Allocations and wiring guidelines for CN1, CN2, and the Terminal Block are pro-
vided on the following pages. CN4 and CN5 are described in the next section,
Communications Interfaces. CN3 is not for customer use.
The following table shows the terminal assignments for CN1. The four DC+ ter-
minals are internally connected, as are the four DC– terminals. The three BANK
and three ING terminals are used to select the current memory bank as ex-
plained following table. As the three ING terminals are internally connected, it
does not matter which is used. Do not connect anything to the unused terminals.
For the E5ZD-4jjj-E, terminals 30 to 32 are also not used.

nal circuitry may be damaged.
