The Data cabling of PG100 Local Pager is made via the 3-pin CONSOLE
connector on the SPS48 card. The signaling between the SPS48 and PG100 is
illustrated in the following table:
SPS48 Card
PG100 Card
CONSOLE Connector Pin No Signal RJ Plug Pin No
1 Data 1
2 +12 VDC 6
3 GND 2
The input of +8 VDC is regulated to +5 VDC by PG100.
PG100 can be also directly connected to mains voltage through a 12 VDC power
adaptor. Normally, PG100 receives power over the data cable. However, if the data
line of the system is overloaded due to the existence of many OP48(-H) and
LT48(-H) telephones or DSS40 and DSS80 modules connected to the system, it is
preferable to feed PG100 over the power adaptor that is to be procured locally.
The dimensions of PG100 are 24 cm x 19 cm x 4.5 cm and the weight is 0.5 kg.
