Set the same frequency channel used by the Serial Master Station using the channel setting switch. 78 78 X10 4. Change the setting for the mode setting switch to RUN mode, and then turn ON the power. RUN TEST SET Serial Master Station Settings 1, 2, 3. . . Before turning ON the power set the function setting switch as required. ON 12345678 90 Bit 1: Hold/clear I/O data if communications errors occur Bit 2: OFF (scan list disabled) Note When the scan list is disabled, communications are performed with the number of I/O Slave Stations set using the node setting switch. Example 1: If the node setting switch is set to 2, communications will be performed with up to 02 I/O Slave Stations. Example 2: If the node setting switch is set to 64, communications will be performed with up to 64 I/O Slave Stations. Set the number of I/O Slave Stations to be connected using the node setting switch. Polling will be performed for the number of I/O Slave Stations set here. For example, if the number is set to 2, communications will be performed with only 2 Stations even if 3 or more Stations actually exist.

Change the setting for the mode setting switch to RUN mode, and then turn ON the power. 3-4-3 Confirming Connection Status Confirm the communications status between the I/O Slave Stations and Serial Master Station using the RSSI (received signal strength indicator) display. To confirm the status from the Serial Master Station, specify the I/O Slave Station to be monitored using the node setting switch. Be sure to turn ON the power to the I/O Slave Station in RUN mode before the Serial Master Station. I/O Slave Stations 1, 2, 3. . . Confirm that the mode setting switch on the I/O Slave Station is set to RUN mode. 2. Confirm that the MS and WS indicators on the I/O Slave Station are lit green.

[. . . ] = WNODE (Sum total of cycle times for all I/O Slave Stations) = WNODE (10 ms × n stations) Using Relay Stations The wireless communications delay is doubled when a Relay Station is used. = WNODE (10 ms × n stations × 2) Example 1: Using one Master Station, four I/O Slave Stations, and an input filter of 10 ms. 10 × 4 × 2 + 10 = 90 ms Example 2: Using one Master Station, one Relay Station, four I/O Slave Stations, and an input filter of 10 ms. 10 × 4 × 2 × 2 + 10 = 170 ms The calculations shown here indicate theoretical values and should be considered as a rough guide only.
