By receiving a short sequence of normal alphanumeric characters, the RS51-SPR-RELAY can control either a single relay, or the individual relays on up to 16 addressable RS51-SPR boards.
A female DB9 connector on the RS51-SPR board matches the pinout of the serial port of an IBM PC equivalent computer and can be connected to it with a common DB9 pin-to-pin male-to-female cable.
An additional male DB9 connector matches the pinout on the computer and provides a method of "chaining" multiple boards with the same cable.
Up to 16 boards can be chained through these connectors and can be optionally powered from the power supply connected to the first board in the chain.
An additional RS51-SPR board can be connected to Serial port 2 with its included cable (or equivalent wiring), and other boards with up to 16 unique "addresses" connected down the chain in a similar manner. Additional boards can have the same or different address as other boards in the chain and can respond to the same or different commands. Refer to the RS51-SPR reference manual under "On-Board Configuration Jumpers", "Board Address".
The RS-232 protocol on all connected boards should be selected to match the transmitting device. Refer to the RS51-SPR reference manual under "On-Board Configuration Jumpers", "Baud Rate and Character Echo". The default factory configuration is set to 9600 baud, 8 data bits, 1 stop bit, no parity, no echo.
All boards after the first board in the chain can be powered from the power supply connected to the first board. Refer to the RS51-SPR reference manual under "On-Board Configuration Jumpers", "Power to serial port connectors". The default factory address is 0 (zero).
When entering commands "by hand" from a terminal program while testing, editing using the backspace and arrow keys is not available. Messages with typos must simply be re-entered.
Commands with errors will result in the word "Error" returned from Serial port 1. Only error-free commands will be sent to Serial port 2 to be received by any additional boards connected.

Two RS-232 serial ports are available on the board-
- One uses a DB9 female connector with a pinout that matches the serial port of an IBM PC equivalent computer when using a standard DB9 pin-to-pin male-to-female cable.
- The other uses a DB9 male connector with a pinout that emulates the IBM PC serial port for connection to other devices that connect to that standard.
The RS51-SPR also includes an on-board relay with 10 amp Form C contacts and screw terminal connections.
It can operate on 9 to 12 volts AC or 11 to 14 volts regulated or unregulated DC, with a coaxial power connector for connection to a wallblock transformer as well as screw terminals for other voltage sources.
The RS51-SPR is shipped with the items needed to quickly and immediately connect to an IBM PC compatible computer and to begin operating the device- A wallblock power supply, RS-232 cable, and detailed Reference Manual.
Operating environment:
Temperature: 0-50 degrees Celsius (32-122 Fahrenheit)
Humidity: 30 to 80 percent, non-condensing
Form "C" Relay Contacts:
Maximum voltage: 30 volts, AC or DC
Maximum current: 10 amps

Connecting power to serial port 2 allows an RS51-SPR to power another board when used a part of a chain of addressed boards. Connecting power to serial port 1 allows an RS51-SPR to receive power from another board. When used in this manner, the first board in the chain should have only serial port 2 connected to power, and the rest of the boards should have both serial 1 and serial 2 connected to power. Power should then be applied only to the first board.
The following are pinouts of the serial port connectors:
Serial Port 1, DB9-Female: Serial Port 2, DB9-Male PC signal Pin RS51-SPR Signal Pin RS51-SPR Signal DCD in 1 1 receive 2 transmit 2 receive transmit 3 receive 3 transmit DTR out 4 4 ground 5 ground 5 ground DSR in 6 6 RTS out 7 7 CTS in 8 8 RI in 9 optional power 9 optional power
On serial port 1 pins 1, 4, and 6 are tied together and pins 7 and 8 are tied together.
