1. Introduction
The STM-60XC series Modbus gateways are bi-directional gateways for integrating new and existing
Modbus/RTU and Modbus/ASCII serial devices to newer TCP/IP networked-based devices. The STM-
601C/602C/604C feature two independent Ethernet ports and MAC addresses to provide redundancy
and reliability. They provide a simple and cost-effective way to bring remote management and data
accessibility to thousands of devices that cannot connect to a network. STM-601C/602C/604C provide
a feature that can allow users to select either master or slave operation mode for each serial port.
They not only allow an Ethernet master to control serial slaves, but also allow serial masters to control
Ethernet slaves.
1.1 Product Overview
Antaira’s STM-60XC series of Modbus Gateways are a robust, feature-rich, and cost-effective way to
integrate Ethernet and Serial Modbus devices. The STM-60XC series provides one, two, or four serial
ports, two Ethernet ports, a wide range of power inputs, and a compact slim design, making them an
ideal solution for connecting multiple Modbus/RTU and Modbus/ASCII serial devices to Modbus TCP
(Ethernet).
Originally developed for PLCs in industrial automation and manufacturing control applications,
Modbus is one of the most popular open standard protocols in use today. The communication mode
can be Modbus RTU/ASCII (Serial) or Modbus TCP (Ethernet). Many industrial devices use Modbus
as their communication standard. However, the Ethernet-based Modbus protocol is different from the
original serial-based protocols in that a Modbus Gateway is needed to be a bridge for integration.
The two Ethernet ports allow the STM-60XC series to establish two separated Ethernet connections
to two Ethernet domains or two Ethernet switches in the same domain. Through a dual Ethernet
connection, the STM-60X series greatly improves the device connectivity reliability, increases system
stability, and simplifies the redundant configuration.
The Modbus/RTU and Modbus/ASCII protocols define how a “master” device pulls one or more
“slave” devices and writes real-time data over RS-232, RS-422, or RS-485 serial data communication.
The STM-60XC series provides a feature that can allow users to select either master or slave
operation for each serial port. The STM-60XC series not only allows Ethernet masters to control serial
slaves, but also allow serial masters to control Ethernet or serial slaves. Furthermore, the STM-60XC
series can allow both Ethernet and serial slaves to be controlled by both Ethernet and serial masters.
The STM-60XC series supports various operating modes: RTU Master, RTU Slave, ASCII Master,
and ASCII Slave

Warning! Power down and disconnect the power cord before servicing or wiring the serial
device server.
Caution! Do not disconnect modules or cabling unless the power is first switched off.
The device only supports the voltage outlined in the type plate. Do not use any other power
components except those specifically designated for the serial device server.
Caution! Disconnect the power cord before installation or cable wiring.
The STM-60XC series supports dual 12 to 48 VDC power inputs and power-fail relay output.
The following figure, Figure 2.8, illustrates a P-Fail alarm application example. The P-Fail alarm
contacts are visible on the front view of the terminal block.

3. Mounting Installation
3.1 DIN-Rail Mounting
The DIN-Rail mount option is the quickest installation option. Additionally, it optimizes the use of rail
space. The metal DIN-Rail kit is secured to the rear of the serial device server. The device can be
mounted onto a standard 35mm (1.37”) x 75mm (3”) height DIN-Rail. The devices can be mounted
vertically or horizontally. Refer to the following guidelines for further information.
Installing the DIN-Rail Mounting Kit
1. Insert the top back of the mounting bracket over the DIN-Rail.
2. Push the bottom of the server towards the DIN-Rail until it snaps into place.
Removing the DIN-Rail Mounting Kit
1. Push the server down to free the bottom of the plate from the DIN-Rail.
2. Rotate the bottom of the device towards you and away from the DIN-Rail.
3. Once the bottom is clear of the DIN-Rail, lift the device straight up to unhook it from
the DIN-Rail.
3.2 Wall Mounting
The wall mounting option provides better shock and vibration resistance than the DIN rail
vertical mount.
Note! When installing, make sure to allow for enough space to properly install the
cabling.
Before the device can be mounted on a wall, you will need to remove the DIN-Rail
plate.
1. Rotate the device to the rear side and locate the DIN mounting plate.
2. Remove the screws securing the DIN mounting plate to the rear panel of the
server.
3. Remove the DIN mounting plate. Store the DIN mounting plate and provided

screws for later use.
4. Align the wall mounting plates on the rear side. The screw holes on the device and
the mounting plates must be aligned, see the following illustration Figure 3.3.
5. Secure the wall mount plates with M3 screws, see the following figure.
Figure 3.3
Installing Wall Mount Plates
Once the wall mounting plates are secure on the device, you will need to attach the wall screws (x8).
6. Locate the installation site and place the server against the wall, making sure it is the
final installation location.
7. Use the wall mount plates as a guide to mark the locations of the screw holes.
8. Drill four holes over the four marked locations on the wall, keeping in mind that the
holes must accommodate wall sinks in addition to the screws.
9. Insert the wall sinks into the walls.
10. To mount the wall plate, use screws of the size shown in the following illustration.
Figure 3.4
Wall Mounting Screw Dimensions
11. Align the wall mount plate over the screws on the wall.
12. Install the wall mount plate on the screws and slide it forward to lock in place, see the
following figure –Figure 3.5.
Note!
Make sure the screws’dimensionsare suitable for use with the wall
mounting plate.
Do not completely tighten the screws into the wall. A final adjustment may
be neededbefore fully securing the wall mounting plates on the wall.

5. Maintenance and Service
• If the device requires servicing of any kind, the user is required to disconnect and remove it
from its mounting. The initial installation should be done in a way that makes this as
convenient as possible.
• Voltage/power lines should be properly insulated as well as other cables. Be careful when
handling them so as to not trip over.
• Do not under any circumstance insert foreign objects of any kind into the heat dissipation
holes located in the different faces of the device. This may not only harm the internal layout,
but might cause harm to user as well.
• Do not under any circumstance open the device for any reason. Please contact your dealer
for any repair needed or follow the instructions within the manual.
• Clean the device with dry soft cloth.
