Technically Speaking
The
•LEDs include PWR, “slave port” RTS, and “master port” CD, CTS, and RXD.
•There is one RTS toggle switch for each “slave port.” Use these switches to enable or disable the Sharer’s detecting an RTS signal on any of the slave ports. Disabling a port’s RTS detection will prevent that port’s device from accessing the modem or CPU. This is useful if you want to isolate a slave device, especially if the device is malfunctioning.
•Using jumper W1, you can tie signal ground to frame ground.
•With jumper W2, you can set the amount of time you want the RTS signal to delay as it passes through the Data Sharer from a slave port to the master port.
•How you set jumper W3 determines whether the Sharer will broadcast data out of all slave ports, or out of only the active ports.
•Jumper W4 determines whether the slave ports will be (a) polled for RTS sequentially, or (b) prioritized with Port A given the highest priority and Port D or H the lowest.
•A set of “timeout” jumpers keeps a slave from monopolizing the master.
