Chapter 18 Configuring Power Over the Serial Ports
75
Serial Power Feature
The Serial Power feature available for the Digi One TS, PortServer TS 2
MEI, and PortServer TS 4 MEI allows the Digi device to power a serial
device (power out) or use a serial device to power the Digi device (power
in). The advantage of this feature is to eliminate an external power supply.
Power out is available on all ports through Ring Indicator (RI) or Data
Terminal Ready (DTR). Power in is available only through RI and only on
port one (1). The Serial Power feature is active on a specific port when that
port is configured for RS 232 operation.
•
The power out budget equals one (1) watt (the total amount of
power available). The available power can be divided in any combi-
nation between the ports but the following rules must be observed:
— RI = 5 volts @ up to 200 mA (max)
— DTR = 9 volts @ up to 100 mA (max)
— You may use DTR or RI as the source of power (power out) on
any port but you may not use both DTR and RI on the same port.
•
Pinout information
— RI is pin 1
— DTR is pin 9
•
RI signaling is lost when the pin is used for power
Configuring RI Power
RI Power In
Ring Indicator (RI) power in accepts power into the Digi device server only
on port one. Power in is available using the RI pin. The Digi device requires
power in the range of 9-30 VDC @ 525mA (max). Ports 2, 3, and 4 can still
supply power to a serial device through the RI or DTR pins for each port.
When using power in through the RI, the external power supplies (both
powered Ethernet and the barrel connector power supply) are inoperative.
Altpin will not work for RI power in.
1. Open the device unit enclosure and move the black jumper to the
following settings:
P-6 jumper on pins 1 and 2

Note:
When the jumper is placed correctly for
power in, the jumper will set on the pins
closest to the edge of the board. The left
arrow indicates the open pin and the right
arrow is pointing to the jumper.
