That \u003cu\u003emay\u003c\/u\u003e indicate that the\ndevice has been optioned with the RS-422\nserial protocol instead of the RS-232, so my PC's 3-wire\nserial card can't communicate, but I have not explored this\nfurther. In any case, all the important\nparameters for the device are accessible via the front panel\nkeypad, so the serial I\/O is probably unnecessary for most\napplications. \u003c\/em\u003e\u003cem\u003eI have not explored the 86-729-15\nand 86-383-5 expansion cards for lack of documentation, but I\ndo see some config options coming up on the front panel so I\nassume they\nare working as they should, but this is not guaranteed. The\ninternal Lithium memory\nback-up battery has just been replaced so that should not need\nfurther attention for some years.
