Connecting Serial Controllers to the P2000 Comark
Server Running Software Version 3.11
This document describes how to connect supported serial controllers to the P2000 Comark
server running software Version 3.11. P2000 supports the following serial controllers:
• S321-DIN
• D620
• D600-AP (Version PS 155B or higher)
• D620-TIU
• S320
• P900
If installing serial controllers, you may need the following equipment:
• Digi® AccelePort® serial adapter board (installed at the P2000 server)
• PC232 converter (S321-DIN and P900 controllers excluded)
• B&B Electronics RS-232 to RS-485 converter (model 485OT9L) (S321-DIN controllers
using serial communications only)
Note: The S321-DIN can use serial communications with the RS-232 to RS-485 converter,
or it can communicate via IP using the Digi One® SP converter. This document covers both
scenarios.
P2000 supports a controller loop configuration in which most serial controllers connect to the
server using a PC232 converter and an AccelePort connector box. See Figure 1 for an
illustration of a P2000 system component configuration with serial controllers.

Connecting Serial Controllers
The following sections describe the hardware components needed to support serial
controllers (D620, D620-TIU, D600-AP, S320, and P900), including how to connect the
controllers to the system and establish communications. These components are not supplied
and must be purchased separately.
Note: This section does not include instructions for installing S321-DIN controllers. For
information on connecting these controllers, see Connecting S321-DIN Controllers on
page 13.
Note: The sections on the current loop converter do not apply to the P900 controller. For
more information on the P900 controller, refer to the P900 Installation Manual (Part No.
09-9133-01).

Installing the AccelePort Serial Adapter
The AccelePort board is an expandable serial communication adapter that provides each
server with additional connections to serial controllers (S321-DIN controllers excluded).
Install the AccelePort board in one of the available PCI slots. After installing the AccelePort
board, connect the cable to the board’s interface. Follow the manufacturer’s documentation
for detailed instructions on installing the board.
Note: When configuring the AccelePort, name your devices as COM1, COM2, and so on.
The AccelePort does not support other names.
AccelePort to PC232 Installation
The AccelePort module provides additional RS-232 serial ports. The module is connected to
the AccelePort PCI board in the server by a DB44 RS-232 cable. Connect one end of the
DB44 cable to the AccelePort COM port, and the other DB44 end to the CPU port on the
module. See Figure 2.

Current Loop Converter
The D620, D620-TIU, D600-AP (Version PS 155B or higher), and S320 controllers
communicate with the system via the Johnson Controls® proprietary Nodal Protocol B. The
current loop converter converts standard serial communication to Nodal Protocol B to allow
the P2000 Database Server to communicate with these controllers.
Current loop converters are available in two models:
• Model PC232-S4-1 Accommodates 4 loops and operates on 120 VAC
• Model PC232-S4-2 Accommodates 4 loops and operates on 240 VAC
Both models use the same type of enclosure for mounting. If installing only one 4-loop
converter, communication can be established with up to 64 controllers. If installing two
4-loop converters, communication can be established with up to 128 controllers. The
enclosure contains a tamper switch, transformer, EMI line filter, and current loop converter
Printed Circuit Board (PCB).
Specifications
The environmental specifications for the Field Panel Interface board are the same as for the
computers. The specifications of the current loop converter are listed in Table 1.

PC232-S4-X Converter Installation
Install the PC232-S4-X enclosure on a wall or other mounting surface in a restricted-access
area with an ambient temperature between 32° and 122°F (0° and 50°C) and a relative
humidity between 0 and 95 percent.
Note: High heat and humidity can be harmful to electronic equipment and contributes to
early component failure. Long life and reliable operation can best be obtained by installing
the converter in an environment which is comfortable to a person.
Suggested installation locations include a locking utility closet, a crawl space, or inside a
suspended ceiling (if necessary). Install the unit so the door can swing fully open to the right.
The location must allow free flow of air over all exposed surfaces.

The converter can function in any position, but we recommend mounting it flat against a wall
with the hinge to the right.
To be UL-compliant, the Current Loop Converter must be located in the same room and
within 20 feet (6.1 m) of the Proprietary Station.
Installing the Enclosure
To meet UL requirements, the PC232-S4-X board must be installed in the enclosure supplied
for the PC232-S4-X. This enclosure has four corner holes for mounting (see Figure 3). The
diameter of these holes is 0.196 inches (4.98 mm).
The enclosure has knockout holes for cable entry. You can bring cables to the mounting
location and terminate them before or after the enclosure installation, as dictated by the
requirements of the installation.
To install the enclosure:
1. Remove the PC232-S4-X board from the enclosure by disconnecting the power cable
from J6 and the tamper switch cable from J1. Then, remove the four screws securing the
PC232-S4-X board to the enclosure.

2. Set aside the screws in a safe place, so you can use them to replace the board into the
enclosure.
3. Hold the enclosure in the desired location on the mounting surface and use as a template
to mark the location of the four mounting holes that correspond to the holes shown in
Figure 3.
4. Bore holes in the mounting surface at the four marks. If necessary, install hollow-wall
anchors.
5. Mount the enclosure on the wall using appropriate hardware.
6. Bring the cables to the mounting location, allowing enough excess cable for a service
loop.
7. Determine the point of entry for each cable and remove the appropriate knockout(s).
8. When using conduit, attach appropriate conduit fasteners to the conduit in the enclosure.
9. Install the PC232-S4-X board removed in Step 1.
10. Reconnect the power cable to J6 and the tamper switch cable to J1. You have completed
the enclosure installation.
