1.0 Introduction The RFS-SP8T is an single pole, 8 throw solid state RF switch, with signal bandwidth of 0.1 GHz to 8 GHz. The switch position is set by pressing one of eight front panel momentary switches, or via LAN interface. An RS232 port is provided for configuring the switch IP address, and other operating parameters Figure 1 –...
The current RF switch position is indicated by a red LED. A green power indicator LED is also mounted on the front panel Figure 2 – RFS-SP8T Front Panel RFS-SP8T RF Switch Matrix Users Manual Document number 2000481...
RF1-RF8. Figure 3 – RFS-SP8T Back Panel 3.1 RS232 Connector A standard DB9F is located on the right side of the RFS-SP8T back panel. The connector pinout is provided in the table below: Pin Number Signal...
Momentary switch that generates a hardware reset when pressed. Note: Following reset (or power up) it takes 3 or 4 seconds for the unit to initialize and attempt to establish communication on the LAN. RFS-SP8T RF Switch Matrix Users Manual Document number 2000481...
To use the RS232 commands, connect a computer running a terminal emulator program (e.g. Hyperterm) configured for 9600 baud, 8 bits, no parity, 1 stop bit. Upon reset, the RFS-SP8T will display the sign on message as shown below (all examples use Hyperterm): The ‘>’...
IP address with lead zeros suppressed assigned by the DHCP, or the default static IP address if static IP was selected (by SD command) Example: RFS-SP8T RF Switch Matrix Users Manual Document number 2000481...
Response: IP address: aaa.aaa.aaa.aaa.aaa gateway address: bbb.bbb.bbb.bbb network mask: ccc.ccc.ccc.ccc name server: ddd.ddd.ddd.ddd Where: aaa.aaa.aaa.aaa bbb.bbb.bbb.bbb ccc.ccc.ccc.ccc ddd.ddd.ddd.ddd are IP addresses in standard dotted decimal format with lead zeros suppressed.

4.6 “SD” Command Function: Select static IP or DHCP Command format: “SD<enter>” In the following example, the user selected ‘0’ for DHCP. Selecting ‘1’ would select static IP addressing. Example: RFS-SP8T RF Switch Matrix Users Manual Document number 2000481...
5.0 Socket Interface The RFS-SP8T firmware provides socket commands to set/read the RF switch position, lock/unlock the front panel momentary switches, and read the firmware version and serial number. Each command is described in the following sections. The examples assume a TCP/IP socket has been established with the RFS-SP8T on port 14000.
5.2 GETSW Command Function: Read the current RFS-SP8T RF switch position Format: GETSW Response: Switch=n Where n is the current RF switch position, 1<=n<=8 Example: If w is a previously opened write network stream, and r is a previously opened read network stream, then w.Write(“GETSW”);...
Function: Disables the RFS-SP8T front panel momentary switches Format: Response: 0x03 Example: If w is a previously opened network stream to the RFS-SP8T, then w.Write("LFP"); disables the front panel switches. The control software should wait for the acknowledge byte 0x03 to be returned before sending additional commands...
Function: Enables the RFS-SP8T front panel momentary switches Format: Response: 0x03 Example: If w is a previously opened network stream to the RFS-SP8T, then w.Write("UFP"); enables the front panel switches The control software should wait for the acknowledge byte 0x03 to be returned before sending additional commands...
5.5 GETFV Command Function: Retrieves the RFS-SP8T firmware version Format: GETFV Response: nVVV…V Where: n is the number of characters in the serial number VVV…V is a variable length firmware version string Example: If w is a previously opened write network stream, and r is a previously opened read network stream, then w.Write("GETFV");...
5.6 GETSN Command Function: Retrieves the RFS-SP8T serial mumber Format: GETSN Response: nVVV…V Where: n is the number of characters in the serial number VVV…V is the variable length serial number string Example: If w is a previously opened write network stream, and r is a previously opened read network stream, then w.Write("GETSN");...
