Installing the serial switching control card
The serial switching control card includes static sensitive
components. Follow proper ESD procedures when handling the
card.
1. Set the priority select jumper JP1.
Senstar-Stellar recommends using the default setting with the shunt installed
on pins 1 & 2 for Priority A.
2. Slide the card into Slot 16 in the switching chassis. Ensure that the card is
properly seated.
3. Connect J1 on the switching control card to J9 on the CU A MFC. Use a four-
wire telephone cable terminated at both ends with RJ11 modular phone
jacks. See
Figure 2-4 Multifunction card external alarm O/P, page 2-11
for the
MFC pinouts.
4. Connect J3 on the switching control card to J9 on the CU B MFC. Use a four-
wire telephone cable terminated at both ends with RJ11 modular phone
jacks. See
Figure 2-4 Multifunction card external alarm O/P, page 2-11
for the
MFC pinouts.)
5. Connect AC power to J5.
Serial data switching cards
There are two types of serial data switching cards, supported by Senstar 100. The
older model (SP-100224) is no longer available, but it can be used with the
current system. The newer model (J2BA0200) routes transmitted data from the
single-ported device to both CU A and CU B. Only the transmitted data line from
the active (primary) CU is switched (to the single-ported device). This
arrangement provides half-redundant communications with the single-ported
device.
Figure b-12: Serial switching card, page b-15
illustrates the Senstar-Stellar
serial data switching card (J2BA0200).
