PMAC Product Guide E103: Watchdog Timer Disable Default Configuration E103 OFF If E103 is installed the watchdog safety function will be disabled. This jumper is for testing purposes only. E106: Power-Up/Reset Load Source Default Configuration E106 OFF If E106 is installed when the PMAC-Lite executes its reset cycle, PMAC enters a special re-initialization mode that permits the downloading of new firmware either through the serial port or the bus port. Under these conditions, an appropriate program like Delta Tau’s PEWIN Software allows the downloading of a firmware file. Note: Compiled PLCs must be recompiled for running under a different firmware version.
Before attempting to upgrade PMAC operational firmware, make sure all of PMAC configuration has been stored to disk on a backup file. Also, if compiled PLCs are used, make sure to store their source code separately, which is not saved automatically in a backup file. After the firmware has been changed and before the memory configuration has been restored, it is important to send the $$$*** command to clear all memory and buffers. Communication Jumpers E9-E10, E13-E14: Serial Interface Configuration Control The E9, E10, E13, and E14 jumpers control whether the RS-232 serial port will be in DCE or DTE format.
The default configuration permits straight-across connection to a PC DB-9 serial port. Jump, E9-1 to E9-2 to allow RXD/ to be input on J4-3. Jump E10-1 to E10-2 to allow TXD/ to be output on J4-5.
