pump so that each pump has its own number from 0-9.
The network cables are run from pump to pump, daisy chained together as
shown in Figure 3-1. The first connection is made to the Pumps 00-09
connector for pumps 00-09 on the rear panel of the Network Terminal. The
pumps need not be connected in sequential numerical order (i.e., you may
connect the pumps as follows: 01, 03, 06, 02, 04, etc.). Pumps numbered
10-19 must be connected to the Pumps 10-19 connector identified in Figure
3-1. The address switches on the pump modules, as shown in Figure 3-2,
shall be set to 00-09 respectively but will be recognized by the Network
Terminal as pumps 10-19 as shown in Figure 3-1.
The total network chain shall not exceed 1,000 feet. This means that the
cable distance from the Network Terminal to the last module could be
connected with three 300 foot cables for a total network chain of 900 feet.
Terminators are required to ensure proper data communication between the
pump modules and the Network Terminal. The last module on the network
chain must have a terminator attached to the unused network connector as
shown in Figure 3-1 for proper placement. Two terminators are supplied
with the unit so that a terminator may be placed at the end of each of the
two network chains.

Power Connections
The Network Terminal is shipped from the factory set to the 110/120 VAC
setting. The input power connector will have to be modified if you plan to
operate the Network Terminal at 220/240 VAC. Follow the appropriate
procedure for your specific operating voltage.
NOTE: The Network Terminal is fused for both 110/120 and 220/240 VAC
operation. Use either size 3AG or 5 x 20mm 0.25 amp fuses when
replacing the fuse.
110/120 VAC
1. Insert the provided power cable plug into the receptacle on the
rear panel of the Network Terminal.
2. Insert the opposite end of the power cable into 110/120 VAC power
receptacle.
NOTE: The bonding stud, as shown in Figure 3-1, is intended for
applications where Electromagnetic Interference (EMI) may be a problem.
It is not to be used as a protective ground. Attach a ground using accepted
EMI grounding practices.
3. If desired, connect an EMI ground conductor to the ground stud.
4. Set the power switch to the ON position.

1. Modify the input power connector as follows:
a. Place a small flat head screwdriver in the slot above the
lettering and twist out the fuse holder module as shown in
Figure 3-3.
Figure 3-3: Input Power Connector 220/240 VAC Modification
b. Rotate the module 180ºand insert the module into the input
power connector as shown in Figure 3-3.
c. Make sure the 220/240 VAC designation aligns with the
white arrow as shown in Figure 3-3.
NOTE: The provided power cable will have to be modified, or a new cable
will have to be purchased, to provide 220/240 VAC power to the
Network Terminal. The power connector on the rear panel of the Network
Terminal is a standard IEC 320 power connector.
2. If modification is necessary, perform the following steps:
a. Cut the plug off the end of the power cord which connects to
the power source.
b. Connect an appropriate 220/240 VAC plug to the power
cable.
