2.3.2 Serial Interfaces (COM2)
When creating your own cable, follow the instructions listed below:
<With RS-422>
• The following pairs of pin #’s must be connected to each other.
#18 (CSB) <—> #19 (ERB)
#21 (CSA) <—> #22 (ERA)
• When connecting the RS-422 cable and the #9 (TRMX) and #10 (RDA) points, a
termination resistance of 100
Ω Ω Ω Ω Ω
is added between RDA and RDB.
• When making a cable for a Memory Link system, be sure to use a 4-wire type.
<With RS-232C>
•
Do not use the following pins: 9 (TRMX), 10 (RDA), 11 (SDA), 15 (SDB), 16
(RDB), 18 (CSB), 19 (ERB), 21 (CSA), 22 (ERA).
• The #1 (FG) terminal should only be connected if it is required by the device being
connected to.
• This unit’s serial port is not isolated, therefore, it is important that
you connect the SG (Signal Ground) terminals. If this is not done,
the RS422 circuit may be damaged.
• Pin 14 (VCC) DC5V output is not protected. To prevent damage or
unit malfunction, be sure to use only the designated level of current.
This interface is used for RS-232C data transfer. The GP-2301 Series unit is not
equipped with this interface. (Plug-Type Connector)
Recommended Connector: Dsub9pin socket XM2D-0901<made by
OMRON>
Recommended Cover:
Dsub9pin cover XM2S-0913<made by OMRON>
Jack Screws: XM2Z-0073<made by OMRON>
• Since Pin#9(RI/VCC) is unprotected, be sure to keep the output cur-
rent within the rated range.
• The GP-2301T does not have an expansion serial I/F.
Use inch type screws (#4-40UNC) as set screws.
