CH Tech EM405D user manual Recommendation, Default subnet mask is Gateway

Page 18

RECOMMENDATION

The EM405D is an embedded device without an input device or display that can be used to determine the current configuration of the device. This can cause difficulties in determining at what IP address to access the module. For this reason, it is highly recommended, but not required, that the EM405D be configured to use a static IP address.

4.2.2 Subnet Mask

The subnet mask defines the number of bits that are taken from the IP address to refer to the given network subsection. The subnet mask allows Ethernet based networks to be separated into various subnets. The EM405D should be in the same subnet as the controlling PC.

The default subnet mask is: 255.255.255.0

4.2.3 Gateway

The gateway address allows the EM405D to communicate with other network segments. If communication outside of the given network segment is necessary, the gateway address should be set to the IP address of the router connecting the local network segment to the outside world. The gateway address, if needed, must be within the local network.

The default gateway address is: 0.0.0.0

4.2.4 Port Numbers

Every TCP connection to the device is defined by a destination IP address and a port number. The port number must be known by the software to communicate with the module. The port number is configurable but it is rarely, if ever, necessary to change it from its default setting. Port 9999 is reserved for Telnet access to the EM405D’s configuration utility.

The default port number for standard module access is: 10001

4.2.5 Wireless Settings

Wireless EM405D’s have other settings that must be configured for the carrier to work on a wireless network.

Network Mode: A wireless network can operate in one of two modes, infrastructure or ad-hoc. In infrastructure mode, all wireless network traffic passes through an access point. An access point can be a bridge, a router, or a combination bridge + router device. The access point may handle data encryption, bridging to wired networks, assigning IP addresses via DHCP, or a host
