Port Combiner Mode

With the 232XS5 set up with a DTE master port, this mode allows Slave Ports A-E to select the master port using the RTS input line. It also still allows selection from the master port via the preamble code described in the Smart Switch Only Mode section. Jumper “JP6-C” must be OFF (removed) to be in port combiner mode. Port combiner mode is not accessible when the unit is set up as a port expander, so JP6-B must be ON (installed). When RTS goes high on any of the five slave ports, it will establish a connection from that port to the master port. This works on first-come-first- served basis. If multiple ports have their RTS lines high, the port that has been waiting the longest will be next to be connected to the master port. For example (initial conditions -- no slave ports with RTS lines asserted.), in chronological order, Port C asserts its RTS line, Port A asserts its RTS line, Port D asserts its RTS line and then Port C disasserts its RTS line. When Port C asserts its RTS line, a connection will be made between the master port and Port C. When Port C disasserts its RTS line, Port C will be disconnected and Port A will be connected to the master port. When Port A disasserts its RTS, Port A will be disconnected and Port D will be connected to the master port.

For example, port A is configured as a DTE port. In order to establish a connection to the master port, port A must set RTS high (assert). The 232XS5 would recognize this as a prompt for connection to the master port. The connection would be dropped as soon as RTS on port A is brought low. Ports B-E may raise RTS at any time to request a connection. However, if port A is connected to the master port, any data sent from the devices on ports B-E to the 232XS5 will be lost. The 232XS5 does not have any buffering.
