2 kV Modem Important New Features Call in on outage Master/Slave –Communicate with all meters with a single phone call On-line “real time” view of critical service data –Phasor diagram of phase voltages & currents –Instantaneous demand and PF information –Diagnostic counters –Caution and Error status Call origination window Improved call retry algorithm
3 kV Modem Modem Overview 2400 baud internal modem option board –Also works at 1200 or 300 baud Call Answer and Origination Shared phone line friendly (handset or other equip.) Line sharing - up to 5 meters on one phone line LED’s for “off-hook” and “carrier detect” Test Call capability Designed for open systems & third party integration –Designed to meet ANSI C12.18, C12.21, and C12.19 –Supports UTS “I” command
4 kV Modem Call Origination Schedule –Weekly or Specific Date & Time Event –Cautions, Errors, Diagnostics –Power Restoration –Power Outage (optional) Up to 3 phone numbers –Primary & Alternate defined for each call type Retry Algorithm (except for outage calls) –Up to 5 retry “groups”, up to 5 calls per group.
5 kV Modem Call in on Power Outage Optional capability to call during a power outage Requires additional battery pack and “C” soft switch Programmable features to minimize battery use –Length of power outage before placing call –Minimum time between power outage calls –Separate Retry Algorithm Will try two times only - conserves battery
6 kV Modem Shared Phone Line Friendly Answer window Programmable number of rings Call origination window Answer lock-out feature –Prevents answering next call after no carrier signal Other phone detect circuitry –Won’t initiate call when line is busy –Hangs up if handset is picked up during a call
7 kV Modem Master / Slave Operation Up to 5 meters on a single phone line –1 Master, 4 Slave units May communicate with all units in one phone call Must program answer parameters identically –Answer window –Number of rings –Baud rate Must disable “other phone detect” Call origination must not overlap
8 kV Modem Option Board Compatibility If modem board present, must use I/O-2 and LP-2 –I/O-2 with cable: 9938287001 –I/O-2 without cable:9938287002 –LP-2 without battery:9936887001 –LP-2 with battery:9936887002 Revenue Guard board not affected by modem –Catalog number:9938280001
