C•CURE apC/L Technical Manual
Setting Up the apC/L Panel
6-9
W2 EPROM size settings Jumper W2 determines if the apC/L is
equipped with EPROMs or Flash EPROMs up to 2 Mbyte in size or 4Mbyte
EPROMs. When W2 is in the A position, 4 Mbyte EPROMS or FLASH are
installed. When W2 is in the B position, EPROM or FLASH sizes from 512
Kbyte up to 2 Mbyte are installed.
Leave these settings in the factory default position.
W3 SRAM Size Jumper W3 determines the size of RAM installed on the
apC/L. When W3 is in the IN position, 512 Kbyte SRAM is installed. When
W3 is in the OUT position, 128 KByte SRAM is installed.
Leave these settings in the factory default position.
W4 - W5 When jumpers W4 & W5 are in the OPEN position, the apC/L is
not the last unit in a RS-485 multidrop line. When jumpers W4 & W5 are in
the CLOSED position, the apC/L is the last unit on the RS-485 multidrop line.
W6 Cabinet Tamper Override Leave W6 open for normal operation.
Closing W6 overrides the wall and door tamper switches. Close the jumper
for diagnostic purposes only or when using the apC/L outside the apC/L
cabinet.
W7 Leave W7 in the A position for normal operation. The apC/L will not
operate properly if W7 is not in the A position.
W8 Jumper W8 is not implemented on the apC/L, circuit board Rev. A or
B. On Rev. C boards, normal operation of the power fail condition while
running with an internal battery backup is achieved with W8 installed. This
condition disables the external power fail P3 connection (leave open). With
W8 removed, P3 is enabled. A short across P3 indicates that the power is
okay, while an open on P3 indicates a power fail condition.
W9 - W14 Host Port Communication Protocol Jumpers W9 through
W14 determine the type of transmission at the host port. Close the A section
of W9 through W14 if the apC/L connects to the host through the RS-485
communications format. Close the B section of these jumpers if the apC/L
connects to the host through RS-232C format.
