The RS-232 Data Sharer has LEDs, RTS toggle switches, and
jumpers for easy configuration and diagnostics.
• 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.
