Connecting A Serial Device - Moxa Technologies oncell G2100 Series User Manual

OnCell G2100 Series User's Manual
A terminal block adaptor with power jack connector is provided to connect to AC power instead of
DC power. Compatible AC power adaptors are listed on the Moxa website, www.moxa.com.
ATTENTION
Always install the antenna first and then connect power. Do not connect power if the antenna has
not been installed! Doing so may damage the unit.

Connecting a Serial Device

The RS-232 serial interface come with 15 KV ESD serial line protection and matches the pinouts
of a standard D-shell connector. A serial device or PC COM port can be connected with a DB9(M)
to DB9(F) serial cable, such as Moxa's CBL-F9M9-150 (100 cm) or CBL-F9M9-20 (20 cm).
For OnCell G2150I Only
A separate 5-pin terminal block connector on the bottom panel is used for RS-422, 2-wire RS-485,
and 4-wire RS-485 connections. A built-in 120 Ω terminal resistor can be activated by DIP switch
if required. Pull high/low resistor adjustments are also allowed. Both the RS-232 and RS-422/485
interfaces come with two types of protection: (1) 2.5 KV RMS isolation for 1 min and (2) 15 KV
ESD serial line protection.
RS-422/485 settings are configured by DIP switch, on the bottom panel.
Switches 1, 2, and 3 select the serial interface.
Switch 4 enables or disables the termination resistor.
Switches 5 and 6 set the pull high/low resistor.
