POWER INPUT
There are differ ent power I/O options for the RPC-2350
and RPC-2350G. Read this carefully to determine which
one applies to your board.
The RPC -2350 and RPC-2350G have different input
power options. T he RPC-2350 oper ates from + 5,
±0.25VDC only.
T h e RP C - 2 35 0 G o p er a te s fr o m ei th e r + 5 , ±0 . 2 5 VD C
or + 6.5 to + 30V DC. To operate from 6.5 to 30V,
make sure jumper W8 is installed. This connects + 5V
regulated output to the board.
If you intend on using + 5V power out, be sure to read
"Heat sinking" below for related information.
+ 5V input current, for budgetary purposes, is about 250
Ma. The RPC-2350 uses slightly less power.
Both models generate voltages for RS-232 and analog
outputs are generated on card. The RPC -2350G
