Viewing Wrs And Rsx Default Values - Siemens Wireless Room Sensor Solution User Manual

a. Connect a computer cable (540-143) from a computer to the RJ-11 port on the bottom of the WRS.
The WRS wakes up and remains active for the amount of time specified by its HMI port timeout
setting (default = 5 minutes). If the WRS returns to sleep mode before you are done, disconnect
and then reconnect the cable to the WRS port.
b. Start a HyperTerminal session, log on (1200 baud, 8 data bits, no parity, 1 stop bit, no flow control),
and then press ENTER to display the HMI prompt.
If there is no communication with the WRS, verify that the battery is properly inserted and the
plastic insulating strip is removed.
c. Type BIND RSX a (a = last 4 digits of EUID of the new RSX) and press ENTER.
4. When the new RSX and WRS successfully bind:
• The RSX's indicator light is lit in yellow for 10 seconds.
• The associated WRS issues a CHECK RSX command to verify wireless link quality.
5. If using HMI commands to bind, disconnect the computer from the WRS.
