If the DL16CAN does not communicate with TEMES after inserting a new SRAM card, then the following procedure might be helpful:
•Turn DL16CAN off
•Bridge pin 2 and pin 3 (= two lower pins) of the connector LOGIC I/O, e. g. with a straightened electrically conducting paper clip
•Turn DL16CAN on (the display is invalid due to a blocked communication with the LCD)
•Wait 5 seconds
•Remove the bridge (e. g. remove the paper clip)
•Program the DL16CAN with TEMES
