Description
Product Introduction
Applied Materials 0190-27952 is consistently identified by multiple secondary-market and repair sources as a Digi ConnectPort TS 16 terminal server, with Digi/AMAT identifier 50001344-01. J316Gallery directly lists the unit as “ConnectPort TS 16,” while another semiconductor-equipment inventory source identifies it as 50001344-01 ConnectPort TS 16, AMAT 0190-27952.
The engineering function is therefore communications-oriented rather than process control or wafer handling. A terminal server provides a bridge between serial equipment interfaces and an Ethernet network, allowing legacy serial devices to be accessed through network infrastructure.
This is an important distinction for spare-parts procurement. A terminal server should not be confused with a PLC CPU, I/O board, motion controller, or semiconductor process component.
Identification and Part-Number Cross-Reference
The most useful identifiers are:
- AMAT: 0190-27952
- Digi / associated P/N: 50001344-01
- Model: ConnectPort TS 16
- Equipment category: Terminal server / serial communications device
A direct J316Gallery listing gives the combination “ConnectPort TS 16 … P/N (1P) 50001344-01 0190-27952.”
A separate semiconductor-equipment inventory listing also identifies 50001344-01 as a ConnectPort TS 16 and associates it with AMAT 0190-27952.
There is also evidence for the related 0190-27952-04 designation. Semiconductor-equipment inventories identify that variant as ConnectPort TS 16, while current used-equipment listings describe 0190-27952-04 as an Applied Materials terminal server.

Specification Integrity Warning
The identification of the ConnectPort TS 16 is well supported. However, I would not publish detailed electrical specifications such as exact Ethernet speed, serial voltage levels, connector pinouts, power-input range, serial protocol support, or firmware version as guaranteed AMAT specifications unless they are confirmed from the exact Digi hardware revision.
One reseller describes the unit as supporting RS-232/RS-422/RS-485, 10/100 Ethernet, Telnet, SSH, and serial tunneling. Those are plausible ConnectPort TS 16 capabilities, but they should be treated as model-level secondary-source information, not necessarily as the complete specification of every AMAT-configured 0190-27952 unit.

What the 0190-27952 Does
The terminal server’s purpose is to provide network access to serial-connected equipment.
A simplified architecture is:
AMAT equipment controller → Ethernet network → ConnectPort TS 16 → serial ports → legacy serial devices
This arrangement is particularly useful when equipment contains older serial instruments or controllers that must communicate with a newer networked supervisory system.
The terminal server itself does not perform the same role as a PLC CPU. It primarily transports communications between network and serial interfaces.
Field Application
In a semiconductor equipment environment, the 0190-27952 can be relevant when multiple serial devices need centralized network access.
Typical connected equipment may include:
- Legacy serial controllers
- Instrumentation
- Auxiliary equipment interfaces
- Equipment-management interfaces
- Older motion or process subsystems
- Maintenance/service interfaces
The exact device connected to each serial port is configuration-dependent.
That means replacing a failed terminal server is not simply a matter of confirming that the Ethernet link comes up. The individual serial channels must communicate correctly with the equipment connected to them.
Troubleshooting Procedure
1. Check the Network Side First
Before replacing the terminal server, verify:
- Ethernet link status
- Network cable
- Switch port
- IP configuration
- Network reachability
- Equipment-controller communication
- Any network segmentation or routing changes
A network-side failure can easily be mistaken for a terminal-server failure.
2. Check the Serial Side
If Ethernet communication is normal but one device is unreachable, inspect:
- Individual serial cable
- Connector condition
- Port assignment
- Serial device power
- Device address/configuration
- Baud rate and framing configuration
- Flow-control settings where applicable
If only one serial device is offline, the terminal server itself should not automatically be condemned.
3. Check for Multi-Port Failure
A particularly useful diagnostic clue is the number of affected channels.
One serial device failed:
Investigate that serial path first.
Several serial devices failed simultaneously:
Investigate the terminal server, network connection, power, configuration, or upstream equipment controller.
All communications failed:
Check power, Ethernet connectivity, system configuration, and the terminal server as a complete unit.
Incoming QA / Test SOP
For a replacement 0190-27952, record the following before putting it into production inventory:
| Inspection | Acceptance Criteria |
|---|---|
| AMAT P/N | 0190-27952 clearly identified |
| Digi model | ConnectPort TS 16 |
| Associated P/N | 50001344-01 where applicable |
| Variant | Check whether installed unit is 0190-27952 or 0190-27952-04 |
| Housing | No major damage or deformation |
| Connectors | No bent, broken, or heavily corroded contacts |
| Ethernet interface | Link established during functional test |
| Serial ports | Test representative/all required channels |
| Configuration | Compare with the installed unit |
| Firmware | Record version if accessible |
| Network settings | Document before deployment |
| Condition | New Surplus / Used Tested / Refurbished / Untested |
| Warranty | Obtain written terms |
A terminal server that merely powers up should not automatically be classified as tested.
The strongest spare is one that has been tested for both Ethernet communication and the required serial channels.
⚠️ Veteran’s Tech Trap Guide
Trap 1 — Confusing 0190-27952 with an Electrostatic Chuck
Some online pages currently describe 0190-27952 as a semiconductor-process electrostatic chuck. That description conflicts with several direct listings that identify the exact part number as a ConnectPort TS 16 terminal server.
For procurement purposes, the terminal-server identification has substantially stronger cross-source support.
Trap 2 — Ignoring the “-04” Variant
Do not automatically assume:
0190-27952 = 0190-27952-04
They are closely related identifiers, but the installed equipment documentation should determine whether the suffix is significant.
Current semiconductor-equipment listings specifically identify 0190-27952-04 as ConnectPort TS 16.
Trap 3 — Buying by Model Alone
“ConnectPort TS 16” is not sufficient for a high-criticality AMAT spare.
Use the complete chain:
AMAT P/N → Digi P/N → hardware revision → installed configuration.
Trap 4 — Treating a Working Ethernet Port as a Full Functional Test
The device can establish an Ethernet link while one or more serial channels remain defective or incorrectly configured.
For production-critical inventory, test the actual communication path required by the tool.
Spare-Inventory Strategy
The 0190-27952 should be classified according to the number of AMAT tools that depend on the communications path.
For a single critical legacy tool, a practical strategy is:
- One installed unit
- One tested spare
- One repair candidate only if repair capability exists
For multiple tools using the same configuration, first establish actual interchangeability before pooling inventory.
The key inventory fields should include:
- AMAT part number
- Digi part number
- Variant/suffix
- Hardware revision
- Firmware version
- Serial number
- Tool compatibility
- Test status
- Date tested
- Warranty expiration
This prevents a common failure in legacy-equipment inventory: having a box labeled “ConnectPort TS 16” that cannot be confidently assigned to the production tool.
New Surplus vs. Used vs. Refurbished
New Surplus
Preferred when genuine and correctly stored. Verify the AMAT label and associated Digi identifier.
Used Tested
A reasonable option for legacy equipment if the supplier provides meaningful functional-test evidence.
One secondary-market listing identifies an AMAT 0190-27952 / 50001344-01 unit as Used Working and states a 90-day warranty.
Refurbished
Ask what was actually performed:
- Cleaning?
- Component replacement?
- Connector replacement?
- Firmware verification?
- Full serial-port test?
- Ethernet test?
“Refurbished” without a test report is not a sufficiently precise technical condition.
Untested / As-Is
Treat as a repair candidate rather than a production-ready spare.
J316Gallery currently lists an 0190-27952 unit as pre-owned and explicitly states that the unit is untested, sold as-is, and without warranty.
