RS-232 ASCII Controlled Remote AC Power Switch - SPS-01
The Serial Power Switch SPS-01 controls AC power to any remote equipment by using ASCII commands received through an RS-232 interface. The SPS-01 allows AC powered equipment to be turned on, off, or power cycled from any remote PC, terminal, or other RS-232 connection. No configuration is required, however the dwell time for a power cycle may be set.
The SPS-01 also echos commands and provides status back to the controlling device so the remote operator knows if power to the controlled device is on or off. If the connection to the controlling terminal is lost, the SPS-01 maintains the current status of the switch.
The SPS-01 may be used in conjunction with any device having a 9600 bps RS-232 interface... DCB remote access switches, multiplexers, or any other devices with an RS-232 output port. Commonly used for typical out-of-band reboot and out of band power control.
The standard model is configured for 120 Volt AC. A 220/240 Volt AC model is available. For the 220/240 Volt model, specify the power adapter required, and be aware that there is a single relay in the unit. This product is not appropriate for 220/240 volt applications where both sides of the AC line must be switched.
One AC power port
One RS-232 control port
Connector: RJ-45 (8-wire)
Various RJ adapters available to PC-9pin, PC-25pin, Modem, etc.
The SPS-01 requires only Rx and Gnd connections, and returns responses on Tx if present
Input commands are received from the RS-232 port at 9600 bps, 8N1 or 7N1
A 220-240 VAC, export model is available. For the 220/240 Volt model, specify the power adapter required, and be aware that there is a single relay switching only one line of the AC in the unit. This product is not appropriate for 220/240 volt applications where both sides of the AC line must be switched.
This product uses a solid state relay switching the AC power for long term reliability. Some applications may require a mechanical relay, this product is not appropriate for those applications.

The SPS-01 responds to commands received via the RS-232 port. Commands may be verbose or quiet. Verbose ommands are ASCII commands using either upper or lower case letters and numbers terminated by a
(return key). Quiet commands are single letter commands and do not require a terminator. After acting on each command, a response is returned. Commands are echoed.
Verbose Quiet Use on 1 Power ON off 0 Power off flip f Invert state cycle c Invert, pause, invert state The cycle command takes a single argument, NNN, number of seconds to pause during the cycle. Once entered, this value is saved until changed with another cycle NNNN command or a power cycle. The quiet command "c" does not allow the parameter and uses the last saved value. Save this value through power cycles by using the Write command. Enter Key Enter Key Show current state show s Show current state quiet v Toggle quiet/verbose command mode write w Save current settings. This will save the cycle time, verbose/quiet mode, and power state to non-volatile memory. If power is cycled to the SPS-01, the last saved settings will be restored. help ? Display help screen
