The Virtual Access GW2020P Series industrial M2M router is designed for use in outdoor equipment and cabinets at roadsides, substations and remote telemetry locations. Applications include SCADA, Telemetry, security, emergency services and other critical infrastructure. The GW2020P Series can be automatically provisioned over an IP network with a minimum of effort using the Virtual Access Activator auto provisioning server. This enables the unit to be deployed without requiring any configuration by installers.
The GW2020P Series is a weather-proofed, ruggedised router suitable for high isolation scenarios such as electrical transformation centres, substations and outdoor cabinets. It is DIN Rail or wall mountable.
The GW2020P Series offers two Ethernet ports and supports GPRS, 3G, LTE and optionally, 450MHz CDMA. It offers secure WAN connectivity for internet and private networking environments over wireless broadband paths.

Dual SIM
The GW2020P Series router incorporates the latest wireless technology. Dual SIM architecture ensures that a backup 3G/LTE network can take over should the primary network fail. The router detects a network problem and fails over to a standby SIM/ APN if necessary, ensuring customers’ SLAs are upheld. The GW2020P Series 3G/LTE functions also include support for inbound and outbound SMS, so for instance, if all other WAN services are unavailable, commands can be sent to the router to perform diagnostics or even reset function.

Environmentally Hardened
The GW2020P Series router is designed to meet the IP33 standard for ingress protection and EN standards for harsh environments such as electric power, rail and roads.

Ingress protection
To protect against rain and dust, the box is completely sealed other than the bottom connectors.

External vibration
The device is designed to withstand environments such as roadsides where there is a high level of vibration.

The GW2020P Series is tested to random vibration, drop, topple and bump standards to ensure the device will continue to operate under conditions that would not be tolerated by commercial grade communications products. It has an optional conformal coating that protects against condensation.

EMC immunity, Safety, ESD and Electrical Isolation
Environments such as substations and transport can contain high levels of radiated emissions from switchgear, tracks and other power sources. In addition there are tight safety regulations to prevent injury or equipment damage. These require far higher levels of isolation than commercial grade communications equipment. The device is designed to meet the high EMC, safety, ESD and isolation standards mandated by these applications. The PVC enclosure enables the GW2020P Series to be electrically isolated from ground, providing a high level of immunity from electrical surges and transients.

In addition, the RS232 and RS485 serial ports on the GW2024P are fully isolated from the main circuit to a level of 2000V DC continuous. This provides a high level of reliability in harsh electrical environments.

Automatic Failover
Optional automatic failover from fixed to wireless circuits ensures business connectivity through network or last mile circuit outages, whilst email alerting and auto-failback confirm primary circuit restoration.

Two Port 10/100 Mbps Managed Ethernet Switch
The two port 10/100 Mbps managed Ethernet switch enables multiple devices to be connected in remote environments with the ability to segment into individually filtered subnets or DMZs. Tagged VLAN (802.1q) segmentation offers further versatility for diverse network applications.
