2.3.3 COM2 ~ COM6 Connector
The ARK-3381 provides five D-sub 9-pin connectors for RS-232/422/485
communications. The default setting of COM2 ~ COM6 is RS-232. Please
refer to section 3.3 ~ 3.7 “Jumper Settings” and Chapter 6 “Full Disassem-
bly Procedure” for set up information. The pin assignments of COM2 are
different than COM3 ~ COM6. Table 2.5 and table 2.6 shows these differ-
ences.
The RS-422/485 mode of COM2 can be configured by replacing the
internal COM2 cable with a new cable (Part Number of 1700001967),
and adjusting a jumper. The new cable is in the accessory box.
