MOUNTING POSITION - The PulseConnex 9903B can be mounted in any position. Four mounting holes are
provided.
POWER INPUT - The PulseConnex 9903B is powered by an AC voltage of 12 volts. Connect the 12 VAC source to
terminals 5 and 6 of the J1 connector.
METER INPUT - The PulseConnex 9903B has two 2-Wire (Form A) pulse inputs. Connect the 9903B's "K1" and
"Y1" input terminals to the meter's "K" and "Y" output terminals. Connect meter #2 to the K2 and Y2 terminals. The
two inputs are configured to accept dry contact switches or pulse outputs meaning that no external voltage is
required. A "pulled up" +13VDC wetting voltage is supplied internally on each Y terminal. The 9903B's "K" terminals
are the common return. Each closure of the meter's K-Y output will "pull down" the input line to the common return.
Each time a pulse is received, the RED LED on the cover corresponding to that input will light indicating that the
pulse input is active. The 9903B is compatible with either fixed width "momentary" pulses or 50/50 duty-cycle
"toggle" pulses. Depending on the length of the fixed time pulse width, you may not be able to see the LED light.
The minimum "on" pulse width is 20mS. A toggle pulse mode is generally more desirable. The absolute maximum
pulse rate on each pulse input is 10 pulses per second. A good rule of thumb is to program the meter with a pulse
constant that gives approximately 2 pulses per second at maximum demand and at least one pulse every 4 seconds
at the minimum demand.
OUTPUT - The 9903B is configured as a web client, not a server. It sends data every 5 seconds to the
PulseConnex cloud server. It does not respond to queries. Plug a standard ethernet cable into the 9903B's RJ-45
jack. Connect the other end of the cable into your network's router, switch or hub. The 9903B's default network
mode is DHCP. When it is connected to an ethernet network (and powered up), the network's router will assign it a
dynamic IP address. Once the 9903B is reporting to the PulseConnex server you can now set up an account. Make
note of the 9903B's MAC address. This is a 12-digit number which starts with 0090C2 or 00C033. You will need this
number for setting up your account if it has not already been set up by the factory. The PulseConnex can also be
configured with a static IP address using the USB Serial Port.
OPERATION - All operational settings are programmed into the 9903B from the www.pulseconnex.com website.
The 9903B will report the power use information to the PulseConnex service every 5 seconds. You can observe this
if desired by viewing the Yellow LED on the RJ-45 Ethernet jack and the 8 Green LEDs on the side of the
PulseConnex unit. The communications are very short so you may have to look very closely to see the Yellow LED
light. (Also see Diagnostic LED's on Troubleshooting page.)
NOTICE - The 9903B MUST be operating and communicating with the PulseConnex Server before setting up your
account, unless this has already been done at the factory.
