Page 4: Maintenance
Installation consists of mounting the device, connecting to an IP network, connecting inputs and outputs, providing power and configuring via a web browser. TCW122B-WD can be wall or flat, not flammable surface mounted, in a clean and dry location room. Ventilation is recommended for installations where ambient air temperature is expected to be high. - Page 5 The controller supports one active session – only one user can operate the device. If another user tries to login, the message “Someone’s logged in” appears: The active session will be terminated automatically, if the current user stays inactive for 2 minutes. 11.2 Monitoring page After successful authorization, the “Monitoring”...

Page 9: Application Examples
12.1 Watchdog TCW122B-WD device is set to send periodic ping to AP (Local network) and remote server (Internet). If there is no answer in “Ping time out for restart”, the corresponding relay is activated in order to reset particular network equipment. - Page 10 We guarantee proper operation only with our 1-Wire sensors series TST1XX and TSH2XX. 14. Control and monitoring using SNMP TCW122B-WD can be configured and monitored through SNMP (Simple Network Management Protocol). This could be done using every SNMP v.1 compatible program. Parameters that can be changed, are grouped according to their functions in the tables below.
