Wall Mounting
For some applications, it may be more convenient to mount the TAP-M310R Series to a wall.
NOTE Wall mounting is only supported for TAP-M310R-NPS-1R and TAP-M310R-NPS-1P1R models.
STEP 1: If installed, remove the DIN-rail attachment plate from the device first. Attach the wall-mounting plates using the six M3x8mm screws included in the wall mounting kit.
STEP 2: Mounting the TAP-M310R Series to a wall requires 4 screws. Use the device with the wall-mounting plates attached as a guide to mark the location of the 4 screws on the wall. The heads of the screws should be between 5.5 mm and 8.5 mm in diameter. The screw shank should be between 2.4 to 3.98 mm in diameter. The screw length should be at least 15.0 mm, as shown in the figure on the right.
ATTENTION
Test the screw head and shank size by inserting the screws into one of the keyhole shaped apertures of the wall-mounting plates before attaching the plates to the wall.
STEP 3: Drill the holes into the wall on the marked locations, leaving about 2 mm of space between the bottom side of the screw head and the wall to allow room for sliding the wall-mounting kit between the wall and the screws.
STEP 4: Once the screws are fixed into the wall, insert the four screw heads through the large opening of the keyhole-shaped apertures of the mounting kit, and then slide the TAP device downwards. Tighten the four screws for added stability.
Wiring Requirements
WARNING
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your Moxa TAP-M310R.
Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes dictating the maximum current allowable for each wire size. If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to your equipment.
Read and Follow These Guidelines:
- Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must cross, make sure the wires are perpendicular at the crossing point.
- Do not run signal or communications wiring and power wiring through the same wire conduit. To avoid interference, wires with different signal characteristics should be routed separately.
- You can use the type of signal transmitted through a wire to determine which wires should be kept separate. The rule of thumb is that wiring that shares similar electrical characteristics can be bundled together.
- Keep input wiring and output wiring separated.
- For future reference, you should label the wiring used for all of your devices.
Grounding the Moxa TAP-M310R
Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI). Run the ground connection from the ground screw to the grounding surface prior to connecting devices to the TAP-M310R device.
The TAP-M310R should be well-grounded to ensure safe operation. The grounding screw connection depends on the model configuration.
For models without a power module: Connect the grounding wire to the grounding screw located on the top panel of the radio module.
For models with a power module: Connect the grounding wire to the grounding screw located on the top panel of the power module.
- Grounding Screw
- Power Module
ATTENTION
This product is intended to be mounted to a well-grounded mounting surface, such as a metal panel. The potential difference between the two ground potentials must be zero. If the potential difference is NOT zero, the product could be permanently damaged.
Connecting the Power Inputs
The TAP-M310R Series supports multiple power input options to suit different needs. Connect to the appropriate power input based on your specific configuration.
ATTENTION
Before connecting the TAP-M310R Series to the power input, make sure the power source voltage is stable.
NOTE We recommend installing a power insulation device between the TAP-M310R Series and the power source to avoid damage from power surges.
STEP 1: Connect the power cord connector to the power input port.
STEP 2: Screw the support nuts on the power cord connector to ensure a tight connection.
The power input depends on the model used. Refer to the connector type and pinout overview for each model type below.

Communication Connections
10/100/1000(/2500)BaseT(X) Ethernet Ports
The TAP-M310R has one 10/100/1000/2500BaseT(X) Ethernet port (LAN1) on the front panel for connecting Ethernet-enabled devices. TAP-M310R-1P1R1S and -1P2R1S models have an additional two 10/100/1000BaseT(X) Ethernet ports (LAN4 and LAN5) on the front panel. The ports use M12 X-coded 8-pin female connectors. Most users configure these ports for Auto MDI/MDI-X mode, in which case the port’s pinouts are adjusted automatically depending on the type of Ethernet cable used (straight-through or cross-over), and the type of device (NIC-type or HUB/switch-type) connected to the port.
10/100/1000(/2500)BaseT(X) Port Pinouts
| Pin | 10/100 BaseT(X) | 1000/2500 BaseT(X) |

1000/2500BaseSFP Fiber Ports
The TAP-M310R-1P1R1S and -1P2R1S have two 1000/2500BaseSFP ports (LAN2/LAN3) on the front panel for installing SFP modules (the SFP modules must be purchased separately). To operate properly, a fiber transceiver must be used with each SFP module. Unlike electrical signals, optical signals do not require a circuit to transmit data. To transmit full-duplex optical signals between two devices (e.g., device 1 and device 2), you need to run two optical lines between the devices. One optical line is used to transmit data from device 1 to device 2, and the other optical line is used to transmit data from device 2 to device 1. Connect the Tx (transmit) port of device 1 to the Rx (receive) port of device 2, and the Rx port of device 1 to the Tx port of device 2.
LC-Port Pinouts
NOTE 1000/2500BaseSFP ports that are not in use should be covered with an IP67-rated plastic cap.
