Drawing 3-7: BulletPlus Rear & Side View
The Data Port (RS232 DCE) on the side of the unit is used for
RS232 Serial Data based field devices at 300 bps to 921kbps.
The Ethernet Ports (2LAN/WAN) are 10/100 Mbps RJ-45
interfaces used to connect devices Ethernet based field devices.
Programmable I/O– The Bullet has 2 programmable Analog/
Digital Inputs or 2 Digital Outputs. Maximum recommended load
for the output pin is 150mA @ 30 Vdc (Vin).
Vin+/Vin– is used to power the unit. The input Voltage range is
7-30 Vdc.
PoE– The Bullet can also be powered using Passive PoE on the
Ethernet Port (WAN), via a PoE injector.
