APPENDIX G
WHAT'S NEW, AND WHAT HAS
NOT CHANGED IN THE SK-ACPE?
The SK-ACPE is Secura Key's replacement for the legendary SK-ACP.
The "E" indicates the built-in Ethernet capability. The main reason for this
upgrade is the obsoletion of the ACP's 16-bit Hitachi main processor unit.
Due to the large number of legacy systems in the field, we have designed the
SK-ACPE as a drop-in replacement for the SK-ACP . While the SK-ACPE is almost
functionally identical, we have also included some long-needed improvements
made possible by the powerful new ARM Cortex M3, 32-bit RISC processor.
1. This unit is functionally identical to the SK-ACP . It will work with older versions
of SK-NET software, including Versions 3, 4 and 5.
2. Connectors and their functions are identical to the SK-ACP . You can replace an
older board with a new one without rewiring the connectors. Note that connectors
J3 and J4 are now located on the side of the board.
3. The Ethernet Adapter is now integrated into the panel. Connect to the LAN via
RJ-45 connector J10 at the lower right-hand corner of the board. A separate module
is not required. Multiple Ethernet connections in one system require SK-NET-MLD. IP
Addresses must be configured using a terminal program (See Appendix D).
4. Status LED functions and locations have been changed – see Figure 4 for details.
5. The jumper that changes input circuits from NC to NO has been removed.
On the SK-ACPE, this setting is now changed in the SK-NET software (Version 5.1 is
required). If you do not have Version 5, the inputs will default to NC.
6. A new Jumper JP1 enables RS-232 signals either at J12 or J11 and J10 (See
Figure 3). Enabling RS-232 at J12 allows the use of the optional SK-WLSE-LAN
wireless LAN Module. Enabling RS-232 at J11 and J10 allows the connection of a
computer at the Field Service Port J11 or wiring of a serial connection to J10.
The SK-WLSE-MOD is an entirely new module, and is not compatible with the
SK-WLS-MOD module used with the SK-ACP .
7. The RJ-11 Jack has been removed. The SK-QUICKCONN and SK-CBLSA cables
cannot be used to connect a computer to the panel's RS-232 port. A new cable,
RS-232E, is required to connect a computer to the J11 Field Service Port.
