Moxa NPort 5610-8 8-Port RS-232 Rackmount Serial Device Server

What the NPort 5610-8 gives a serial instrument

An eight-port RS-232 device server in a 19-inch rackmount case with RJ45 serial connectors and an LCM display. Moxa’s own one-line description of the NPort 5610-8 reads: 8-port RS-232 rackmount device server with RJ45 connectors and 100 to 240 VAC power input.

From the manufacturer’s specification table, the power input is 100 to 240 VAC, 47 to 63 Hz; operating temperature is 0 to 60°C (32 to 140°F); dimensions are 480 x 45.5 x 198.25 mm (18.90 x 1.79 x 7.80 in); weight is 2,290 g (5.05 lb).

Standards and approvals printed for this model include safety standard UL 62368-1. Approvals can differ between variants of a series, so check the one on the exact order code.

Technical specifications

Where it fits and what to check

It is used in control rooms and server racks to centralise serial consoles, RTUs and legacy instruments on the plant LAN.

On the practical side, mounting is listed as 19-inch rack mounting; the housing is metal; the stated MTBF is 903,009 hrs; the warranty period is 5 years. Treat the MTBF as a manufacturer prediction under its stated method, not a guarantee for your site.

What to confirm before ordering: the AC or DC power option and the 8-port versus 16-port model in the same series. Our team in Muscat works from the exact code on your enquiry, as an independent supplier.

The Moxa product list shows these models in the same family page (16 entries): NPort 5610-16, NPort 5610-16-48V, NPort 5610-8, NPort 5610-8-48V, NPort 5630-16, NPort 5630-8, NPort 5650-16, NPort 5650-16-HV-T, NPort 5650-16-M-SC, NPort 5650-16-S-SC, NPort 5650-16-T, NPort 5650-8, NPort 5650-8-HV-T, NPort 5650-8-M-SC, NPort 5650-8-S-SC, NPort 5650-8-T. Suffixes such as -T generally mark wide-temperature versions and fiber suffixes (M, S, MM, SS with SC or ST) mark the connector and fiber type, but the order code printed on the datasheet governs.

Typical applications for an eight-port RS-232 device server

The NPort 5610-8 brings serial devices onto an Ethernet network so they can be reached from a control room or server room rather than through local cables. Typical uses include connecting legacy instruments, analysers, weighing indicators, RTUs and serial consoles of network and server equipment to the plant LAN. Because it is a rackmount unit, it fits naturally in communication cabinets and server racks, where several serial devices can be gathered in one place and managed together.

The Real COM operation mode lets existing software that expects a local COM port communicate with the remote device over the network, which is often the simplest way to keep older SCADA or data collection software running when equipment is moved or the cabling is changed. TCP server and client modes and the pair connection mode cover cases where devices exchange data directly over the network.

Selection and integration points

Confirm that every device to be connected uses RS-232, as this model is the RS-232 version of the series, and check that the required baudrates, data bits, parity and flow control settings appear in the specification table. Count the serial devices and decide whether the eight-port or sixteen-port model in the same series is the better fit, leaving some spare capacity. Check the power arrangement in the cabinet, since this order code takes AC input and the family also includes other power options.

Agree with the IT or OT network team how the unit will be addressed and managed. The management protocols listed include SNMP, and the security protocols include HTTPS and SNMPv3, so the device can be brought into the existing network management and security policy. Plan the serial wiring from each device to the RJ45 serial connectors, and document the pin assignment used for each instrument.

Installation practice and site conditions in Oman

Mount the unit in a 19-inch rack with adequate ventilation, and keep it within the operating temperature and humidity range listed above. In Oman and the GCC, communication rooms on industrial sites can become hot when air conditioning fails, so install the unit where airflow is good and include room temperature in the site monitoring. Dust from desert sites can also build up inside racks, so keep cabinet doors closed and keep the communication room clean.

Label every serial cable with the device and channel it serves, route serial cables away from power cables, and keep a record of the configuration so that it can be restored quickly after maintenance.
