What's the difference between the DSE 7420 and 7320?

The 7420 MkII adds native Ethernet connectivity: embedded web server, Modbus TCP, and SNMP v2c — none of which exist on the 7320. The 7320 has only RS232/RS485/USB for communication. Choose the 7420 when the generator needs to integrate with a building management system (BMS) over the facility's IP network.

Does the 7420 support paralleling?

No — the 7420 is a single-genset auto mains failure controller. For paralleling, you need the DSE 8610 MkII (genset side) + DSE 8660 MkII (mains side). The 7420 is designed for standalone standby generators that start on mains failure and transfer load via an ATS.

What is SNMP and why does it matter for generators?

SNMP (Simple Network Management Protocol) allows the generator controller to be monitored by the same IT tools used for network equipment (Nagios, PRTG, SolarWinds). In data centers, this means the generator appears alongside servers, switches, and UPS in a unified monitoring dashboard — rather than requiring a separate generator-specific monitoring system.

Can the 7420 be monitored remotely without DSEWebNet?

Yes — the embedded web server provides a browser-based interface accessible from any device on the same network. SNMP sends alerts to any SNMP manager. Modbus TCP integrates with any SCADA system. DSEWebNet (cloud) is an additional option but not required for remote visibility.

Overview#

The DSE 7420 MkII is a networked auto mains failure (AMF) generator controller — the "connected" evolution of the DSE 7320. While the 7320 is the industry workhorse for standalone standby, the 7420 adds native Ethernet with embedded web server, Modbus TCP, and SNMP v2c — making it the standard for generators that need to integrate directly with building management systems over IP networks.

In data centers, hospitals, and modern commercial buildings where everything connects to the BMS, the 7420 eliminates the need for external protocol gateways or add-on communication modules.

7420 vs 7320: when to choose which#

Feature	DSE 7320	DSE 7420 MkII
Serial (RS232/RS485)	✅	✅
USB	✅	✅
Ethernet	❌	✅
Modbus TCP	❌	✅
SNMP v2c	❌	✅
Embedded web server	❌	✅
Price	Lower	Higher
Use case	Simple standby	BMS-integrated standby

Choose 7320 when: standalone operation, no network integration needed, cost-sensitive. Choose 7420 when: BMS integration required, IT monitoring tools (SNMP), remote web-based diagnostics.

BMS integration scenarios#

The 7420's native protocols cover every common BMS integration:

Modbus TCP → Niagara/Tridium, Schneider EcoStruxure, Honeywell Niagara
SNMP → Nagios, PRTG, SolarWinds, Zabbix (data center IT tools)
Web server → Direct browser access for facility managers
DSEWebNet → Cloud monitoring with SMS/email alerts (via DSE890 gateway)

Our service experience#

The 7420 MkII is our standard recommendation for new commercial standby installations where the facility has a BMS. The embedded web server is invaluable for remote diagnostics — we can check controller status, read fault codes, and verify exercise history from our office before dispatching a technician. This reduces unnecessary site visits and speeds up troubleshooting. Configuration is done via DSE Configuration Suite (same software as the 7320 — no separate training needed).
